It's basically saying $80 - 63$ $80-63$ , so the answer is $17$ $17$ .

To put it visually:

$< -63 ... 0 ... 80 >$

Pretend that's a timeline. They want you to ADD -63 to 80, so you would count down from -63 to the right of the timeline--and you would land on 17.

So $80-63=17$

How do you evaluate 80+ ( - 63) 80+(−63)80+ ( - 63) ?
