A common use for algebra is to make rules about certain situations, and using pronumerals and variables to allow these rules to work for a variety of different circumstances. It is important that we understand how to set up these rules. It is quite difficult for me to teach you how to do this using this blog, so what I have done is uploaded some pages from a text book that explain what to do quite well. They have some worked examples as well which are handy to look at.
This document can be found by clicking here. Read through this and use the worked examples to help you work through the new worksheet, which has been uploaded to the "Worksheets" tab. This new worksheet looks like a lot of work, but once you get the hang of it, it will not take you long at all. Make sure you check your answers with the answers provided. I will say that the answer for questions 1 in section 5.5 does have an error in it, but the rest of the answers are correct.
As always, if you have any questions feel free to comment on this post, or email or chat to me in person.
