A calculator that gives exact answers.
A symbolic calculator for algebra, calculus, matrices, sets, differential equations and graphing. It keeps answers exact (√2 stays √2, π stays π) and shows the decimal alongside. Built as a desktop app in Python. This page runs that same Python engine right in your browser, so go ahead and try it.
Exact mathPowered by sympy, so answers are simplified, not rounded.
Real graphsCurves, regions, polar, parametric and slope fields with intercepts marked.
Standard tierSeveral connected steps and a real interface. $50 to $75 as a client project.
The first load downloads Python and its math libraries (around 30 MB), so give it a few seconds. After that it is quick.

Things you define (v = 3, f(x) = x^2, matrices, sets) show up here.
What went into it
Small tool, real engineering.
- A parser that understands calculator shorthand:
2pi,sinx,f',1int5(x^2) - Exact solving, derivatives, integrals, limits, sums and differential equations
- Matrices with row operations, inverses, determinants and RREF
- An interactive graph that finds intercepts and crossings on its own
