The Maths Video Section

Technical Stuff: The videos are wmv files which means that they run on Windows Media Player. This is shipped with Windows 7, 8 and Vista. You can download it for free from here. We have started to upload MP4 files as well but you will notice the size difference. It is up to you which you choose to use.

These videos are designed to provide a reminder of how to carry out specific operations. If you have forgotten how to do something, load the video and see if you can remember. Once you have watched the video a couple of times, you might want to try out the maths spreadsheets to help you to get the idea. Most of these files are large and so will take a long time to download, even if you have broadband. Provided you don't clear your cache, it should be quicker the second time you run it. The number in the second column indicates the approximate size in megabytes of the video file and in parenthesis, I have put the duration of the video.
