Hilbert.ts is a TypeScript library for expression parsing, simplification, and MathML rendering. It was developed for Mathigon.org, an award-winning mathematics education project.

• Support for functions with subscripts (e.g. log_a(b)).
• Support for large operators (sum, product and integral).
• Parse ^ and _ operator from right to left (e.g. 2^2^2 == 2^(2^2)).
• CAS Expression simplification algorithms, equals() and same() methods.
• More tests, including visual tests for MathML.

First, install Hilbert.ts from NPM using

npm install @mathigon/hilbert

Now, simply import all functions and classes you need, using

import {Expression} from '@mathigon/hilbert'
