```
function myClass() { 
    this.nums = [1,2,3]; 
    this.divisor = 2; 
}

myClass.prototype.divideNumsByDivisor = function(){
    return this.nums.map(function(num) {
        return num*this.divisor; 
    });
}

```

`myClass.divideNumsByDivisor()` was suposed to multiply each number on it's member variable `nums` to the value on it's member variable `divisor`. 

This is not working because the function `function(num) { return num*this.divisor; }` is pointing this to a wrong object.
