# Now, implement the multiply method.

there is alreadyh a multiply method on here

calculator.js
```var calculator = {
sum: 0,
this.sum += value;
},
subtract: function(value) {
this.sum -= value;
},
multiply: function(value) {

},
divide: function(value) {

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

Yes. You now have to implement it. You have to write the body of the method just like you did for the subtract method.

```var calculator = {
sum: 0,
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;
}
}
```

Hi there! Yes, there is. They simply want you to add the code that makes the method do something, which is what they mean by implement. The code will be very similar to what is already there.

Hope this helps!
