In a Python shell, add 2 and 2 as follows:

>>> 2 + 2
4

Multiply 2 and 2 as follows:

>>> 2 * 2
4

Divide 2 and 2 as follows:

>>> 2/2
1

If you have programmed before, you probably know that dividing is a bit tricky since there are different types of dividing. For a calculator, the result is usually adequate, but the following division may not be what you were expecting:

>>> 3/2
1

We will discuss what this result is about in several later chapters of this book. Take the cube of 2 as follows:

>>> 2 ** 3
8
