# --description--

In the last challenge, you learned about `export default` and its uses. To import a default export, you need to use a different `import` syntax. In the following example, `add` is the default export of the `math_functions.js` file. Here is how to import it:

```js
import add from "./math_functions.js";
```

The syntax differs in one key place. The imported value, `add`, is not surrounded by curly braces (`{}`). `add` here is simply a variable name for whatever the default export of the `math_functions.js` file is. You can use any name here when importing a default.

# --instructions--

In the following code, import the default export from the `math_functions.js` file, found in the same directory as this file. Give the import the name `subtract`.

# --hints--

You should properly import `subtract` from `math_functions.js`.

```js
assert(code.match(/import\s+subtract\s+from\s+('|")\.\/math_functions\.js\1/g));
```

# --seed--

## --seed-contents--

```js

// Only change code above this line

subtract(7,4);
```

# --solutions--

```js
import subtract from "./math_functions.js";

subtract(7,4);
```
