JavaScript Object-Oriented JavaScript (2015) Introduction to Methods Finishing the Calculator

When I'm doing task 3 and setting this.sum /= value; I get an error stating that task 1 one is no longer correct.

I think it may be a bug

calculator.js 
var calculator = {
  sum: 0,
  add: function(value) {
    this.sum += value;
  },
  subtract: function(value) {
    this.sum -= value;
  },
  multiply: function(value) {
    this.sum *= value;
  },
  divide: function(value) {
    this.sum /= value;
  },
  clear: function() {
    this.sum = 0;
  }, 
  equals: function() {
    return this.sum;
  }
}

Hey Ashton,

You are doing good but you don't need the equal (=) symbol in the multiplication or the division!

divide: function(value) { this.sum /= value; },

does work, or

divide: function(value) { this.sum /this.sum = value; },
