This little series of 5 videos is excellent. Seemed clear and straight forward to me, helped me over a sticking point. Thanks for for taking the time to record and upload..
This is as comvoluted as your ar[eggio technique. To begin with the prblem is subtraction of fractions and not addition as titled. Secondly, there is a much simpler way of solving such fractions - just cross multiply the respective denominators into the numerators, multiply the denominators and then simplify the entire expression as opposed to this overtly complex way of LCD etc.
Actually, I teach the cross multiplication techniqe in my mental algebra series (not on youtube). One should evetually learn the LCD method and as complicated as it is the students find it remarkably easy. My success rate is almost 100% on this topic which other teachers pulling their hair out. BTW, subraction is just a special case of addition.
This series really helped, totally easy to follow.

Thanks for creating this series. I've having trouble getting to grips with this, and I'm now about 90% of the way there thanks to you :)
