Mathematics Specification A - 4MA1 PearsonEdexcel

Integers

Bayani Gaba-gaba

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.

Manufura

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

Takardar Darasi

Temperature below zero, bank overdrafts, floors below ground level: negative numbers appear everywhere in daily life. The full set of integers stretches from negative infinity through zero to positive infinity, and being able to calculate with all of them is the first skill this specification demands.
