Here's a review of the original ‘cat’ book, which is ‘embedded in’ this algebra course.

For $1.00, you can purchase the pdf file of Chapter 4: Addition of Signed Numbers.
Images of what you get in this pdf file are shown below (scroll down a bit).

When you buy, you'll receive an email with a download link.
(So, check your email after checking out!)

The online lesson that goes with Chapter 4 is: As per my terms of use, you can't sell the pdf file (or make any profit from it) without my written permission. But, you can easily read it and print it. If you're a teacher—make as many copies (electronic or printed) as you need for your students. (Just be sure to preserve the copyright notices.)

If you have any questions, don't hesitate to contact me (Dr. Carol JVF Burns):
