Put a negitive sign on the calculator.
It would be nice to use negatives to do more complicated problems than having an error come up.....

Currency does not work
The currency converter keeps reverting to the last country in the list  very infuriating. I put in Euros and then Sterling but when I put the number into say Euros it changes the Serling to Zambian currency

Filter out unwanted characters.
First, great calculator! Thanks for the tool!  Second, if you enter/paste in a value that has illegal characters in it, the calculator breaks. Example: "139,359.99" breaks because of the comma. If you do a find and replace or a regex replace and remove the unusable characters on change, this shouldn't happen. Thanks!
