Three worksheet on the order of operations. The exercises aim to practice the correct order of operations: Brackets, Indices, Division, Multiplication, Addition, Subtraction (BIDMAS) and include two or more operations. Expressions with two or more operations are given and some terms are missing. One of the worksheets has elementary exercises and the other two have harder exercises. Detailed solutions are included.

Master the order of operations and critical algebraic thinking with this comprehensive, no-prep BIDMAS maths worksheets bundle featuring missing numbers and indices. Designed specifically for Key Stage 2 (KS2) and Key Stage 3 (KS3) secondary maths lessons, this print-and-go resource pack contains 3 completely separate, full-length practice worksheets packed with progressive calculations. A complete, step-by-step worked solutions guide is included for every single question to entirely eliminate your marking time and provide easy diagnostic scoring.

What is the Order of Operations (BIDMAS)?
BIDMAS is the essential mathematical hierarchy rule used to evaluate expressions correctly by prioritizing operations in a specific sequence: Brackets, Indices, Division and Multiplication (from left to right), and Addition and Subtraction (from left to right). This specific resource pack turns the traditional rule on its head by giving pupils the final answer and requiring them to apply BIDMAS logic in reverse to find the missing value.

What is Included in This 3-Worksheet Pack:
• Worksheet Pack 1 (40 Questions): Focuses on establishing core working-backwards skills, moving from basic linear maths to grouping brackets and introductory squaring and cubing expressions.
• Worksheet Pack 2 (40 Questions): Provides intermediate practice with a brand new set of integers, expanding on brackets and higher-value index rules (including expressions with large whole numbers like 10 cubed).
• Worksheet Pack 3 (40 Questions): Delivers an advanced tier of expressions featuring nested operations, challenging exponents (such as 2 to the 5th power), and properties of zero exponents (like 14 to the power of 0).
• Complete Step-by-Step Solutions Guides: Every single worksheet includes its own multi-page worked math answer key, showing the exact missing value filled inside each display box for quick and effortless marking or student self-correction.

Why Secondary Maths Teachers Love This Pack:
• Zero Planning Required: Simply download the high-quality PDF files, print the ready-made worksheets, and hand them directly to your class.
• Scaffolded Learning Flow: Questions naturally build in difficulty across each page, starting with basic linear arithmetic and building up to complex grouping symbols and multi-step index calculations.
