# Program to find the sum and difference of two numbers

Last Updated : 29 Jan, 2024

Given two Integers A and B, your task is to find the sum and difference of two numbers.

Examples:

Input: A = 4, B = 9
Output: Sum = 13 and Difference = -5
Input: A = -3, B = -2
Output: Sum = -5 and Difference = -1

#### Approach:

The problem can be solved using arithmetic operators.

Operations on Numbers:

• Addition (+): This operation is used to add the inputs to get the output. For example, when 2 is added to 3 the resultant will be equal to the sum of both the numbers which is equal to 5, (2 + 3 = 5).
• Subtraction (-): This operation is used to subtract the inputs to get the result. For example, when 3 is subtracted by 2 the resultant will be equal to the difference of both the numbers which is equal to 1 (3 â€“ 2 = 1).

Step-by-step algorithm:

• Read A and B from the user
• Calculate the sum: result = A + B
• Calculate the difference: result = A – B
• Display the results.

Below is the implementation of the above approach:

## C++

 `#include ` `using` `namespace` `std;`   `int` `main()` `{` `    ``int` `A, B;` `    ``A = 4;` `    ``B = 9;` `    ``cout << "Sum of " << A << " and " << B << " = " << A + B` `         ``<< endl;` `    ``cout << "Difference of " << A << " and " << B << " = "` `         ``<< A - B << endl;` `}`

## Java

 `public` `class` `MainClass {` `    ``public` `static` `void` `main(String[] args) {` `        ``// Declaring and initializing variables A and B` `        ``int` `A, B;` `        ``A = ``4``;` `        ``B = ``9``;`   `        ``// Printing the sum of A and B` `        ``System.out.println(``"Sum of "` `+ A + ``" and "` `+ B + ``" = "` `+ (A + B));`   `        ``// Printing the difference of A and B` `        ``System.out.println(``"Difference of "` `+ A + ``" and "` `+ B + ``" = "` `+ (A - B));` `    ``}` `}`

## Python3

 `# Python code` `A ``=` `4` `B ``=` `9`   `# Printing the sum of A and B` `print``(f``"Sum of {A} and {B} = {A + B}"``)`   `# Printing the difference of A and B` `print``(f``"Difference of {A} and {B} = {A - B}"``)`

## C#

 `using` `System;`   `class` `MainClass` `{` `    ``public` `static` `void` `Main(``string``[] args)` `    ``{` `        ``int` `A, B;` `        ``A = 4;` `        ``B = 9;`   `        ``// Printing the sum of A and B` `        ``Console.WriteLine(\$``"Sum of {A} and {B} = {A + B}"``);`   `        ``// Printing the difference of A and B` `        ``Console.WriteLine(\$``"Difference of {A} and {B} = {A - B}"``);` `    ``}` `}`

## Javascript

 `let A, B;` `A = 4;` `B = 9;`   `console.log(``"Sum of "` `+ A + ``" and "` `+ B + ``" = "` `+ (A + B));` `console.log(``"Difference of "` `+ A + ``" and "` `+ B + ``" = "` `+ (A - B));`

Output

```Sum of 4 and 9 = 13
Difference of 4 and 9 = -5

```

Time Complexity: O(1)
Auxiliary Space: O(1)
