Answer 1

Good job, but you can improve it by many ways: handle case of cancel button of alert()/prompt() by user, or better, rewrite your code to avoid use of alert()/prompt()/confirm() functions ( not user friendly ;) )...

You can do that by writing an Html/css alternative to the 'alert' kind buit-in boxes, or integrate the necessarly form elements to get input from user more statically in your page design/template ( and why not doing some numeric/operators keyboard and display to make a realistic virtual calculator ;) )

Answer 2

I've just had a look, it's really good! :)

Answer 3

Thank you very much

Answer 4

It is really good, but it's not user friendly. And i think you should make an alert if what you put is a string or char instead of number. :-)
