20 = 10 + 10

35 = 15 + 20

Example 1: How to add two numbers in Kotlin.

import java.util.Scanner

fun main(args: Array<String>) {

    var a: Int
    var b: Int
    var sum: Int

    var sc = Scanner(System.`in`)

    print("Enter two numbers:")
    a = sc.nextInt()
    b = sc.nextInt()

    sum = a + b

    println("Sum is:$sum")
}

Output:

Enter two numbers:10 20

Sum is:30

Example 2: Kotlin Program to Add Two Integers

fun main(args: Array<String>) {

    val first: Int = 10
    val second: Int = 20

    val sum = first + second

    println("The sum is: $sum")
}

When you run the program, the output will be:

The sum is: 30

In this program, similar to Java, two integers 10 and 20 are stored in integer variables first and second respectively. It is not mandatory to add :Int in the variable declaration, Kotlin automatically assigns a type (in this case Int).

Then, first and second are added using the + operator, and its result is stored in another variable sum.

Finally, sum is printed on the screen using println() function.
