hey, I was solving this problem: ** x ** - * = 120
the possible answers are: 11 x 11 - 1 = 120 and 10 x 12 - 0 = 120
They said that the best way to solve this is by questioning which numbers between 120 and 129 have two 2-digit multiplicands, but I really didn't understand this technique, can anyone exemplify it better or explain it to me?
