Why is this function not working?

All functions worked but the Divide one, why?

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.divide /= value;
  },
  clear: function() {
    this.sum = 0;
  }, 
  equals: function() {
    return this.sum;
  }
}

divide: function(value) {
    this.divide /= value; // <- change this.divide to this.sum

My comment to the right side says to change this.divide to this.sum. That will fix your error.
