Mathy
What Mathy is
Mathy is a free, open-source Linux tool for solving algebra and other math problems while showing solution steps. Its computer algebra system parses text into expression trees, then manipulates and evaluates them with user-defined rules that preserve expression value. The interface can display those trees in a compact layout without overlapping branches. You can use built-in learning environments or create your own by specifying actions, problems, rewards, and win conditions. Mathy Envs supplies customizable reinforcement-learning environments with valid-action masks, feedback for individual actions, and easy, normal, or hard difficulty variants. A wrapper registers these environments with Gymnasium. The command-line interface simplifies polynomial expressions, creates randomized problem lists, and uses a swarm-planning algorithm to select intermediate steps. Installation uses `pip install mathy` and requires Python 3.6 or later. Python type hints support IDE autocompletion and linting.
