Hi all,
I've been studying math quite a bit lately, as it has been about 7 years since I have done much. I have been using the study guides and resources everyone has mentioned on here. Today I was looking at the ASTB-E practice questions provided by the actual website, and aside from a log question, and the one below, I got the rest right. I might be having a brain lapse on order of operations, but can someone explain to me how the question below equals 20 as demonstrated on the answer key?
-2^-2[(-4-6^0)(5-3^0)]/|-6|-[-(-2)]
Your help would be greatly appreciated. Thanks!
Nate
