Re: Present Value

Hi MIF;

Looks good. Thanks for the page.


In mathematics, you don't understand things. You just get used to them.

I agree with you regarding the satisfaction and importance of actually computing some numbers. I can't tell you how often I see time and money wasted because someone didn't bother to run the numbers.

Re: Present Value

Well then, here is another (somewhat duplicated beginning): Net Present Value NPV

Re: Present Value

Hi;

For someone whose business acumen consists of only knowing when they overcharged me it is quite intimidating. But I think I got it!

Re: Present Value

Hi MathsIsFun

Been away, so only just seen this.  Looks good and it is clear.

Just one suggestion.

About 3/4 down, where you are using a calculator, you say

1.10 to power 6 is better than 1.10 x 1.10 x 1.10 x 1.10 x 1.10 x 1.10

Could you say is quicker to calculate ?

Quicker is better, so better will become quicker.
