Answer 1

OK, every one of them has an arrow going left, from 0 t o-8, correct?

Remember "left". if we are counting negative numbers, we count left. if we are counting positive numbers, we count right.

Answer 2

There is also a subtraction sign in the problem, so I have to talk about subtracting and adding for a sec.

Answer 3

So to subtract -2 [ the "-(-2)" part ] you go from the end of the "-8 arrow" two units in the opposite of -2.
