I Like the Idea of Learning in Public

[aesmael]

(also funny looking capitalisation) and consequently intend to post entries about whatever I am studying at the time. One subject I wish to spend more time learning is mathematics so I would like to ask if anyone reading knows of a program I could use to 'do' math on a Windows computer? Preferably one which is also friendly toward livejournal posts. Either way, 'tis off on a slow, half-hearted search for my goal. Self, away!
