Thank you I just didn't know if it was supposed to be a negative number or not. My math that I have is really confusing.

You're welcome.
Think about a number line.

When you take 12 from 12, you arrive at 0. Then you have to go to the negative side of the line.
Consider money. If you have $12 and buy something for $12.90, you have to borrow 0.90 to make your purchase.
