Question

mattfeury · Answer

7 - 28 + 11

anonymous · Answer

ive got that so far. -21+11 so would it be 10?

mattfeury · Answer

-10.

-21 + 11 = 11 - 21 = -10

anonymous · Answer

so total net yardage they got is -10?

mattfeury · Answer

yep. does that make sense?

anonymous · Answer

well dont i need to rearrange them?

mattfeury · Answer

addition follows the commutative property in that order doesn't matter: http://en.wikipedia.org/wiki/Commutative_property any order you add them in will be the same result.

anonymous · Answer

anonymous · Answer

i was thinking of putting them 11+7-28. but that would be way off. I see where you got -10. thanks soo much
