*Solve math problems. Show your work. Contribute new solution types.*

**Documentation**: https://mathy.ai

**Source Code**: https://github.com/justindujardin/mathy

## Features¶

**Computer Algebra System**: Parse text into expression trees for manipulation and evaluation. Transform trees with user-defined rules that do not change the value of the expression.**Learning Environments**Use built-in environments or author your own. Provide custom logic and values for custom actions, problems, timestep rewards, episode rewards, and win conditions.**Visualize Expressions**: Gain a deeper understanding of problem structures and rule transformations by visualizing binary trees in a compact layout with no branch overlaps.**Free and Open Source**: Mathy is free because educational tools are important and should be accessible to everyone.**Python with Type Hints**: typing hints are used everywhere in Mathy to help provide rich autocompletion and linting in modern IDEs.

## Requirements¶

- Python 3.6+

## Installation¶

```
$ pip install mathy
```

## Try It¶

Let's start by simplifying a polynomial problem using the CLI:

### Simplify a Polynomial¶

```
$ mathy simplify "2x + 4 + 3x * 6"
```

Mathy uses a swam planning algorithm to determine which intermediate steps to take to achieve the desired solution.

The output will vary, but it might look like this:

### Generate Input Problems¶

Mathy can generate lists of randomized problems. Rather than forcing users to create solutions, Mathy uses environment-specific functions to determine when a problem is solved. In this way, users don't need to know the answer to a question they generate.

```
$ mathy problems poly
```
