# Kotlin Program to Add Two Numbers

In this program, we will learn to code the Kotlin Program to Add Two Numbers. Let’s understand How to add two numbers in Kotlin Programming Language.

We will be using two different ways to perform this task. They are as follows:

1. Using Standard Method
2. Using User Input

Let’s see the code of the Kotlin Program to Add Two Numbers.

## Kotlin Program to Add Two Numbers

```// Kotlin Program to Add Two Numbers
fun main() {
var first = 10;
var second = 20;

var sum = first + second;

println("Sum of Two Numbers is "+sum);
}```

Output

``Sum of Two Numbers is 30``

## Kotlin Program to Add Two NumbersTaking User Input

Now, let’s the code of the Kotlin Program to Add Two Numbers by taking the numbers as input from the user.

```// Kotlin Program to Add Two Numbers

import java.util.Scanner;

fun main(args: Array<String>) {

var sc = Scanner(System.`in`);

println("Enter First Number : ");
var first = sc.nextInt();

println("Enter Second Number : ");
var second = sc.nextInt();

var sum = first + second;

println("Sum of Two Numbers is "+sum);
}```

Output

``````Enter First Number : 10
Enter Second Number : 20
Sum of Two Numbers is 30``````

## How Does This Program Work ?

```    var sc = Scanner(System.`in`);

println("Enter First Number : ");
var first = sc.nextInt();

println("Enter Second Number : ");
var second = sc.nextInt();```

In this program, we take the input of two integer numbers from the user, using the Scanner class in Kotlin. We import the Scanner Class using `import java.util.Scanner;`

`var sum = first + second;`

Then, using the addition arithmetic operator “+”, we calculate the sum of the two numbers.

`    println("Sum of Two Numbers is "+sum);`

Then, we print the sum of the two numbers using the `println() method in Kotlin.`
