My little brother needs help with this:

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

Give a real-world scenario where this might be modeled.

It can be done so in simple daily calculations such as calculating how much money you'll have after after you spend some.

$100- $52= $48

and if you switch it into an addition problem you will get

$100+(-52)= $48,


Or you can get $48 + $52 = $100
