Generating subtraction equations that only return positive values

Question

Hello!
Can you please help me to create a random subtraction equation where the result will always be positive? For example, my current scripting will return something lilke 3-6=-3. I don't want equations like this- only postive answers.
Thanks for your help!
//random numbers
//1.
function randomNumbers(min:Number,max:Number) {
   var Results:Number=Math.floor(Math.random()*max)+min;
   return Results;
//2.
new_mc.addEventListener(MouseEvent.CLICK, showRandomnumber);
//3.
function showRandomnumber(event:MouseEvent):void{
   r1_txt.text = String(randomNumbers(1,10));
   r2_txt.text = String(randomNumbers(1,10));
   a1_txt.text = String(Number(r1_txt.text) - Number(r2_txt.text));

Answer 1

I see.
How about you try to pass the first generated value the second time you call the function? Like so:
// Your function definition.
function randomNumbers(min:Number,max:Number) {
   var Results:Number=Math.floor(Math.random()*max)+min;
   return Results;
// Connecting the event handler.
new_mc.addEventListener(MouseEvent.CLICK, showRandomnumber);
// Check the r2 line.
function showRandomnumber(event:MouseEvent):void{
   r1_txt.text = String(randomNumbers(1,10));
   r2_txt.text = String(randomNumbers(1,r1_txt.text as Number));
   a1_txt.text = String(Number(r1_txt.text) - Number(r2_txt.text));
Ofcourse, this leaves you with the possibility that r2 is the same as r1, leaving 0 after subtraction. But it shouldn't give you any negative numbers.
