Mathemagics 1

I found this video on Youtube and thought it would be useful. It shows effective ways to work out maths problems.
There are 11 videos altogether this is the first video.
Addition.
Make sure you stop and do some practice exercises when he asks you to. If you get stuck just skip to the part of the video that explains the part you need. The explanations are quite simple, but he does move fast so don't be afraid to rewind and watch parts again.



If you want to see it in full-screen click on the video then click on the button in the lower right side of the screen. (It is two squares on top of each other.)

Here is the link to all the videos.
