我在看到note 1: 89页的时候有个问题实在搞不懂.89页最上面,(也就是88页最下面)的那道Example: PV of an ordinary annuity. 它给出的答案是input: N=13; I/Y=6MT=-200;CPT->V=$1,770.54,可是我怎么也得不出这个结果.输入得到的结果是一个3.31668的奇怪数字.请各位指教.

ok got it! Here i would also like to inform other candidators that be award of the caculator's memory problem. CLEAR YOUR CACULATOR'S MEMORY, especially for the TVM work! press the 2ND and CLR TVM each time before TVM caculation. It will be an insurance note!
