My son's math homework asks him to find each product by factoring the tens. 6 x 2, 6 x 20 and 60 x 20. There is no explaination in the book..can you help?

Answer 1

Factoring the tens is a technique for mental multiplication which relies on the fact that 10*n, for any real number n, is easy to compute.

6*2 = 12 is a memory value.

6*20 = 6*2*10 = 12*10 = 120
60*20 = 6*10*2*10 = 12*10*10 = 1200
