I think it is question 67. It is wrong. The use of the order of operations isn't correct. XZ+XY/Z^2 X=6 Y=(-2) Z=3

(6*3) + (-12/9) that is the proper way to do that problem. You have to divide before you can add. The problem has you 18 + (-12) the divide by 9.

I know it looked goofy but by looking at giving answers there should have been a parenthesis around the addition so it could be done before the division.

The parenthesis weren't in the problem when I took the test. If they were there would be no problem.
