You might be surprised to hear that study of whole numbers (or **integers**) carries right on through university level and beyond. There is a whole area of mathematics, called **number theory** that looks exclusively at whole numbers and the patterns in them (such as **prime numbers**).

At this level we will consider four main topics within our study of whole numbers:

2.) Multiplication & Division;

3.) Squares, cubes, roots & indices;

4.) Multiples & factors.
