While I was coding around with flash, I quickly thought up of a calculator you repeatedly have to program.
Here is the code:

//CALCULATOR CODE//
var x:Number = new Number(5546);
var y:Number = new Number(1);
var Solve1 = x-y;
trace(x + " - " + y + " = " + Solve1);
//END CALCULATOR CODE//

Line 1.
- variable x is defined with the number 5546.
Line 2.
- variable y is defined with the number 1.
Line 3.
- Solve1 is a variable with equals x-y. So it's taking the values 5546, and 1, then subtracting them. You can also do something like; x * y + r / t
Line 4.
- Traces whats between the parenthesis to show in the output box.
Now CTRL+ENTER, now the output box should read "5546 - 1 = 5545"

I know my way around with flash. I have been programming for almost 2 years.
