(-18 - 17= -35)
Sorry but the scaling doesn't hold when I send the solution but try to get the idea of a negative numbered line.
-35 -30 -25 -20 -15 -10 -5 0 +3
|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|-|
* *
(-35)------------ -18 ------------- (-17) ----------- -17 ---------------
Starting from zero & going to the left on a numbered line 17 unite, you are at (-17).
Going another 18 units to the left, you are at (-35).
-17+(-18)=-35
17-18=-35
