I have just finished making a Percentage Calculator that includes info on how the answers were arrived at. Please check it out (and in, up and down) to see if I have somehow made a mistake. I wouldn't want to mislead lots of people with a faulty calculator.

And if you have any ideas for the "Here are some ideas" section at the bottom of the page, let me know.

Thanks!

Excellent!

The Percentage calculator has been designed very well.

All the additional information given is helpful.

I tried the calculator for some known values, and found it working well.

Beginners using this calculator would learn a lot.

Very well done, MatsIsFun!

I have to say this again: like always, it's fabulous.

The only problem I have found so far is that when you click the 'MathsIsFun.com' button in the flash window, it links to the Symmetry Artist (?).

And the same button in the Symmetry Artist window links back to itself.
