; This example file shows how to solve compound interest problems.
;
; The compound interest formula is
;
;      future_value = present_value * (1 + interest_rate) ^ n
;
; First create a user-defined function for future value

fv(pv,i,n) = pv * (1 + i) ^ n

; Now you can use this function to compute future values with
; different parameter values.

; If $1000.00 is invested at 7% interest compounded annually, what
; will be the value at the end of eight years?

future_value = fv(1000.00, 0.07, 8)

; The answer is displayed and also stored in the variable future_value
; for later use in other expressions.
