There are 6 lessons in this math tutorial covering Identities. The tutorial starts with an introduction to Identities and is then followed with a list of the separate lessons, the tutorial is designed to be read in order but you can skip to a specific lesson or return to recover a specific math lesson as required to build your math knowledge of Identities. you can access all the lessons from this tutorial below.

In this Math tutorial, you will learn:

• What is an identity in math?
• Where does a conditional identity differ from an identity?
• What is another name used for conditional identities?
• What are inconsistent equations?
• How to make the distinction between identities, conditional identities and inconsistent equations?
• How to solve a question in math by proof?
• How to disprove a claim in by counter - example in math?

## Introduction

In tutorial 6.3 we discussed the eight special algebraic identities. Are they true for any number you choose to insert to replace variables or are they true only for some numbers?

How many values can you insert in the place of x in the equations 0x = 0 and 1x = x? What about the equation 0x = 6? How many possible roots do they have?

All these questions (and many others) are explained in this tutorial, which focuses on identities, as special equations.
