Calculator.equals() not totaling up and returns "NaN" in console

What's wrong in my code?

var calculator = {
        sum: 0,
        add: function(value) {
       this.sum += value;
    },
    clear: function() {
      this.sum = 0;
    }, 
    equals: function() {
      return this.sum;
    }
}

Hi Jeannie,

by using the markdown cheatsheet it is a lot easier to read your code. Please have a look at it.

Are you completing the challenge? Because from what I can tell your code is not the same as in the final challenge.

I just tried it. Once you use your code and add the missing functions to it, it should work.
