# Learn Basic Algorithmic Thinking by Building a Number Sorter - Step 44

### Tell us what’s happening:

Here’s my code:

``````  const sortedValues = inputValues.sort((a, b) => {
if (a < 0 && b > 0) {
return b - a;
} else if (a > 0 && b < 0) {
return a - b;
} else {
return 0;
}
});
``````

I wonder what I’m doing wrong here. I needed to return a subtraction entity, so I tried returning one.

### Your code so far

``````<!-- file: index.html -->

``````
``````/* file: styles.css */

``````
``````/* file: script.js */
// User Editable Region

const sortedValues = inputValues.sort((a, b) => {
if (a < 0 && b > 0) {
return b - a;
} else if (a > 0 && b < 0) {
return a - b;
} else {
return 0;
}
});

“…return a single subtraction calculation using `a` and `b` that will correctly sort the numbers”

You added a lot more than a single subtraction calculation. I would reset the step to get the original code back. You don’t need an `if/else` statements. Only add exactly what the instructions ask and no more:

“return a single subtraction calculation”

Now I finally got it.
