Question

Where do I put the parentheses in 21-8-6=7

Answer 1

around 21-8 so the equation would look like this (21-8)-6=7

Explanation:

you do this because if u put the parentheses around 8-6 you would get 21- (8-6)= 19 because 21 - 2 = 19 so you have to put them around 21-8 to get the right answer
