I’m not sure if I’m doing this right at all as I’m a little confused by it but I somehow got everything ticked correct except one part which is the -2,2 not equaling undefined. Anyways what do you think the problem is?

```
// Setup
function abTest(a, b) {
// Only change code below this line
if (a && b < 0) {
return undefined;
}
// Only change code above this line
return Math.round(Math.pow(Math.sqrt(a) + Math.sqrt(b), 2));
}
// Change values below to test your code
abTest(2,2);
```
