NUMBAT OER - Open Educational Resources

1. Introduction

This helpsheet is concerned with the ways that we express quantities that are not whole numbers, and how we express numbers in relation to other numbers. You may also need to refer to helpsheets on powers, measurements, and concentrations and dilutions.

All of the topics that are covered here will be familiar from everyday life, but you may have already found problems with the calculations or with converting from one form to another.
