compund interest :
Principal = $680 Rate = 6.2% Time = 10 years
680*(1 + 6.2%)^10
the formula is A=P(1+r)^t
A=680(1+0.62)^10
A=(680+421.6)^10
A=1101.6^10
A=2.63171752 × 10^30
then just do scientific notation on the last step to find the total account w/ total interest
680 x 1.062^10
=1240.949419
Pert
Principal times e (button on you calc) times Rate times the Time
