Integers
Overview
Integers are the building blocks of mathematics. Every calculation you meet in your Edexcel exam, from simple arithmetic to advanced algebra, rests on a confident handling of whole numbers, their properties, and the rules that govern operations on them.
In this topic you will master the four operations with positive and negative numbers, apply the correct order of operations (BIDMAS), and learn to identify prime numbers, factors and multiples. These skills underpin every other area of the specification.
Objectives
- Understand and use integers (positive, negative and zero)
- Understand place value
- Use directed numbers in practical situations
- Order integers
- Use the four rules of addition, subtraction, multiplication and division
- Use brackets and the hierarchy of operations
- Use the terms 'odd', 'even', 'prime numbers', 'factors' and 'multiples'
- Identify prime factors, common factors and common multiples
