Sample Data

Front Calculate \(57^2\) using the Multiple of 100 base method.
Back \(57^2 = (50 + 7)^2 = 50^2 + 2(50)(7) + 7^2 = 3249\).
Front Find \(614^2\) using the \((a + b)^2\) formula.
Back \(614^2 = (600 + 14)^2 = 600^2 + 2(600)(14) + 14^2 = 360000 + 16800 + 196 = 376996\).
Front Compute \(78^2\) using the Base 100 method.
Back \(78^2 = (80 - 2)^2 = 80^2 - 2(80)(2) + 2^2 = 6084\).
