What includes natural numbers and zero?

Answer 1

Whole Numbers are only natural and zero

Integers are positive, negative numbers and zero

Rational Numbers include all Integers, along with any terminating, or repeating decimal numbers. (All fractions are rational numbers)

Irrational Numbers include all non-repeating, continuous decimal numbers (Pi is a good example of an irrational number)

Real Numbers include all of the above

Imaginary Numbers include any number that is not real. (iis the only example of an Imaginary Number that I know of)

I know I went into MUCH more detail than asked for, but I figured why not.
