Question

Greg was adding two numbers on a number line. He started at +4 and then he added –6. He wrote that his answer was –2.

Is Greg's answer reasonable?









A.
No, it is not reasonable because when you add two numbers you get a number greater than either of the two numbers. The answer is +10.







B.

No, it is not reasonable because you subtract the smaller number from the larger number to get +2.








C.

Yes, it is reasonable because if you start at +4, you will move 6 spaces to the left to get –2.
