You could always make the 8 an X and make it equal your answer to see if you got the right one, but I doubt most of CE can or would do algebra. But anyway, lets see if 16 is correct

8/2(2+2) = 16

Turn 8 into X

X/2(2+2) = 16

Simplify parentheses

X/2*4 = 16

Multiply fractions (because X/2 is a fraction)

(X*4)/2 = 16

Divide the numbers 4 and 2

2X = 16

Divide both by 2

X = 8

Since X = 8, 16 is correct.
