How do you multiply 2 digit numbers by hand?

Let's say you want to multiply 32 by 44. First, split each of them into their tens and ones. So, 32 becomes 30 (A) and 2 (B). 44 becomes 40 (C) and 4 (D). Multiply each of the numbers in the top line with both of the numbers in the bottom line. Simplify by carrying the zeroes outside if you have any tens. So, A x C = 30 x 40 = 100(3 x 4) = 1200 A x D = 30 x 4 = 10(3 x 4) = 120 B x C = 2 x 40 = 10(2 x 4) = 80 B x D = 2 x 4 = 8 Add them together, 1200 + 120 + 80 + 8 = 1408 Test it on a calculator 😁
