There are many types of numbers in the world.
Actually, the numbers are.... just numbers in nature. But sometimes we human beings really
like deviding and naming. For example, Exact 5 inches do not exist in nature. Even though we make a ruler and
estimate 5 inch, it is not a exact number.(It may be close to 5 inches)

But numbers are divided into several section according to the characteristics, and you have to be familiar with
these numbers because you use those.(You will use imaginary numbers even though these number do not exist)
So, let me introduce many types of numbers for you.

First, natural numbers. These are 1, 2, 3, 4,,,,,,,,, 1000,, 142342352352,,,.
You may not call there are 4.3 tigers in the cage, but call there are 4 tigers.
These are natural numbers!
