GCSE Maths revision tutorial video.

In this video I used commas to separate the "leaves". This is not necessary, as each leaf is only one digit. However, in the GCSE you will not be penalised for adding commas.

For you guys who understand the first half and are confused about the other half (The Key), all you need to do is draw a box and indicate it called "Key" and write a number, for example if you want to write 10 you put 1|0 = 10 or 2|3 = 23, it can be anything but must be in that genre.

why would i need a key and how do you decide what number is the key?
