Some of the kinds of numbers are: complex numbers, imaginary number, real numbers, transcendental numbers, algebraic numbers, rational numbers, irrational numbers, integers, positive integers, negative integers, .zero, and counting numbers.

Computers have limits on the largest and smallest numbers that can be represented and rounding or approximation of numbers.

**Elementary algebra** is the mathematical field of study of the properties of operations on the real number system and complex number system and the relations between real and complex numbers which involve a finite number of additions and muliplications. These can be extended to solutions of equations that may require an infinite number of additions and multiplications.

# free music player coding example

**Coding example:** I am making heavily documented and explained open source code for a method to play music for free — almost any song, no subscription fees, no download costs, no advertisements, all completely legal. This is done by building a front-end to YouTube (which checks the copyright permissions for you).

**View music player in action:** www.musicinpublic.com/.

**Create your own copy** from the original source code/ (presented for learning programming).

Because I no longer have the computer and software to make PDFs, the book is available as an HTML file, which you can convert into a PDF.
