Question

Why does -30 - - 50 equal 20? What steps are being done?

Answer 1

Step-by-step explain

1. 30-50=20

2. Two negatives equal a positive

So first you subtract 30 by 50 and get 20 then you look at the signs which are both negative. Meaning both of the negative signs become a positive. (-30)-(-50)=20

Answer 2

Two negatives equal a positive, so its just like subtracting 50 and 30, but your answer will be a positive.
