Does a negative number plus a negative number equal a positive or a negative number?

It could equal both a negagtive number or a positive number. To get a definite positive or negative you times or divide. Well in addition and subtraction negative plus a negative equals a bigger negative. Kinda like -4+-4 =-8, but in multiplication and division 2 negatives equal a positive. -2 times-2 =positive 4.
