Greg was adding numbers on a number line. He started on –5 and then he added –8. Greg wrote that the answer was +13.

Is Greg's answer reasonable?

A.
No, it is not reasonable because –5 + –8 = –13.

B.
Yes, it is reasonable because –5 + –8 = +13.

C.
No, it is not reasonable because if you add two numbers you will get a number that is greater than either of the two numbers.
