Square of 24
24 squared equals 576. 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, 529 sits 47 below and 625 sits 49 above — the square ladder widens by exactly two at every step. Double the base and the square quadruples: 48² = 2304, which is 4 × 576. 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.
