# --description--
The <dfn>remainder</dfn> operator `%` gives the remainder of the division of two numbers.
**Example**
<blockquote>5 % 2 = 1 because<br>Math.floor(5 / 2) = 2 (Quotient)<br>2 * 2 = 4<br>5 - 4 = 1 (Remainder)</blockquote>
**Usage**
In mathematics, a number can be checked to be even or odd by checking the remainder of the division of the number by `2`.
<blockquote>17 % 2 = 1 (17 is Odd)<br>48 % 2 = 0 (48 is Even)</blockquote>
**Note**
The <dfn>remainder</dfn> operator is sometimes incorrectly referred to as the "modulus" operator. It is very similar to modulus, but does not work properly with negative numbers.
# --instructions--
Set `remainder` equal to the remainder of `11` divided by `3` using the <dfn>remainder</dfn> (`%`) operator.
# --hints--
The variable `remainder` should be initialized
```js
assert(/var\s+?remainder/.test(code));
```
The value of `remainder` should be `2`
```js
assert(remainder === 2);
```
You should use the `%` operator
```js
assert(/\s+?remainder\s*?=\s*?.*%.*;?/.test(code));
```
# --seed--
## --after-user-code--
```js
(function(y){return 'remainder = '+y;})(remainder);
```
## --seed-contents--
```js
// Only change code below this line
var remainder;
```
# --solutions--
```js
var remainder = 11 % 3;
```
