Understanding math via the real world.
This one's a bit more complicated, but still just using the right formula. The compound interest formula is:
A=P*(1+ r/n)^(nt)
A= amount you will have (not just the interest)
P = principal (deposit)
r = interest rate (as a decimal)
n = number of times per year the interest is compounded (daily = 365)
t = time in years
Plug everything in, just be careful about how you do the calculation (be sure to follow the order of operations).
