Think Math

Think Math is a concept explorer that lays out every math concept from elementary through high school on a single map. 802 concepts cover the whole curriculum, from counting to calculus.

Narrow things down in three steps - area, unit, concept - to find what you need fast. Fractions, roots, exponents and sigma notation are typeset properly, just like a textbook. Concepts are linked to short YouTube concept videos, so you can read an idea and then watch it.

We hope math stops being something to memorize and becomes a journey of thinking, all on a single map.
