I am a first year university student and found that entering notes in the computer is much better than maintaining notes in the note book. But i have problem entering math questions/figures in my computer like square roots, subscripts etc. It just takes too much time and effort. I use an app called Evernote. It would be great if anyone can suggest me a solution.
It can only be done if you are using a word processor that would aceept math symbols (like Yahoo answers).
Just cut and paste.
There are other sites like this should you wish to browse and choose another. Go to any search engine and type "HTML math symbols".
