Intro to Number Sets

There are several common sets of numbers that mathematicians use in their studies. In order from simple to complex, they are:

1. The natural numbers $N$

2. The integers $Z$

3. The rational numbers $Q$

4. The real numbers $R$

5. The complex numbers $C$

Each set is constructed in some way from the previous one, and this path will show you how they are constructed from the most basic numbers. You may have come across these terms in a math class that you attended, and may have had other definitions given to you. In this path, you will obtain a firm, complete understanding of these sets, how they are constructed, and what they mean in mathematics.
