Question

How would I subtract 13-(-4) ?

Answer 1

when you have two negatives next to eachother they counteract, so you would actually add in this case.

Answer 2

Oh? so 13 + -4?

Answer 3

when you have 2 negatives it turns into addition. 13+4

Answer 4

Oh ok, so you're basically taking away the negative because of the subtraction?

Answer 5

What about -8+-4?

Answer 6

a plus in front of a negative does not change that sign, you would just disregard it and subract -8-4

Answer 7

I got -12...is that correct?

Answer 8

yes :) you got it

Answer 9

Awesome! Thanks!!

Answer 10

look at it this way:
++ will always be addition
+- or -+ will always be subtraction
-- will always be subraction
