Re: Present Value

Hi MIF;

Looks good. Thanks for the page.


In mathematics, you don't understand things. You just get used to them.
Of course that result can be rigorously obtained, but who cares?
Combinatorics is Algebra and Algebra is Combinatorics.

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.

Interesting paper. Good use of the guess and try idea.
