In this lesson
In this video you'll learn about order of operations: brackets, powers, roots and BIDMAS for GCSE Maths, with worked examples and the mistakes examiners report. By the end you'll be able to evaluate an expression involving brackets, powers, roots and the four operations in the correct priority order, including entering it correctly into a calculator.

For teachers
This GCSE Maths lesson teaches order of operations: brackets, powers, roots and BIDMAS. By the end, students should be able to evaluate an expression involving brackets, powers, roots and the four operations in the correct priority order, including entering it correctly into a calculator. It works through two worked examples and the mistakes examiners report.
