Answer: it’s helps to write a subtraction problem as an addition problem becuase then solving the problem gets easier

You can write a subtraction problem as an addition problem by flipping the terms.

For example:

3-2 is the same as -2+3

15-7 is the same as -7+15

30-15 is the same as -15+30

Subtracting a positive is the same thing as adding a negative. Subtracting a negative is the same as adding a positive. Sometimes it's a little easier to do it that way.
