Math you can touch, play and understand

From your first numbers to calculus. Every idea comes with a simulation you can play with, a real-world example, a game, and the story of the scholar who discovered it.

Open the full learning path

Learn math by doing, not memorizing

Simulations and 3D

Drag, slide and rotate: build fractions, balance equations, spin a 3D solid, roll a ball down a curve.

Real-world examples

Every lesson shows where the idea is used: cooking, sport, maps, money, games, science and engineering.

Games and challenges

Speed sprints, clock challenges, balance puzzles and target games turn practice into play.

The story behind the math

Meet al-Khwarizmi, Euclid, Hypatia, Brahmagupta, Newton, Noether and many more.

A path for every level

Five stages from age 5 to university, and a personal learning path that starts where you are.

Three languages

Every lesson, quiz and simulation in English, French and Arabic, with full right-to-left support.

Try it now: play with a function

Move the sliders and watch the graph change. This is the heart of algebra: a rule that turns one number into another.

Mathematics has a story

From tally marks on bones to the algorithms in your phone, thousands of people across every culture built the math we use today.
