-43 + 17 is a very easy problem to solve.
Let's remember the differences about adding or subtracting a positive or negative 17 to this problem.
adding a positive: -43 + 17 = -26
adding a negative: -43 + -17 = -60
if we were subtracting, the problem would turn out like this:
subtracting a positive: -43 - 17 = -60
subtracting a negative -43 - -17 = -26
When doing problems like this, you have to remember the steps so you won't get confused when the problem becomes difficult further on.
