+
+Create a function that takes in an integer. This function should return the given `integer + 7` if the integer is less than `10`. If the integer is greater than or equal to `10`, it should return the given `integer - 3`.
+
+The name of the function should be `addOrSubtract`.
+
+# --hints--
+
+You should have a function called `addOrSubtract`.
+
+```js
+assert.isFunction(addOrSubtract);
+```
+
+Your function should take in an integer as an argument.
+
+```js
+assert.match(addOrSubtract.toString(), /\s*addOrSubtract\(\s*\w+\s*\)/);
+```
+
+You should return the given integer + 7 if the integer is less than 10.
+
+```js
+assert.strictEqual(addOrSubtract(5), 12);
+```
+
+You should return the given integer - 3 if the integer is greater than or equal to 10.
+
+```js
+assert.strictEqual(addOrSubtract(10), 7);
+```
