Question

alright, so i learned all this last year in the seventh grade, but i've forgotten all of it.

Or whatever....

I just need to know if you get a positive or negative when you multiply two negatives, and a positive or negative when you multiply a positive number and a negative number. So thank you. yeah, okay. sorry this question was soo confusing. =)
