Wolfram Alpha ♥ ♥ ♥ ♥

First thing I could say about this website is awesome! It acts like a calculator, I entered in a simple problem solving with variables. I typed in 60=5N, and it showed me the answer for the problem. Also, I could upload files in this website and then I could create a URL for the file, so if I was to lose a file and if I made a URL for the file on Wolfram Alpha, I could easily copy the URL and paste it in the web address bar, I just recovered my lost file. If I was teaching math class, I would have my students use this website to solve math problems. Out of all the Ed techs I have reviewed so far, I say this is the best one out of all four.
