Arithmetic operators are used in daily life, like adding , subtracting, multiplying , dividing etc. The arithmetic operators are supported by JavaScript are : | ||||||||||||||||

<html>
<head> </head> <body> <script type=”text/javascript”> var a=40; var b = 50; var c= 5; var d; d = a+b document.write(“<br> Value of a is : “+a); document.write(“<br> Value of b is : “+b); document.write(“<br> Value of c is : “+c); document.write(“<br>Sum of a & b is : “+d); d=b-c; document.write(“<br>Difference of b & c is : “+d); d= a*c; document.write(“<br>Multiplication of a & c is : “+d); d=b/c; document.write(“<br>Quotient of Division of b & c is : “+d); d = a%c; document.write(“<br>Remainder of Division of a & c is : “+d); a++; b–; document.write(“<br>Value of A is now “+a); document.write(“<br>Value of b is now “+b); </script > </body> </html> |

Understanding the program: | ||||||||||||||||
Variable d store the result of every arithmetic operation with the two operands and displays the result. Division operator (/) returns the quotient of the division like 40/5= 8 but modulus (%) returns the remainder of the division like 40%5 = 0.the value of a will get increment with one a++ is equal to a=a+1and b– is equal to b = b-1. so the value of a was 40 it got incremented with one and became 41 while the value of b was 50 and got decremented with one and became 49. | ||||||||||||||||
Output is: | ||||||||||||||||
Value of a is: 40 Value of b is: 50 Value of c is: 5 Sum of a & b is: 90 Difference of b & c is: 45 Multiplication of a & c is: 200 Quotient of Division of b & c is: 10 Remainder of Division of a & c is: 0 Value of A is now 41 Value of b is now 49 |
