**Tell us what’s happening:**

I have no idea where to go from here. This works with the all but the double parentheses arguments.

**Your code so far**

```
function addTogether() {
const args = Array.from(arguments);
return args.every((x, y, z) => typeof x === "number" && z.length === 2)
? args.reduce((a, b) => a + b)
: undefined;
}
addTogether(2,3);
```
