Okay I am not 100% sure because that is an extremely confusing question. But here is what I got.

Two different ways to find the difference for 12-3

Gennadij [26K]

For this case we have:

way 1:
Common factor 3 in the expression:
$12-3 = 3 (4-1)

12-3 = 3 (3)

12-3 = 3 (9)$

Way 2:
Write the number 12 as the sum of 4 times 3:
$12-3 = (3 + 3 + 3 + 3) - 3
$
Then, for associative property:
$12-3 = 3 + 3 + 3 + (3 - 3)

12-3 = 3 + 3 + 3 + (0)

12-3 = 3 + 3 + 3

12-3 = 9$
