How many pre-Algebra textbooks do you suppose are in use world-wide at this particular point in time? If you guess less than 100 you are WAY off.
So you pose that question as if by some sort of clairvoyance one of us will know what textbook you have and to which you are referring and then we can just reach up onto the shelf where we have a set of all of the pre-Algebra texts (at roughly $100 each for an investment of over $10,000 per tutor just for pre-Algebra).
Go back and read the instructions for posting questions on this site. If you can't understand them, print them out and take them to your English teacher who may perhaps be able to explain them to you in simpler terms. When you get it, then start following the instructions.
