Math API
A full math engine as an API, powered by mathjs. Evaluate any expression — arithmetic, hundreds of functions (sqrt, sin, log, gcd, factorial, combinations, …), constants (pi, e), complex numbers, matrices and number theory — with optional precision control (e.g. 2+3*sqrt(16) → 14, pi at 5 digits → 3.1416). Take the symbolic derivative of an expression with respect to a variable (x^2+3x → 2*x+3), and simplify algebra (2x+3x → 5*x). No formula libraries to bundle, no maths to reimplement: send an expression, get the answer. Ideal for calculators and STEM education apps, spreadsheet and form logic, quiz and homework tools, engineering and data dashboards, and any product that needs reliable server-side computation.
