The Number Systems
One, two, three, and on forever are Natural Numbers
Add a zero to get Whole Numbers
Add a positive or negative sign to get Integers
Put a number up over down to get Rational Numbers
Most radicals, pi, and the like are Irrational Numbers
These are all Real Numbers, except the Imaginary Number, i
