# C# Arithmetic Operators In this chapter you will learn:
• What is operator in C#?
• What is Arithmetic Operator?
• How to use Arithmetic operator in program?
• What is Escape Character and how to use it?

Operators are a very useful thing in computing value. While writing a program, you need various types of operators to calculate the value. These operators are categorized as different categories in C sharp tutorial that performs specific task ex. The C# arithmetic operator performs the basic calculation as add, subtraction, multiplication, division, and modulus whereas other operators perform a different kind of task. You will learn one by one all these operators in few next chapters.

Arithmetic Operators are used for basic mathematical calculation in C# programming. The list of Arithmetic Operators is given below:

### Arithmetic Operators:

Operator Description Examples
- Subtract numbers X=num1-num2
* Multiply numbers X=num1*num2
/ Divide numbers X=num1/num2
% Divide two numbers and returns reminder X=22%10 then X will be X=2

```using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace Arithmetic_Operators
{
class Program
{
static void Main(string[] args)
{
int num1, num2;
float div;

//Accepting Values from users
Console.Write("Enter first number\t\t");

Console.Write("\n\nEnter second number\t\t");

//Processing Values
//Used + operator for adding values
//Used - operator for subtracting values
sub = num1 - num2;
//Used * operator for multiplying values
mul = num1 * num2;
//Used / operator for dividing values
div = (float)num1 / num2;

//Displaying Output
Console.WriteLine("\n\n=====================\n");
Console.WriteLine("Subtraction\t\t{0}", sub);
Console.WriteLine("Multiplication\t\t{0}", mul);
Console.WriteLine("Division\t\t{0}", div);
Console.WriteLine("\n=======================\n");

}
}
}```

#### Output

```Enter first number   15
Enter second number   12
=====================
Subtraction   3
Multiplication   180
Division   1.25
=======================

Note: \t,\n these are the special characters in C# that is known as Escape Characters. It is used for special purpose such as inserting line break, backspace etc.

### List of Escape Characters:

Escape Characters Description
\’ Used for single quotation mark
\" Used for double quotation mark
\\ Used for backslash
\0 Null
