Video: Adding and Subtracting Algebraic Fractions
I came across this video from a Singapore tutor in my browsing today. It explains how to simplify an algebraic fraction problem. Interestingly, I solved a similar problem with my one of my algebra students last week. I like how this blogger breaks the steps down, but I would like her to explain more why the students made the mistake they made in the beginning. Quick quiz: do you know why? What is their misconception?
