Think Math - Math Concept Map
Travel math concepts on a map
Free · Designed for iPad. Not verified for macOS.
802 math concepts from counting to calculus on one map, with worked examples, common mistakes and English concept videos. Tap a concept and see why it works.
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.
