Interactive visual tools for number theory and beyond

Watch prime numbers reveal themselves step-by-step as composites are eliminated from a visual grid.

Explore modular arithmetic on a clock face. See how step sizes create patterns and discover generators.

Visualize which numbers are coprime to n and understand the totient function through interactive exploration.

See the Euclidean algorithm in action — watch rectangles tile as the greatest common divisor emerges.

Plot multiple functions, zoom and pan, find roots and intersections — a Desmos-style experience.

Enter any polynomial equation and see every algebraic step, from factoring to the quadratic formula.

Enter data or upload a CSV. Instantly see mean, median, mode, std dev, histograms, and box plots.

Multiply, transpose, and find determinants — see how 2×2 transforms stretch and rotate a grid.

Approximate integrals with rectangles. Drag sliders and watch the error shrink as n approaches infinity.

Convert between binary, octal, decimal, and hex. See positional breakdowns and flip individual bits.

A full SymPy-powered CAS in your browser. Simplify, factor, integrate, solve, and more — with LaTeX output.
