15 x 15
what is 15 x 15
What -- you can use a computer, but not a calculator?
5*3*5*3 =25*9 = 25*8 + 25*1 = 200 + 25 = 225
Or maybe
15 ( 10 * 5) = 150 + 75 = 200 + 25 = 225
15 ( 10 * 5) = 150 + 75 = 200 + 25 = 225
nah 15* 5 is too hard
(10 + 5) 5 = 50 + 25 = 75 So I got it after all.
150 + 50 +25 = 200 + 25 = 225
(10 + 5) 5 = 50 + 25 = 75 So I got it after all.
150 + 50 +25 = 200 + 25 = 225
