Sets
Forget everything you know about numbers. In fact, forget you even know what a number is. This is where real mathematics starts. Instead of math with numbers (which is mostly Arithmatic), we will now think about math with "things".
But it's better to start with some basic knowledge of numbers, their classification and their applications. Don't take the trouble of searching for the topics in google , I will help you!
Well now, you are done with the basics and can get into the topic of Set Theory.
Hang on ! Are you asking WHY should I learn this topic? Here you can find ample examples of where Sets are used.

A Venn diagram or set diagram is a diagram that shows all possible logical relations between a finite collection of sets. Venn diagrams were conceived around 1880 by John Venn. They are used to teach elementary sets, as well as illustrate simple set relationships in probability, logic, statistics,linguistics and computer science.
