This unit explores reasons for studying mathematics, practical applications of mathematical ideas and aims to help you to recognise mathematics when you come across it. It introduces the you to the graphics calculator, and takes you through a series of exercises from the Calculator Book, Tapping into Mathematics With the TI-83 Graphics Calculator. The unit ends by asking you to reflect on the process of studying mathematics. In order to complete this unit you will need to have obtained a Texas Instruments TI-83 calculator and the book Tapping into Mathematics With the TI-83 Graphics Calculator (ISBN 0201175479).

After studying this unit, you should:

- be able to describe your view of what mathematics is;
- have begun to recognise different types of written mathematics and developed your skill at reading it;
- be able to tackle mathematical problems using a calculator and with understanding for basic arithmetic, percentages, square roots, reciprocals and powers;
- be able to express and interpret numbers in scientific notation, both in writing and on your calculator;
- be able to give some examples of common mathematical ‘doing–undoing’ pairs of operations;
- be more attuned to noticing mathematical questions arising from the world around you.

# Maths everywhere

## Introduction

This unit explores reasons for studying mathematics, practical applications of mathematical ideas and aims to help you to recognize mathematics when you come across it. It introduces the you to the graphics calculator, and takes you through a series of exercises from the *Calculator Book*, *Tapping into Mathematics With the TI-83 Graphics Calculator*. The unit ends by asking you to reflect on the process of studying mathematics.

**In order to complete this unit you will need to have obtained a Texas Instruments TI-83 calculator and the book Tapping into Mathematics With the TI-83 Graphics Calculator by Barrie Galpin and Alan Graham (eds), Addison Wesley, 1997 (ISBN 0201175479)**.
