15 + (7 - 10equals what?a: 13b: 36c: 12

Question

`15 + (7 - 10`equals what?a: 13b: 36c: 12

Answer 1

You solve in the parenthesis first aka “pemdas”

So that would leave us with 15+-3 which you can just drop the addition sign which would just be 15-3 and your answer would be C: 12.

Answer 2

`15+|7-10|`

we solve the absolute value first

`\begin{gathered} 15+|-3| \\ 15+3 \end{gathered}`

and do the sum

`15+3=18`
