Maths of finance

One would call this an experimental post. Right now I am typing this out on my Blackberry while in math class.
We just spent around 48 minutes debating how to solve an annuity problem. I still don’t think my professor ever wrote the right anwser on the board.
Now that I have mentally checked out of the lecture she moves on to the next problem.
Just a mini-post. Turkey details later.
