Before we start, we need to clear up if it's BIDMAS or BODMAS. It's clearly answered in the video and then I take some time to explain how it is used. There are lots of examples which show, not only how to use BIDMAS/BODMAS but how to use it with negative numbers. The rest of the video looks at how we can use the work from Year 7 algebra alongside the new work on negative numbers and BIDMAS. This is the beauty of mathematics! There are lots of worked examples all explained in an easy to understand way.
There are no current errors with this video ... phew!
