# Mathics3/mathics-core

An open-source Mathematica Kernel. This repository contains the Python modules for WL Built-in functions, variables, core primitives, e.g. Symbol, a parser to create Expressions, and an evaluator to execute them.

## What it is
Mathics3 Core is the kernel of Mathics3, a free open-source computer algebra system with Mathematica-compatible syntax. It provides Python modules implementing Wolfram Language built-in functions, a parser for expressions, and an evaluator, runnable via a simple command-line REPL.

## Use cases
- evaluate symbolic math expressions from the command line
- run Mathematica-compatible code without a Mathematica license
- embed a computer algebra engine in Python applications
- solve algebra and calculus problems symbolically
- learn the Wolfram Language for free
- script mathematical computations using WL syntax

## When to choose
- you need a free, open-source alternative to Mathematica
- you want Mathematica-compatible syntax and built-in functions
- you need a programmable CAS kernel embeddable in Python
- you want a lightweight CLI for symbolic computation

## When to avoid
- you need full Mathematica functionality, performance, or notebook interface
- you require a polished GUI or web frontend out of the box
- you need guaranteed numerical parity with Wolfram's kernel
- you need a commercially supported CAS

## Facets
- artifact type: library
- maturity: active
- function: interpreter, parser, math, cli
- domain: mathematics, programming-languages, education, developer-tools
- platform: python, cross-platform, cli
- tags: computer-algebra-system, wolfram-language, mathematica-compatible, symbolic-math, cas
