Code: Select all

function MyMath(){
   this.StartMath = function(a,b,c){
      this.a = a;
      this.b = b;
      this.c = c;
      this.DoMath();   
   };
   this.DoMath() = function(){
      this.total = this.a +this. b - this.c;
      return this.total;
   };
   
}
function MathResult(){
   this.ShowMathResult = function(){
       alert(this.total);
   }
}
