Can you help me?

e.mccormick · Answer

I have no clue what it means to use a chip board.

calculusxy · Answer

So it's basically a board with two kinds of chips (black and red). The black chip represents the positives (1) and the red chip represents the negatives (-1).

calculusxy · Answer

If you do know about zero pairs, it's when you add a number along with the opposites, you always get zero, e.g. 1+(-1)=0 .

calculusxy · Answer

So you cancel those out.

I mean if you do want to learn, you can go to http://www.basic-mathematics.com/modeling-integers.html

e.mccormick · Answer

Well, then it should be pretty easy to get things correct.  It is just seeing what cancels and what is left.
