# HELP... HELP.. HELP WHAT DO I NEED TO DO!!!

people on treehouse are telling what to do, but i still cant get it. whats the answer please. what do I need to type in. I watched the video and everything. its no help

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

},
multiply: function(value) {

},
divide: function(value) {

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

To finish the calculator you need to write the functions for each of the other operations.

Use the syntax from the addition function and complete with the different operators.

ex:

``` subtract: function(value) {
this.sum -= value;
},
```

Hope that helps! PLUS

Here is part of it, you need to finish it one more....You can do it!

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

Thank you very much. this helped a lot. I passed.
