Rather than preparing students for Calculus, today's reality is that College Algebra is, currently, the terminal mathematics course for most students. and in other disciplines .... then College Algebra could not only help reverse today's unacceptably high rate of college failure but it could ... give students a more positive attitude toward mathematics and a greater ability to use mathematics in their personal and professional lives.

Algebra is a branch of mathematics sibling to geometry, analysis (calculus), number theory, combinatorics, etc. Although algebra has its roots in numerical domains such as the reals and the complex numbers, in its full generality it differs from its siblings in serving no specific mathematical domain. Whereas geometry treats spatial entities, analysis continuous variation, number theory integer arithmetic, and combinatorics discrete structures, algebra is equally applicable to all these and other mathematical domains.

Algebra relies on an established sequence for performing arithmetic operations. This ensures that everyone who executes a string of operations arrives at the same answer. Multiplication is performed first, then division, followed by addition, then subtraction. For example:

The whole book Linear Algebra along with the answers to all exercises. If you save these two files in the same directory then clicking on an exercise will send you to its answer and clicking on an answer will send you to its exercise. This does not work on the web, it only works if you download the files.
