In mathematics, you don't understand things. You just get used to them.
If it ain't broke, fix it until it is.
Always satisfy the Prime Directive of getting the right answer above all else.

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.
