Question

|-3 + 15| what is the sum (answer) ? I think it is 12 but my friend thinks it is 18. Who is right?

Answer 1

I do believe it is 12 as well considering the fact that it's negative three and not positive. If it was a positive three then maybe it would be 18.

Answer 2

Nooo -3+15=-12 but since it's absolute value it is 12
