Question

-48+30=-78 Explain what I did to get this answer. What is the correct answer, and explain how you got it

Answer 1

Where you went wrong:

Instead of adding 30 to -48, you subtracted 30 from -48 and you ended up with -78.

Correct answer with explanation:

-48 + 30 = -18

Simply add 30 to -48, or a more intuitive would be to subtract 30 from positive 48 and then remembering the problem was -48 + 30 so adding the negative sign to get -18.
