# How to Convert Negative Value into Positive in Javascript

In this tutorial, you will learn how to convert negative value into positive in javascript. There is no computation that can be done without numbers. The digits 0 through 9 are combined to form a number. For a newbie developer, it can be a bit tricky to convert negative value into positive.

There are numerous ways to convert negative value into positive. But for the sake of simplicity, we will make use of  `Math` object.  This object contains a lot of methods and properties which can help us in various mathematical operations. One of those methods is the `abs()` method.

The `abs()` method returns an absolute value of a number. The distance of a number from zero on the number line, independent of direction, yields the absolute value of the number. In plain English, an absolute value is what remains after removing any preceding negative sign from a number. The absolute value of -2 is 2.

In the following example, we have an input field in which we will enter a random negative number. Upon click of a button, we will convert negative value into a positive and display that on the screen.  Please have a look over the code example and the steps given below.

HTML & CSS

• We have 4 elements in the HTML file (`div``input``button`, and `h1`). The `div` element is just a wrapper for the rest of the elements.
• The `innerText` for the `button` element is `“Get”` and for the `h1` element, it is `“Result”`.
• We have done some basic styling using CSS and added the link to our `style.css` stylesheet inside the `head` element.
• We have also included our javascript file `script.js` with a `script` tag at the bottom.
```<!DOCTYPE html>
<html lang="en">

<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">

<body>

<div class="container">
<input type="number" placeholder="Enter Number">
<button>Get</button>
<h1>Result</h1>
</div>

<script src="script.js"></script>
</body>

</html>```
```.container {
text-align: center;
}

button {
margin-top: 10px;
}

input {
display: block;
margin: 10px auto;
}

input[type=number]::-webkit-inner-spin-button,
input[type=number]::-webkit-outer-spin-button {
-webkit-appearance: none;
margin: 0;
}```

Javascript

• We have selected the `input` element, `button` element, and `h1` element using the `document.querySelector()` method and stored them in `input``btnGet`, and `output` variables respectively.
• We have attached a `click` event listener to the `button` element.
• In the event handler function, we are storing the value of the `input` element in the `num` variable.
• We are calling the `abs()` method to get the absolute of `num` and storing it in the `result` variable.
• We are displaying the `result` in the `h1` element using the `innerText` property.
```let input = document.querySelector("input");
let btnGet = document.querySelector("button");
let output = document.querySelector("h1");
