Math
So since it is traveling 20 mph, but the current is going 8mph, the difference is 12mph that the boat is really traveling. 60mph / 12mph = 60/12 = 5 hours to get up the river.

Math
In mathematics, the additive inverse of a number a is the number that, when added to a, yields zero. So it would be negative a. -from wikipedia So, additive inverse of 7 is -7 this statement is true by definition

closure propery
Closed under multiplication means that any member of the set times any other member of the set (including itself) yields another member of the set. We have the combinations, -1 * 0 = 0 -1 * 1 = -1 -1*-1 = 1 0*0 = 0 0*1 = 0 1*1 = 1 All results are from the set, so it indeed is ...

Oh...I see

You can thank Ms. Sue too :D

Probably not ... counterfeit things are fake replicas of the real thing. its not really copying on a smaller scale, so its computer representation.

Math
False. Let the number being subtracted be x. Let the number subtracting x be y. So we get y-x. But since x is negative, we get double negatives, and thus we move more to the right, more positive.

Math
I agree with Ms. Sue.

Uh...I meant like post another entire question, not like a whole chain of them.
