title: Import a Default Export
challengeType: 1
---
## Description
In the last challenge, you learned about export default and its uses. It is important to note that, to import a default export, you need to use a different import syntax.
In the following example, we have a function, add, that is the default export of a file, "math_functions". Here is how to import it:
import add from "math_functions";
add(5,4); //Will return 9
The syntax differs in one key place - the imported value, add, is not surrounded by curly braces, {}. Unlike exported values, the primary method of importing a default export is to simply write the value's name after import.
## Instructions
In the following code, please import the default export, subtract, from the file "math_functions", found in the same directory as this file.
## Tests
```yml
tests:
- text: Properly imports export default method.
testString: getUserInput => assert(getUserInput('index').match(/import\s+subtract\s+from\s+"math_functions"/g), 'Properly imports export default method.');
```
## Challenge Seed
```js
"use strict";
subtract(7,4);
```
### Before Test
```js
window.require = function(str) {
if (str === 'math_functions') {
return function(a, b) {
return a - b;
}}};
```
## Solution
```js
