What's included
- Ready-to-use worksheet with three sets of questions to practice the order of operations based on BIDMAS or BODMAS. Available as a free printable PDF or an editable Word doc.
How to use these BIDMAS / BODMAS questions
The exercises ask students to use BIDMAS to: calculate correct answers, insert brackets or insert brackets and mathematical operators. Questions feature addition, subtraction, multiplication and division. They range from straightforward to challenging and are suitable for developing maths skills at KS3 and GCSE.
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 'orders' or 'powers of'.

Sample questions from the worksheet:
Exercise A: Evaluate
1. 2 + 3 x 5 2. 5 x 2 + 6 3. 20 – 2 x 4
Exercise B: Insert brackets to make each calculation correct. We only add brackets when needed so some questions will not need brackets, which ones?
1. 14 + 1 ÷ 3 = 5 2. 18 ÷ 6 + 3 = 2 3. 20 ÷ 4 + 1 = 6
Exercise C: Insert the correct symbols: ( , ) , + , - , x , ÷ to make each calculation correct.
1. 10 2 3 = 16 2. 30 2 3 = 24 3. 30 2 3 = 18
