I need help adding/multiplying/subtracting integers?

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

there was this thing, liiiike

a positive x a negative = positive, or negative, or whatever.

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. =)

    If they are both the same (positive or negative) the result is positive. If they are different (negative*positive or positive*negative) then the result is negative.

    - 7 (-5) = 35

    -7 (5) = - 35

    7(5) = 35

    - 5 (7) = - 35
