1. Because the compounding periods and the withdrawal periods are
not coincident, you must first convert the nominal interest rate to one in
terms of the withdrawal periods. You can do this using the ICNV
menu, as explained on page 87, "Compounding Periods Different
from Payment Periods."
2. The rest of the calculation is a straightforward TVM problem.
Remember that money deposited is paid out and therefore negative;
money withdrawn is received and therefore positive.
