what?

I don't understand what this is for.

rnfp!!!!!!! it so confusing.

It is the definition of terms in a financial equation like     FV = PV (1+r/100)^n   

        If you have a present value (initial deposit) of $50   and and  annual interest (r) of 6 percent compounded annually for 7 years(n), it would look like this:

FV = 50 (1+6/100)^7

FV =$ 75.18       Would be your Future value after 7 years

There are SCADS of other financial equations that use these terms in various ways.....

ok thank you

no, it good this is the one I what.

so I do FV = 50 (1+6/100)^7 then what 

steps for the rate.
