BN14.md

+If you played Exponential Idle start with the idea that BN14 will be very similar to the Lemmas from that game.
+
+BN14 will consist of a series of mathematical equation that needs optimizing. BN14 can only be completed by obtaining enough currency from the equations. It also has no levels as the reward is based on how fast you can complete it.
+
+Each equation contains several variable that can be upgraded by spending currency specific to BN14
+
+Let's imagine a very simple equation
+
+`delta p = c1/|e-c2/c3|`
+(c1 div absolute value of the natural constant e minus c2/c3)
+
+`delta p` is the amount of currency you earn every tick  
+`c1`, `c2`, `c3` are all variables that the player can upgrade in exchange for the `p` currency
+
+`c2` and `c3` increase by `1` every level and the cost to upgrade is exponential  
+`c1` increases exponentially and the cost to upgrade is also exponential
+
+So the goal here is to generate as much currency as possible. For this particular equation the goal is to increase `c1` as much as possible but also to make `c2/c3` as close to `e` as possible.
+
+An equation like this represents one part of the BN. Players will be presented with MANY different equations.
+
+Every equation contributes to completing the BN faster.
+
+I need equations that test many different aspect of "math culture", it can be chaos theory, quantum mechanic, weird polynomials, etc.
+
+All variable purchasing will be scriptable.
+
+
+All equation must have:
+- several variables that can be upgraded, at least 1 variable must be strategic in it's upgrading (upgrading too much can cause drop in performance)
+- Some sort of math twist that requires some thinking, like (-2)^c1 alters between positive and negative.
+
+Equations must be of a wide variety of difficulty the more of a math nerd you are the better your time in the BN should be but math "noobs" shouldn't be unable to complete it.

+
+## Reporting An Issue
+
+If you're about to raise an issue because you think you've found a
+problem with MathJax, or you'd like to make a request for a new
+feature in the codebase, or any other reason, please read this first.
+
+The [MathJax issue
+tracker](https://github.com/mathjax/MathJax/issues) is the
+preferred channel for [bug reports](#bug-reports), [feature
+requests](#feature-requests), [change requests](#change-requests), and
+[submitting pull requests](#submitting-pull-requests), but please
+respect the following restrictions:
+
+* Please **search for existing issues**. Help us keep duplicate issues
+  to a minimum by checking to see if someone has already reported your
+  problem or requested your idea.
+
+* Please **do not** use the issue tracker for personal support
+  requests (use [the MathJax User Group](https://groups.google.com/forum/#!forum/mathjax-users)).
+
+* Please **be civil**. Keep the discussion on topic and respect the
+  opinions of others. See also our [Conduct Guidelines](#conduct)
+
+### Bug Reports
+
+A bug is a *demonstrable problem* that is caused by the code in the
+repository. Good bug reports are extremely helpful — thank you!
+
+Guidelines for bug reports:
+
+1. **Use the GitHub issue search** — check if the issue has already been
+   reported.
+
+2. **Check if the issue has been fixed** — look for [closed
+   issues in the current
+   milestone](https://github.com/mathjax/MathJax/issues?q=is%3Aclosed)
+   or try to reproduce it using the latest `develop` branch. Please
+   note that you will need to
+   [compile MathJax and make the components](https://docs.mathjax.org/en/latest/web/hosting.html#getting-mathjax-via-git)
+   in order to test MathJax from the source repository.
+
+3. **Share a live sample of the problem** — without a live page
+   it is usually impossible to debug problems; see also the [Bug Report
+   Template](#template) below.
+
+4. **Isolate the problem** — a live sample is a starting point
+   but if you want to speed things up, create a [reduced test
+   case](http://css-tricks.com/6263-reduced-test-cases/). Be specific
+   about your setup (browser, OS versions, etc). Use services like
+   [jsbin](http://jsbin.com), [CodePen](http://codepen.io), or
+   [jsFiddle](http://jsfiddle.com) to make collaboration on minimal
+   test cases easier for everyone.
+
+5. **Include a screenshot/cast as a last resort** — Is your
+   issue about a layout or design feature or bug that is hard to reproduce
+   or isolate? Then please provide a screenshot or screencast. Tools
+   like [LICEcap](http://www.cockos.com/licecap/) or
+   [SauceLabs](http://www.saucelabs.com) allow you to quickly and
+   easily record a screencasts. If you make it an animated gif, you can
+   embed it directly into your GitHub issue.
+
+6. Use the [Bug Report Template](#template) below or [click this
+   link](https://github.com/MathJax/MathJax/issues/new?title=Bug%3A&body=%23%23%23%20Issue%20Summary%0A%0A%23%23%23%20Steps%20to%20Reproduce%0A%0A1.%20This%20is%20the%20first%20step%0A%0AThis%20is%20a%20bug%20because...%0A%0A%23%23%23%20Technical%20details%0A%0A*%20MathJax%20Version%3A%20master%20-%20latest%20commit%3A%20%20INSERT%20COMMIT%20REF%0A*%20Client%20OS%3A%20%0A*%20Browser%3A%20%0A*%20)
+   to start creating a bug report with the template automatically.
+
+A good bug report shouldn't leave others needing to request
+more information from you. Be sure to include the details of your environment.

+* Browser: Chrome 29.0.1547.57
+```
+
+
+### Feature Requests
+
+Feature requests are welcome. Before you submit one, be sure to have:
+
+1. **Used the GitHub search** to check that the feature hasn't already
+   been requested.
+2. Take a moment to think about whether your idea fits with the scope
+   and aims of the project, or if it might better fit being a [custom
+   extension](https://github.com/mathjax/MathJax-third-party-extensions).
+3. Remember, it's up to *you* to make a strong case to convince the
+   project's leaders of the merits of this feature. Please provide as
+   much detail and context as possible, this means explaining the use
+   case and why it is likely to be common.
+
+### Change Requests
+
+Change requests cover both architectural and functional changes to how
+MathJax works. If you have an idea for a new or different dependency,
+a refactor, or an improvement to a feature, etc., please be sure to:
+
+1. **Use the GitHub search** to check that someone else didn't get there first.
+2. Take a moment to think about the best way to make a case for, and
+   explain what you're thinking. Are you sure this shouldn't really be
+   a [bug report](#bug-reports) or a [feature
+   request](#feature-requests)?  Is it really one idea or is it many?
+   What's the context? What problem are you solving? Why is what you
+   are suggesting better than what's already there?
+
+## Working on MathJax core
+
+You want to contribute code? We describe how below.  First, note that
+the MathJax source code is in the
+<https://github.com/mathjax/MathJax-src> repository, not the
+<https://github.com/mathjax/MathJax> repository, which contains the
+packaged component files for distribution on CDNs and the [mathjax npm
+package](https://www.npmjs.com/package/mathjax) (the source code is
+included in the [mathjax-full npm
+package](https://www.npmjs.com/package/mathjax-full)).
+
+### Key Branches & Tags
+
+MathJax uses several permanent branches in the [MathJax source repository](https://github.com/mathjax/MathJax-src):
+
+- **[develop](https://github.com/mathjax/MathJax-src/tree/develop)**
+  is the development branch. All work on the next release happens here
+  so you should generally branch off `develop` if you are going to
+  submit a pull request. Do **NOT** use this branch for a production
+  site.
+
+- **[master](https://github.com/mathjax/MathJax-src)** contains the latest
+  release of MathJax. This branch may be used in production. Do 
+  **NOT** use this branch to work on MathJax's source.
+
+These branches reflect version 3 of MathJax, which is substantially
+different from the version 2 codebase.  Version 2 will continue to be
+maintained while web sites transition to version 3, with work being
+done using the following branches in the [MathJax distribution
+repository](https://github.com/mathjax/MathJax):
+
+- **[legacy-v2-develop](https://github.com/mathjax/MathJax/tree/legacy-v2-develop)**
+  is the development branch for changes to the legacy version 2 code.
+  Any pull requests for version 2 should be branched from here.  Do
+  **NOT** use this branch for a production site.
+
+- **[legacy-v2](https://github.com/mathjax/MathJax/tree/legacy-v2)**
+  is the branch that contains any updates to version 2 following
+  the release of version 3.  Do **NOT** use this branch to work on
+  MathJax's source.
+
+In addition to these branches, MathJax uses tags to identify the
+various versions.  These can be checked out to obtain the specified
+release; for example, `git checkout 2.7.5` would get you the files for
+version 2.7.5 of MathJax.
+
+Note that version 3 is written in Typescript, and so must be compiled
+to obtain usable javascript files, and that the components need to be
+built once that is done.  See the
+[documentation](https://docs.mathjax.org/en/latest/web/hosting.html#getting-mathjax-via-git)
+for details. For version 2, the source javascript files are not
+compressed until a release is made, so you should use the copies in
+the `unpacked` directory during development.
+  
+
+### Submitting Pull Requests
+
+Pull requests are welcome. If you're looking to submit a PR for
+something that doesn't have an open issue, please consider [raising an
+issue](#reporting-an-issue) that your PR can close, especially if
+you're fixing a bug. This makes it more likely that there will be
+enough information available for your PR to be properly tested and
+merged.
+
+##### Need Help?
+
+If you're not completely clear on how to submit/update/*do* Pull
+Requests, please check out our [source control
+policies](https://github.com/mathjax/MathJax/wiki/Source-control-policies). For
+more insights, check the excellent in depth [Git Workflow
+guide](https://github.com/TryGhost/Ghost/wiki/Git-Workflow) from
+Ghost, in particular
+
+* [Ghost Workflow guide: commit messages](https://github.com/TryGhost/Ghost/wiki/Git-workflow#commit-messages)
+
+### Testing and Quality Assurance
+
+If you're
+looking to get involved with the code base and don't know where to
+start, checking out and testing a pull request is one of the most
+useful things you could do.
+
+These are some [excellent
+instructions](https://gist.github.com/piscisaureus/3342247) on
+configuring your GitHub repository to allow you to checkout pull
+requests in the same way as branches.
+
+
+### Writing documentation
+
+MathJax's main documentation can be found at [docs.mathjax.org](http://docs.mathjax.org).
+The source of the docs is hosted in the
+[mathjax/MathJax-docs](http://github.com/mathjax/MathJax-docs) repo here on GitHub.
+
+The documentation is generated using
+[Sphinx-doc](http://sphinx-doc.org/) and hosted on [Read the
+docs](http://readthedocs.org).  You can clone the repo and submit pull
+requests following the [pull-request](#submitting-pull-requests)
+guidelines.
+
+
+### Translation
+
+If you wish to add or update translations of MathJax, please do it on
+[TranslateWiki.net](https://translatewiki.net/w/i.php?title=Special:Translate&group=out-mathjax-0-all)
+(and while you're there you can help other open source projects,
+too).
+
+For bug reports and other questions that don't fit on
+TranslateWiki.net, head over to the
+[mathjax/mathjax-i18n](https://github.com/mathjax/MathJax-i18n)
+repository.
+
+The translation files currently are for version 2, as localization
+hasn't been added to version 3 yet.
+
+## Conduct
+
+As a NumFOCUS fiscally sponsored project, MathJax is governed by the
+[NumFOCUS code of conduct](https://numfocus.org/code-of-conduct),
+which we summarize as follows:
+
+We are committed to providing a friendly, safe and welcoming
+environment for all, regardless of gender, sexual orientation,
+disability, ethnicity, religion, or similar personal characteristic.
+
+Please be kind and courteous. There's no need to be mean or rude.
+Respect that people have differences of opinion and that every design
+or implementation choice carries a trade-off and numerous costs. There
+is seldom a right answer, merely an optimal answer given a set of
+values and circumstances.
+
+Please keep unstructured critique to a minimum. If you have solid
+ideas you want to experiment with, make a fork and see how it works.
+
+We will exclude you from interaction if you insult, demean or harass
+anyone.  That is not welcome behaviour. We interpret the term
+"harassment" as including the definition in the [Unacceptable
+Behavior](https://numfocus.org/code-of-conduct#unacceptable-behavior)
+section of the [NumFOCUS code of
+conduct](https://numfocus.org/code-of-conduct); if you have any lack
+of clarity about what might be included in that concept, please read
+that definition. In particular, we don't tolerate behavior that
+excludes people in socially marginalized groups.
+
+Private harassment is also unacceptable. No matter who you are, if you
+feel you have been or are being harassed or made uncomfortable by a
+community member, please contact one of the channel ops or any of the
+[MathJax](https://github.com/MathJax/MathJax) core team
+immediately. Whether you're a regular contributor or a newcomer, we
+care about making this community a safe place for you and we've got
+your back.
+
+Likewise any spamming, trolling, flaming, baiting, or other
+attention-stealing behaviour is not welcome.
+
+We also recommend that you read [discourse's
+rules](http://blog.discourse.org/2013/03/the-universal-rules-of-civilized-discourse/)
+for further suggestions on appropriate behavior.

+
+MathJax is an open-source JavaScript display engine for LaTeX, MathML,
+and AsciiMath notation that works in all modern browsers.  It was
+designed with the goal of consolidating the recent advances in web
+technologies into a single, definitive, math-on-the-web platform
+supporting the major browsers and operating systems.  It requires no
+setup on the part of the user (no plugins to download or software to
+install), so the page author can write web documents that include
+mathematics and be confident that users will be able to view it
+naturally and easily.  Simply include MathJax and some mathematics in
+a web page, and MathJax does the rest.
+
+Some of the main features of MathJax include:
+
+- High-quality display of LaTeX, MathML, and AsciiMath notation in HTML pages
+
+- Supported in most browsers with no plug-ins, extra fonts, or special
+  setup for the reader
+
+- Easy for authors, flexible for publishers, extensible for developers
+
+- Supports math accessibility, cut-and-paste interoperability, and other
+  advanced functionality
+
+- Powerful API for integration with other web applications
+
+See <http://www.mathjax.org/> for additional details about MathJax,
+and <https://docs.mathjax.org> for the MathJax documentation.
+
+## MathJax Components
+
+MathJax version 3 uses files called *components* that contain the
+various MathJax modules that you can include in your web pages or
+access on a server through NodeJS.  Some components combine all the
+pieces you need to run MathJax with one or more input formats and a
+particular output format, while other components are pieces that can
+be loaded on demand when needed, or by a configuration that specifies
+the pieces you want to combine in a custom way.  For usage
+instructions, see the [MathJax documentation](https://docs.mathjax.org).
+
+Components provide a convenient packaging of MathJax's modules, but it
+is possible for you to form your own custom components, or to use
+MathJax's modules directly in a node application on a server.  There
+are [web examples](https://github.com/mathjax/MathJax-demos-web)
+showing how to use MathJax in web pages and how to build your own
+components, and [node
+examples](https://github.com/mathjax/MathJax-demos-node) illustrating
+how to use components in node applications or call MathJax modules
+directly.
+
+## What's in this Repository
+
+This repository contains only the component files for MathJax, not the
+source code for MathJax (which are available in a separate [MathJax
+source repository](https://github.com/mathjax/MathJax-src/)).  These
+component files are the ones served by the CDNs that offer MathJax to
+the web.  In version 2, the files used on the web were also the source
+files for MathJax, but in version 3, the source files are no longer on
+the CDN, as they are not what are run in the browser.
+
+The components are stored in the `es5` directory, and are in ES5 format
+for the widest possible compatibility.  In the future, we may make an
+`es6` directory containing ES6 versions of the components.
+
+## Installation and Use
+
+### Using MathJax components from a CDN on the web
+
+If you are loading MathJax from a CDN into a web page, there is no
+need to install anything.  Simply use a `script` tag that loads
+MathJax from the CDN.  E.g.,
+
+``` html
+<script id="MathJax-script" async src="https://cdn.jsdelivr.net/npm/mathjax@3/es5/tex-mml-chtml.js"></script>
+```
+
+See the [MathJax
+documentation](https://docs.mathjax.org/en/latest/index.html#browser-components),
+the [MathJax Web Demos](https://github.com/mathjax/MathJax-demos-web),
+and the [MathJax Component
+Repository](https://github.com/mathjax/MathJax-demos-web) for more information.
+
+### Hosting your own copy of the MathJax Components
+
+If you want to host MathJax from your own server, you can do so by
+installing the `mathjax` package using `npm` and moving the `es5`
+directory to an appropriate location on your server:
+
+``` bash
+npm install mathjax@3
+mv node_modules/mathjax/es5 <path-to-server-location>/mathjax
+```
+
+Note that we are still making updates to version 2, so include `@3`
+when you install, since the latest chronological version may not be
+version 3.
+
+Alternatively, you can get the files via GitHub:
+
+``` bash
+git clone https://github.com/mathjax/MathJax.git mj-tmp
+mv mj-tmp/es5 <path-to-server-location>/mathjax
+rm -rf mj-tmp
+```
+
+Then (in either case) you can use a script tag like the following:
+
+``` html
+<script id="MathJax-script" async src="<url-to-your-site>/mathjax/tex-chtml.js"></script>
+```
+
+where `<url-to-your-site>` is replaced by the URL to the location
+where you moved the MathJax files above.
+
+See the
+[documentation](https://docs.mathjax.org/en/latest/web/hosting.html)
+for details.
+
+### Using MathJax components in a node application
+
+To use MathJax components in a node application, install the `mathjax` package:
+
+``` bash
+npm install mathjax@3
+```
+
+(we are still making updates to version 2, so you should include `@3`
+since the latest chronological version may not be version 3).
+
+Then require `mathjax` within your application:
+
+```js
+require('mathjax').init({ ... }).then((MathJax) => { ... });
+```
+    
+where the first `{ ... }` is a MathJax configuration, and the second
+`{ ... }` is the code to run after MathJax has been loaded.  E.g.
+
+```js
+require('mathjax').init({
+  loader: {load: ['input/tex', 'output/svg']}
+}).then((MathJax) => {
+  const svg = MathJax.tex2svg('\\frac{1}{x^2-1}', {display: true});
+  console.log(MathJax.startup.adaptor.outerHTML(svg));
+}).catch((err) => console.log(err.message));
+```
+
+**Note:** this technique is for node-based application only, not for
+browser applications.  This method sets up an alternative DOM
+implementation, which you don't need in the browser, and tells MathJax
+to use node's `require()` command to load external modules.  This
+setup will not work properly in the browser, even if you webpack it or
+bundle it in other ways.
+
+See the
+[documentation](https://docs.mathjax.org/en/latest/index.html#server-nodejs)
+and the [MathJax Node
+Repository](https://github.com/mathjax/MathJax-demos-node) for more details.
+
+## Reducing the Size of the Components Directory
+
+Since the `es5` directory contains *all* the component files, so if
+you are only planning one use one configuration, you can reduce the
+size of the MathJax directory by removing unused components. For
+example, if you are using the `tex-chtml.js` component, then you can
+remove the `tex-mml-chtml.js`, `tex-svg.js`, `tex-mml-svg.js`,
+`tex-chtml-full.js`, and `tex-svg-full.js` configurations, which will
+save considerable space.  Indeed, you should be able to remove
+everything other than `tex-chtml.js`, and the `input/tex/extensions`,
+`output/chtml/fonts/woff-v2`, `adaptors`, `a11y`, and `sre`
+directories.  If you are using the results only on the web, you can
+remove `adaptors` as well.
+
+If you are not using A11Y support (e.g., speech generation, or
+semantic enrichment), then you can remove `a11y` and `sre` as well
+(though in this case you may need to disable the assistive tools in
+the MathJax contextual menu in order to avoid MathJax trying to load
+them when they aren't there).
+
+If you are using SVG rather than CommonHTML output (e.g., `tex-svg.js`
+rather than `tex-chtml.js`), you can remove the
+`output/chtml/fonts/woff-v2` directory.  If you are using MathML input
+rather than TeX (e.g., `mml-chtml.js` rather than `tex-chtml.js`),
+then you can remove `input/tex/extensions` as well.
+
+
+## The Component Files and Pull Requests
+
+The `es5` directory is generated automatically from the contents of the
+MathJax source repository.  You can rebuild the components using the
+command
+
+``` bash
+npm run make-es5 --silent
+```
+
+Note that since the contents of this repository are generated
+automatically, you should not submit pull requests that modify the
+contents of the `es5` directory.  If you wish to submit a modification
+to MathJax, you should make a pull request in the [MathJax source
+repository](https://github.com/mathjax/MathJax-src).
+
+## MathJax Community
+
+The main MathJax website is <http://www.mathjax.org>, and it includes
+announcements and other important information.  A [MathJax user
+forum](http://groups.google.com/group/mathjax-users) for asking
+questions and getting assistance is hosted at Google, and the [MathJax
+bug tracker](https://github.com/mathjax/MathJax/issues) is hosted
+at GitHub.
+
+Before reporting a bug, please check that it has not already been
+reported.  Also, please use the bug tracker (rather than the help
+forum) for reporting bugs, and use the user's forum (rather than the
+bug tracker) for questions about how to use MathJax.
