Question

If i have -52 balls and my mom had to give me 200 balls how much do i have?

Answer 1

you would have 142 balls because a negative plus a positive is postive

Answer 2

Since you have -52 and your mom gives you more, you would add 200 to -52. Or you could subtract 52 from 200. Either way, you will still get the result 148 balls. And so you will have 148 balls total.
