http://www.wolframalpha.com/ The Wolfram Alpha project is a web site front-end (i.e. user-interface) for an artificial intelligence program that is learning how we humans solve complicated mathematical problems. For the record, AI programs that performed simple logical reasoning and solved simple algebra equations existed in the 1980s. Wolfram.com has offered the excellent "Mathematica" program for personal computers since the late 1980s. Mathematica helps college students and faculty solve some complex math problems very quickly and accurately, making their personal computers in effect "super calculators" that do much more than the math basics such as: add, subtract, multiply, and divide, calculate the square a number (i.e. multiply a number by itself), find the square root of a number, etc.
