This is a compounding equation, and the annuity equations are sort of "built on" this one, so you're not only not dividing by interest but there's no extra 1 - or - 1 in the numerator either. I'm rather shocked over the idea that your book would do annuities but never have done just plain compounding first, as that's the normal progression of things. Compounding is where you just have a lump sum and all you do is earn interest, but you don't add or take away any payments along the way. So you plop $1000 in the bank and let it sitting compounding interest on, but you never add another$1000 to it yourself, whereas an annuity you would be adding another \$1000 each year/month/whatever.

The initial equation Mark gave is the compounding equation and I'd highly suggest learning that one as well. You can then solve for anything in it. (Keeping in mind that n = time x compounding periods per year, in case you have to solve for the time.) For things like doubling, just use a 1 and a 2 -- that tends to throw people off cause it's too simple.
