What plus 4 is equal to -2.8?  Or, what minus -2.8 is equal to 4?

6.8+4=10.8.  You want something in the negatives ;)

No, no, you're fine! :)  Negative numbers can be confusing sometimes.  If you have trouble with an equation, just set it up differently or plug in the other answers to see which one fits.
