WolfgramAlpha is a search engine that allows users to search for fact based information on a variety of topics. Its kind of like if Google searched the encyclopedia. The really cool thing about using this tool is that you can type in mathematical equations and expressions into it and it will give you a written and graphical solution, as well as a step by step solution to see how it was done. This is a great tool for students or parents to be able to check their work. Test it out, and you will easily see its value.
