I'm stuck at JS course, Introduction to Objects I, 13.Function Review.

The error is: "Oops, try again. Your function multiply failed on inputs 0,0 where you returned NaN instead of 0".

here is my code:

```
// Accepts a number x as input and returns its square
var square = function (x) {
return x * x;
};
// Write the function multiply below
// It should take two parameters and return the product
var multiply = function(x, y) {
return x / y; };
```

thanks
