Square of 6
6 squared equals 36. Squares appear in area calculations, the Pythagorean theorem, and statistics (variance uses squared distances).
Squares obey quiet rules. Divided by 9, a square only ever leaves 0, 1, 4 or 7 — 0 here. On the last digit, squares end only in 0, 1, 4, 5, 6 or 9, and 6 fits. Between its neighbors, 25 sits 11 below and 49 sits 13 above — the square ladder widens by exactly two at every step. Double the base and the square quadruples: 12² = 144, which is 4 × 36. Two anchors most worth memorizing in this range are 12² = 144 and 15² = 225 — the odd-step rule above is why knowing them pays off, because from any anchor the next square is one step along this page's ladder.

Frequently asked questions
What is 6 squared?
6 squared is 36, because 6 × 6 = 36. The exponent 2 is why it is written 6².
What is 7 squared, next to 6²?
7² = 49, which is 13 more than 6² = 36. Each step up adds double the base plus one.
Where do squares show up in real problems?
Area of a square with side 6, distance in the Pythagorean theorem, and variance in statistics all use squared values.
