Mathematics Specification A - 4MA1 PearsonEdexcel

Integers

Gbogbo ọrọ náà

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.

Ebumnobi

Akọmọ Ojú-ẹkọ

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.
