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

Number line

- The number line is a conceptual visualization of how numbers are physically related to one another.

- A number line ideally represents an unassigned dimension.

- Number lines represent dimensions of ideas that can be measured or counted.  The ideal number line represents the dimension of numbers.

I've just listened to the millidiem. Cool. Reminds me of Purcell (English Renaissance), Handel (German/English Baroque), and Terry Riley (American contemporary). It invites musical elaboration and invention.”
