We just used the *integer* number **class** but there are many more.

* Integer/Fixnum (whole numbers)
* Integer (whole numbers)
* Float (numbers containing decimals)
* String (words, sentences, literal text) - requires quotes

Heads up! Older versions of Ruby call it `Fixnum` instead of
`Integer`. For the purposes of this workshop, whenever you see
