About
About Math Playground
A free, interactive place to learn mathematics by touching, dragging and playing with the numbers — built and maintained by one person who loves this stuff.
What this site is
Math Playground (math.calcstack.co) is an educational website covering numbers, algebra, geometry, calculus, physics, computer graphics, data, money, puzzles and games. Almost every page has an interactive widget — a slider you can drag, a shape you can spin, a simulation that runs — because the fastest way to understand a piece of maths is to play with it.
Who makes it
It's a personal project by Awais Shah, a software engineer. The lessons, explanations and interactive widgets are written and built originally for this site. It is not affiliated with any school, publisher or other “math is fun”-style website.
Our content
- Original. Lesson text, examples and widgets are written specifically for Math Playground.
- Free. Everything on the site is free to read and use. The site may display ads (see our Privacy Policy) to help cover hosting costs.
