Intro to Combining Like Terms

Intro to Combining Like Terms

This is an individual lesson that you will go through on your own. It should be somewhat of a review. You will go through the lesson and then at the end be given questions to see how you have learned. Please pay attention and do your best. If you do well, we will not have to do a notes lesson over it :)
