A series of exercises designed to practice the correct order of operations: Brackets, Indices, Division, Multiplication, Addition, Subtraction (BIDMAS). There are a total of 336 questions, organised in to 5 exercises (Levels) containing 4 to 9 sets of 8 questions, ensuring there are plenty of questions to master this topic. Solutions are provided for every question. Level 1 introduced BIDMAS with sets of questions containing the four basic operations (addition, subtraction, multiplication and division) only. Level 2 adds brackets to the four basic operation. Level 3 requires to the student to add brackets to existing equations with the four basic operations to make them correct. Level 4 adds roots and indices to the brackets and the four basic operations. Level 5 concludes with nested brackets (brackets inside brackets). This topic corresponds to section N2 of the Edexcel GCSE Mathematics specification.

This worksheet contains 91 questions in 10 parts, practicing arranging numbers (positive and negative integers, fractions and decimals) in ascending and descending order.
