Question

CA High School Exit Exam question: (no joke)
if -n = 3, what is n?
A. 3
B. -3
C. 0
D. Not enough information.

Answer 1

The equals sign says both things are equal. So if we imagine it says 10=10 we can divide both sides by 5 to get 2=2. Similarly we can divide both sides of -n=3 by the same number to find out what n equals.

Answer 2

thanks. I know how to do it. Isn't it so sad how dumb some Californians are?

Answer 3

Nah, I live in Texas, it's worse!
