Hi, Ca anyone help me with this exercise?

I get a message

- List item

Once both functions have run, the `sum`

should be equal to `8`

but I dont know what exactly do I need to do

**Your code so far**

```
// Setup
let sum = 0;
function addThree() {
sum = sum + 3;
}
// Only change code below this line
function addFive() {
sum = sum + 5;
}
var result = addFive();
// Only change code above this line
```
