Positive and Negative Numbers

Learn about positive and negative numbers, identify practical situations in which negative numbers are used, measure temperatures above and below zero and compare positive and negative numbers. This course is ideal for intermediate learners.

Introduction 

A negative number is less than zero. When we write negative numbers we put a negative sign before the digit. Sometimes negative numbers are called minus numbers – be careful not to confuse these with subtraction. For example: -5, -14 and -27 (these numbers all have a negative sign before the digits).

A positive number is more than zero. Unlike negative numbers, you do not need to put a sign in front of positive numbers. For example, 5, 29, 114 (these do not have a negative sign).
