I can do 8th grade math! Kinda...

You'd think that after spending 12 years getting a BA in math, I would have no problems with a test that purports to tell you if you could pass 8th grade math. And sure enough, I got 10/10—but that was only because I guessed right on this question:
-7 is:

a. Irrational
b. An integer
c. A whole number
d. A prime number
I hate it when test creators don't carefully check their tests. Depending on how you define "whole number", either b or c could be correct. According to the Wikipedia (and my memory, which is even less reliable), a whole number can be either a positive integer (1, 2, 3, ...), a nonnegative integer (0, 1, 2, ...), or any integer (... -1, 0, 1, ...).

This isn't, however, as bad as the questions from Thailand's test of English I posted a while back.
