Martindale's Calculators On-Line Center




Created by Jim Martindale, this website has over 23, 785 different calculator applications. Each application is specific to a course or concept. The site contains every possible course, high school and college with applications specific to material from that course (pre algebra, algebra I and II, precalculus, geometry, calculus, etc.).

What is most interesting to me, although not necessarily useful, are some of the more unique calculator applications. For example, one is Egyptian Number Conversion, in which an Egyptian number calculator can configure Egyptian standard to English, or vice versa. There are also different measuring systems created by Egyptians, and provides historical means of mathematics used by Egyptians (ex. Triangular Calculations, used for Pyramid construction).

I recommend this site to any mathematics teacher, especially secondary education, who wants to incorporate specific calculator functions into their lessons.
