In this section you will find useful documentation relating to mathematics that I have developed over the years. The calculators I've developed for fun and profit, the rest I did while I was teaching Mathematics at Pima Community College in Tucson, AZ.

The "Systems" and "Simplex Method" pages use JavaScript for all calculations. If you view the source, you'll notice I have a rather odd method for doing the calculations. I use what I call "Rational Calculating." I store the each number in a two-dimensional array - one for the numerator and one for the denominator. The four basic operations - addition, subtraction, multiplication and division - are very easy to do this way, and I keep very accurate values during intermediate operations because there is no round-off error.
