Resources in this category:

Calculating Machines
http://192.220.96.166/

"Site deals mainly with the mechanical calculating machines from a collector's point of view" Provides historical information, interactive computing programs and related links to references on calculating machines.

Calculator.Com
http://www.calculator.com/

Directory of online calculators, browsable by a hierarchical subject/function directory. There are calculators for finance, business, science, calculus, arithmetic, geometry, etc.. Also, includes calculators for cooking, hobbies, and health. "Some solve problems, some satisfy curiosity, and some just for fun."

A Dictionary of Units
http://www.cleavebooks.co.uk/dictunit/dictunit1.htm

"Provides a summary of most of the units of measurement to be found in use around the world today (and a few of historical interest), together with the appropriate conversion factors needed to change them into a 'standard' unit of the S.I. ('Systeme International')." Search by category (length, mass, density, energy etc.), or alphabetically.

Math2.org (Formerly Dave's Math Tables)
http://www.math2.org/

Contains numerous links to mathematical tables for various subjects: general math, algebra, geometry, trigonometry, calculus, and advanced topics such as fourier series and transforms. It provides formulas, diagrams and proofs which are all very useful in mathematics.

Mathematical Functions
http://functions.wolfram.com/

"Provides the mathematical and scientific communities with the world's single most comprehensive resource about mathematical functions. Its vast collection of formulas, currently totaling in excess of 37,000, was assembled and verified using the powerful features of Wolfram Research's technical computing system Mathematica."

Mathematical Programming Glossary
http://glossary.computing.society.informs.org/

A glossary of terms used in mathematical programming and related subjects such as mathematics, economics and computer science. Includes supplements to elaborate on important concepts and links to additional mathematical dictionaries and encyclopedias.

Measure 4 Measure
http://www.wolinskyweb.net/measure.htm

"A collection of interactive sites on the web that estimate, calculate, evaluate, translate, etc. In other words, they do the work for you." These sites allow you to convert between different units of measurements, find your ideal caloric consumption, calculate the amount of paint you need to paint a room, and much more.

Webmath.com
http://www.webmath.com/

Webmath not only solves your math problems, it shows the steps taken to reach the solution. Types of problems inlude everyday math (i.e. figuring out a tip), polynomials, units conversions, and quadratic equations.
