One of the two dollar amounts must be entered as a negative number and the other as a positive number or an error will result. On the BAII Plus, press 6 divide 12
= I/Y, 0 PV, 450 PMT, 200000 +/- FV, CPT N. On the HP12C, press 6 ENTER 12 divide i, 0 PV, 450 PMT, 200000 CHS FV, n. Note that the HP12C returns a result of 235. Make sure the BAII Plus has the P/Y value set to 1.
