    The compound interest formula, A = P(1 + r/n)^nt, is explained with all variables defined. Then, the interest formula where interest is compounded continuously, A = Pe^rt, is explained. Both formulas are then used to solve compound interest problems. All steps and work involved is explained and shown. This is a must-watch for anyone learning about compound interest.
