Need a Calculator in AS3 please...

I agree with joshstrike...that code is chaos. You might also think of using a dictionary to index your buttons against their value

var codeByButton:Dictionary = new Dictionary();
codeByButton[bt0] = 0;
codeByButton[bt1] = 1;
...

I mean if you had to have the buttons onscreen before and you couldn't generate them with code --

var currentStr:String = "";
var tot:Number = 0;
var buttons:Array = new Array();
for (var i:Number=0;i<10;i++) {
   buttons.push(root["bt"+i]);
   buttons[buttons.length-1].name = String(i);
}
var operators:Array = ["+","-","/","*"];
for each (var o:String in operators) {
   buttons.push(root["bt"+o]);
   buttons[buttons.length-1].name = o;
}
for each (var b:MovieClip in buttons) {
   b.addEventListener(MouseEvent.CLICK,this.gotPress,false,0,true);
}
function gotPress(evt:MouseEvent):void {
   //something like this; numeric inputs are added to the string
   if (!isNaN(Number(evt.target.name))) {
      //literally tacked on at the end of the string as a substring.
      currentStr += evt.target.name;
   } else {
      //if no total exists, 
      !tot ? tot = Number(currentStr) : void;
      //eval() is gone =\
      switch (evt.target.name) {
          case "+": 
          currentStr = String(Number(currentStr)+tot);
          break;
          case "-":
          currentStr = String(tot-Number(currentStr));
          //etc.
       }
    }
}
}

I just realized that won't work 'cause the operations are retroactive...uh...you'd just have to queue the last operation.
Whatever.
Point is use a loop to add your buttons and events

How would you reuse the answer once you did a calculation? EX: 4+3=7 + 3=10
I understand you need an array, but how do you implement it?
