What is MathCodes?

MathCodes is an open project designed to help you learn math through computation, visual intuition, and curiosity. Every problem is validated with Python—not prose—and follows a transparent specification.

📐 Visual Explanations

Understand math through diagrams, graphs, and interactive examples.

📘 Structured Notes

Explore carefully written Python notes on topics like calculus, differential equations, statistics and more.

💡 Code-Driven Learning

Solve human-authored problems by writing Python only—each submission is sandboxed and validated against deterministic tests.

Daily Code-Arrange Challenge

A Math Wordle for logic and math intuition. Drag shuffled Python blocks into the right order, tap Run, and see the pre-stored output. No sandboxing, no backend—just thinking like a mathematician with code.

  • Fresh puzzle every day with instant feedback.
  • Zero backend compute: static JSON + client-side drag-and-drop.
  • Shareable wins that build streaks and community momentum.

Today's teaser

Arrange the blocks to evaluate limx→0 sin(x)/x

Shuffled blocks

return result
result = sp.limit(expr, x, 0)
x = sp.symbols('x')
expr = sp.sin(x) / x
import sympy as sp

Clicking Run shows the stored output: 1.0
