If anyone can answer this question correctly and show me how you answered it to get the answer of -64, you will get a cookie... not really... a cyber cookie... now answer the question.
-7^2+4(3-9)/2+12/-4 = -64
DO IT AND YOU GET A CYBER COOKIE! Not really... just do it

Following the order of operations, first you do exponents and parentheses. Since the -7 is not in parenthesis, you square it and the square is negative:
-7^2 = -49
And then in parenthesis is 3 - 9 = -6
Since the next step in order of operations is to do all multiplication and division...
4 x -6 = -24. -24/2 =-12. 12/ -4 = -3
Last is addition and subtraction:
-49 - 12 - 3 = -64
