I was taught math. I even got a college degree in math (albeit abstract math). I learned summations and limits and all sorts of things. Never once were any of these abstract calculations referred to as "simple interest" or "compounding." The terms could have easily been integrated into ordinary math classes without decreasing the actual math being taught - and while I can't speak for all students, it certainly would have helped me.

Really Liz?

I thought the interest compounding continuously was one of the classic examples of e.

IE A being the balance after t years, and P being the initial deposit, and r = annual interest rate.

If interest is compounded n times a year the equation for compound interest is

A = P*(1+r/n)^nt

When n -> infinity
Then A = Pe^rt

Not that it made much impact on me at the time.

Then again, I had to learn all that crap later. Sure I use it, but a good way to make someones eyes glaze over is to start talking about interest rate vs discount rate and all that. I can make someone fall asleep at thirty feet

Ok, I admit it. I can be a pedantic bore at times
