Its core design principle is that legal moves are always possible and illegal moves are impossible — equations are transformed only via rewrite rules, ensuring every reachable state is valid by construction. Conditional soundness handles edge cases like division by zero through first-class Assumptions that travel with the equation. The library includes ~25 built-in rules for linear equations, fractions, exponents, and quadratics; immutable ASTs with stable node IDs for animation; exact bigint rational arithmetic (no floating point); move enumeration with gesture anchors; and layout geometry utilities. It powers a gesture-based algebra app for iOS and Android, with the engine released under MIT. ## Full article daily.dev links to this article rather than hosting it.
