The book was a private scan request from a Bookshare member but it is a really neat book. E., I think I will go ahead and write out the squared instead of using ^ then and do the divided by instead of / since I have already done the first dozen pages that way. I don't expect to have this book done for a couple of weeks but I'm hoping my son will be interested in the book since it is so practical and they seem to be doing a lot of these same concepts in his 4th grade math class.
