Numeric data types are crucial in Python, so it is important to start with them. Here you will work with simple math operations and find out the purposes of learning different types of numerical data.

The main goal of this section is to clarify the boolean data types; it's a sub type of numeric data, but indeed it is more challenging. Since it is always better to excel in the more difficult topics, this section is a valuable part of your curriculum.

Strings are a way for us to implement your phrases in Python, that is, to give instructions to users who are the target audience of your program. Indeed, it is always better to be able to work with strings because they should be used in your code. You'll understand why soon.

This chapter consists of practical tasks that combine all the examined topics together with a bit of theory.

Sign	What Does It Do	Example	Result	Application features
`+`	Adds numbers	`5 + 4`	9	-
`-`	Subtracts the right-hand number from the left-hand one	`5 - 4`	1	-
`*`	Multiplies numbers	`5 * 4`	20	-
`/`	Divides the left-hand number by the right-hand one	`20 / 4`	5	Do not divide by zero
`**`	Elevates the number on the left to the power of the number on the right.	`2 ** 3`	8	-
