CRAM Math Properties of Real Numbers

For the first two semesters (Algebra I/II), nearly all work is done in the real number system. The follwoing properties of real numbers provide us with a definition of real numbers in the context of algebra and CRAM Math.


 * There are other number systems in algebra, such as the natural numbers and the rational numbers, but for now, we will concentrate on learning the real numbers as the most general system usually taught in Algebra I/II.

Two basic operations on real numbers
To start, we will allow that you can add and multiply real numbers together according to the following properties.
