Order of Operations Practice for 11 Plus | BIDMAS Tips
19 October 2026
Why order of operations matters
Understanding the order of operations is essential for 11+ Maths. Without clear rules, calculations can give different answers. Using BIDMAS helps children work out sums in the correct sequence every time.
Key insight: BIDMAS stands for Brackets, Indices, Division and Multiplication, Addition and Subtraction, always in this order.
Common mistakes to avoid
Children often add before multiplying or forget to work out brackets first. These errors can lead to the wrong answer, even if every calculation is correct on its own. Practising with a clear method is key to building confidence.
Practice makes perfect
Regular order of operations practice helps children spot patterns and avoid common traps. Start with simple sums, then move on to questions with brackets and indices. Encourage your child to write out each step to keep their working clear.
