Explain every move.
mathphp/mathphp-explaining turns an AST evaluation into ordered, translated steps with substitutions, partial results, and source spans.
Package catalogue
One core.
Three ways to extend it.
The evaluator stays free and focused. Add the private package that gives your users a lesson, a picture, or quantities with real units.
Make the result visible.
mathphp/mathphp-visuals produces portable chart data and accessible SVG fallbacks for plots, matrices, calculus, and statistics.
Keep units attached.
mathphp/mathphp-units parses quantities such as 2m * 6 + 200cm, normalizes compatible dimensions, and returns a formatted result.
Built as additions.Install the free core alone, or load one or more private packages when your product needs them.Read distribution notes →
