Answer:
It could be +2 or -8
Step-by-step explanation:
To get +2 you would have to do a + b. Which would even up too -3 + 5. that equals +2 and if you flip it you get the same thing b + a.
To get -8 you have too subtract instead of adding. So you would do a - b. That would be -3 - 5. and when you subtract negatives you must Keep, Change, and Flip (KCF) the problem. You would Keep -3, then you Change the sign which means from subtraction to addition so - to +. And the last step is to Flip it which means to flip the number to the opposite sign +5 would go to -5. So in the end you would have -3 + -5 which gives you -8.
