Can you turn a subtraction problem into an addition problem?

Answer 1

Yes, since adding a minus is the same as subtracting a plus; for example

5 - 3 = 2

5 - (+3) = 2

5 + (-3) = 2

Answer 2

Yes, you can add the inverse additive. For example:* To subtract 3 is the same as to add -3.

* To subtract -5 is the same as to add 5.
