What is BIDMAS / BODMAS?

BIDMAS / BODMAS provides an acronym for the correct order to evaluate arithmetic.

B: Anything in brackets is evaluated first.

I/O: Any number with indices/ orders is evaluated next.

DM: Then divison and multiplication.

AS: Finally, addition and subtraction are evaluated in the order that it is written.

Note: The only difference between BIDMAS and BODMAS is the initial used to represent powers or roots. BIDMAS uses the term 'indices' and BODMAS uses 'orders' or 'powers of'.

How to use this resource

Use these BIDMAS questions as starter activities to refresh prior knowledge, or as structured practice following direct instruction on the order of operations. The three question types allow for scaffolded learning: begin with straightforward calculations to check understanding, progress to bracket insertion to develop strategic thinking, then challenge students with the combined task of adding both brackets and operators. The worksheet works well for independent practice, paired work, or as homework consolidation.
