The whole math canon in one Kluu. This 728-page reference book gathers more than 600 formulas from kindergarten through AP Calculus and AP Statistics into 16 clear chapters. Every formula comes with a visual explanation, worked examples at easy, medium, and hard levels, and speed-math tricks, plus a full A to Z index so students can find what they need quickly.

Inside: arithmetic and number theory, all algebra and quadratic formulas, geometry (area, perimeter, surface area, volume, distance, midpoint), trigonometric identities, exponential and logarithmic rules, sequences and series, probability and statistics, plus the formulas tested on the SAT, ACT, ISEE, and AP exams. Cross-referenced, labeled with when to use each one, and small enough to live in a backpack.

The reference your child will reach for the night before every test.
