do the division operations first (from left to right) then the subtraction operation, or:
(81/9 = 9) - (16/8=2) = (9 - 2) = 7

To answer this you need to remember your order of operations:
P-Parenthesies
E-Exponents
M-Multiplication D-Division
A-Addition S-Subtraction.
So, you have to divide each of the two smaller equations
(81/9)-(16/8)
=
9-2
=
7
So you get 7 as your answer.
