Question

Why can a subtraction problem be rewritten as an addition problem without changing the outcome?

Answer 1

because of the commutative property of addition

i.e.
2 + (-3) = -3 + 2

Answer 2

if you consider that there is no such thing as subtraction, then it all works out fine.

adding the opposite is equivalent to "subtraction"
