Financial Problem
Is there a way to distinguish between which formula to use for a financial problem that asks you to find the regular payment? The future value of an annuity or present value formula?

e^(i*pi)
Compound interest formula is usually the best place to start

$A_t = A_0\left(1+\frac{x}{n}\right)^{nt}$

Where:

• A_t = Amount at time t
• A_0 = Inital amount
• x = annual interest rate
• n = compound period
• t = time

Noooooo...when calculating loan payments, use the "payments formula";
use the present value formula when calculating present values!
