Like Khan Academy, WolframAlpha is a website everyone should know about– especially anyone taking a math class or helping someone else enrolled in a math class. This evening, I used WolframAlpha to check several different problems my son was working for an end-of-year assignment in his Geometry class. You can see the syntax I used in the screenshots below. Wolfram Alpha supports solutions for complex problems using straightforward language. This kind of computation isn’t possible with a ‘normal’ calculator. As with a calculator, a powerful tool like WolframAlpha doesn’t replace the need to understand mathematical concepts and processes, but it certainly CAN make it easier to use those algorithms to solve problems.
Some of the problems (like the initial examples of temperature conversions) could also be done with a simple query to Google, but the more advanced problems definitely could NOT. GoogleGuide.com has a nice collection of techniques for using Google as a basic as well as advanced calculator. Google can’t do everything WolframAlpha can do, however!
