New GCSE Maths Syllabus

Algebra - Using BIDMAS. Made Easy!

It is very important to learn what BIDMAS stands for and how and when to use it. BIDMAS is a key part of the new GCSE maths syllabus and is a process you should be remember.

If you’re faced with an equation in the exam, you’ll need to know in what order you should go about solving it. You need to know what parts of the equation need to be solved first and which should be left to the end. This is where BIDMAS comes in.

BIDMAS stands for:

B - Brackets

I - Indices

D - Divide

M - Multiply

S - Subtract

This is the order you should follow when solving an equation.

Let’s go through an example: (59 + 9) - 5 x 32

B - first we do the brackets to get: 68 - 5 x 32

I - then we work out the indices: 68 - 5 x 9

D - next we do any dividing: in this example there is none

M - then we multiply to get: 68 - 45

A - now we do any adding: in this example there is none

S - and finally, we do any subtracting: 23
