Intervals

What do I want from you today?

In this chapter I will teach you to work with intervals, note them down properly and graph them on a real number line. You will learn what types of intervals exist and what the difference is between them. In the end, I will show you how to make an intersection and a union of two intervals because this skill is really very important so don't underestimate this topic.

When are you ever going to use this knowledge?

You can find the answer to this question at the end of this chapter, where I will tell you, in which particular cases in life you will meet with intervals... patience brings roses.

How will it relate to mathematics?

Intervals are used really almost everywhere and so it's important to be educated about them. You will encounter them, for example, in determining conditions for variables in equations and inequations, or in solving a system of linear inequations.
