NUMBERS

Hi People!
Today i want to speak about the numbers. Every year in class, at the beginning of the course we have always spoken about natural numbers, integers, rational, etc... How many numbers did we know until now? Well we were debate how many there are. Our teacher said that we had to do a search. And finally with all my classemades found SEVEN different tipes of numbers:

-Naturals (1,2,3,4,5... Not negative and not decimal...)

-Integer (Positives, negative and 0)

-Racionals (Proporcional numbers)

-Decimal (Comas)

-Irracionals (We can't expresse that in fractions)

-Reals

-Complex (imaginaries___ i2=-i)

He tell us that numbers are like a russian dols. First we have N(Natural numbers), N numbers are the most simple. Then we have Z(Integer numbers), those numbers have natural numbers inside. The same with the Q(Racional numbers), N and Z are inside of Q. And R(Real numbers) have inside N, Z and Q. Finally we have C(Complex numbers) C are numbers to resolve things imposible.

There ia a diagram of that numbers:
