title: Generate Random Whole Numbers with JavaScript

## Generate Random Whole Numbers with JavaScript
Heres the setup:
```javascript
var randomNumberBetween0and19 = Math.floor(Math.random() * 20);
function randomWholeNum() {
// Only change code below this line.
Math.floor(Math.random() * 10);
return Math.floor(Math.random());
}
```
We need to use ```Math.floor()``` with ```Math.random()``` to generate and return a random whole number between 0 and 9.
Putting ```Math.floor()``` and ```Math.random()``` together, this is what our code looks like:
```javascript
Math.floor(Math.random() * 10);
```
And we need change the value of ```return```:
```javascript
return Math.floor(Math.random());
```
Heres a full solution:
```javascript
var randomNumberBetween0and19 = Math.floor(Math.random() * 20);
function randomWholeNum() {
// Only change code below this line.

return Math.floor(Math.random()*10);
}
```
