An Integrator at GraphPower
We’ve just started a new website, GraphPower.com. Our goal is to use that website to provide great calculus software. First up is an online integrator for definite integrals. Just by itself, it should be a great help for calculus students who want to check their work, but we’ll be rolling out a whole bunch of other integrators really soon.

Cryptarithmania Is Live!
In time for Christmas, the Cryptarithmania site is now live and online! You can sign up to receive cryptarithm puzzles in your email Inbox, or buy a CD of over 4 million cryptarithm puzzles. In case you don’t know what a “cryptarithm” is, it’s a puzzle where an arithmetic sum has been changed, replacing each digit with a different letter. Your goal is to figure out what each letter represents. These puzzles are often called alphametics, or crypt-arithmetics or letter or verbal arithmetic. The classic example is SEND + MORE = MONEY, where M represents 1, and… hey, but why should I spoil the puzzle for you! Hop over to www.cryptarithmania.com now and grab yourself some puzzles.
