BIDMAS Practice — Free KS3 Order of Operations Worksheet

A free, printable KS3 worksheet on BIDMAS (the order of operations) without a calculator, with a full worked answer key. 16 questions graded easy to hard for Years 7, 8 and 9, building from multiply-first up to brackets, indices, same-rung traps and word problems.

The companion worksheet for the BIDMAS lesson. Work down the ladder — brackets, then indices (powers), then divide and multiply (equal priority, left to right), then add and subtract (also left to right). The questions build from "which comes first" up to brackets, indices, the same-rung left-to-right traps and two worded bills, and every one comes with a full worked answer so you can mark it together. No calculator needed.
