The POWERS between the BRACKETS have to be worked out first!
Following the PRIORITY rules we get:
7 x ( 36 - 32) = 7 x 4 = 28
A common mistake would be:
7 x ( 12 - 10 ) = 7 x 2 = 14 In this case you've done 6 x 2 and 2 x 5 instead of
calculating POWERS! Another common mistake:
= 36 - 25 = 7 x 11 = 77 because here '7' disappeared for a while!?
