math object

I am building a simple calculator and for some reason I can’t figure out I’m getting an extra “0” I have an input text box named “input” with an instance name of “input” I have a dynamic text box named answer with an instance name of “answer” I have a variable with the name of “hold” and I have a button with the code

on(release, keyPress "<Enter>") {
hold = Number(input * .0625);
answer = Number((input + hold) * .1);
}

When I test this by entering the number “10” into the input box and clicking the button it gives me the answer “10.0625”

BTW that * .1 on line three is because without it I get the answer 100.0625

Any ideas what’s going on?
