Integer Operations & PEMDAS Worksheet + Answer Key | 7th 8th Grade Math

A worksheet on addition, subtraction, multiplication and division of integers. The exercises include one or more operations between integers. There are 48 exercises and solutions are included.

Looking for a comprehensive, no-prep practice worksheet to help your pupils master operations with integers and the algebraic order of operations?

This massive 48-question practice resource is specifically engineered to build ultimate mathematical fluency. It features a perfect, scaffolded progression of skills—starting with simple single-operation tasks (addition, subtraction, multiplication, and division) and smoothly transitioning into complex expressions that require the order of operations (BIDMAS/BODMAS) with positive and negative numbers.

Perfect for Key Stage 2 (KS2) advanced extension, Key Stage 3 (KS3) core instruction, or as a critical GCSE foundation revision packet at the start of the term!

What’s Included:

• Pages 1–3 (48 Scaffolded Questions): A clean, beautifully organized layout featuring large, clear problem boxes that give pupils plenty of space to write out their calculations.
  Questions 1–14: Core single-operation problems focusing on adding, subtracting, multiplying, and dividing integers.
  Questions 15–28: Progressively challenging single operations, including double-negative distribution and larger divisors.
  Questions 29–40: Multi-step integer calculations introducing long chains and multiplication with three or more factors.
  Questions 41–48: Advanced expressions requiring strict compliance with the order of operations (brackets, fractional division groups, and multiple negative interactions).
• Full Step-by-Step Answer Key: Pages 4–6 contain a complete, beautifully written solutions guide showing every single step of the calculation (re-writing signs, collecting terms, and isolating operators) for all 48 questions. This makes marking incredibly fast or allows for flawless pupil self-checking!

Educational Standards & Curriculum Alignment:
UK National Curriculum (Key Stage 3 & 4 Mathematics):

• Number: Order positive and negative integers; use the four operations, including formal written methods, applied to integers.
• Understand and use the rules for multiplying and dividing signed numbers.
• Use conventional notation for the priority of operations, including brackets, powers, roots, and reciprocals (BIDMAS).
