I'm trying to solve a math problem that asks to to find the interest when it has been compounded continuously, although, the formula it gives me to solve it is not clear. It tells me to take the principle which is $60000 and multiply it by (italicized e) to the power of rate times interest which is 9 years at a 5% interest rate. Can someone explain what the italicized E is so that I can figure out this problem?
 
The correct formula is A = P * (1 + (r/n))^nt. There is no italicized e.
A = amount of money accumulated after n years, including interest.
P = principal amount (the initial amount you borrow or deposit)
r = annual rate of interest (as a decimal)
n = number of times the interest is compounded per year
t = number of years the amount is deposited or borrowed for

Since you're only looking for the interest deduct the initial investment from the total accumulated amount. (A - P)
