## What it is
A JavaScript library for building, displaying, and solving algebraic equations, expressions, and fractions. It supports linear, quadratic, cubic, and quartic equation solving and can output LaTeX.

## Use cases
- solve algebraic equations in javascript
- build and simplify algebraic expressions programmatically
- work with fractions and reduce them automatically
- solve quadratic equations in node
- render equations as latex
- teach algebra with step-by-step expression manipulation

## When to choose
- you need lightweight symbolic algebra (fractions, expressions, equation solving) in JavaScript
- you want to run in the browser or Node with no dependencies
- you need LaTeX output for equations

## When to avoid
- you need a full computer algebra system (calculus, polynomials of high degree, symbolic integration)
- you need actively maintained software with recent releases
- you need numeric-heavy linear algebra or matrix computations

## Facets
- artifact type: library
- maturity: maintenance
- function: math
- domain: mathematics, education, developer-tools
- platform: browser
- tags: algebra, equations, fractions, expressions, latex, symbolic-math, nodejs, javascript
