Arithmetic Operations on Numbers

In JavaScript we may use Arithmetic operators to perform arithmetic on numbers (literals or variables).

Operator Description
+ Addition
- Subtraction
* Multiplication
** Exponentiation
/ Division
% Modulus (Remainder)
++ Increment
-- Decrement

A typical arithmetic operation operates on two numbers.

  • The two numbers can be literals:
Example: var x = 1 + 7;
  • The two numbers can be variables:
Example: var x = n + m;
  • The two numbers can be variables:
Example: var x = (1 + 8) + n;

Operators and Operands

  • The numbers (in an arithmetic operation) are called operands.
  • The operation (to be performed between the two operands) is defined by an operator.

The addition operator (+) adds numbers:

Example:
var x = 7;
var y = 2;
var z = x + y;
// So z will store 9.

The subtraction operator (-) subtracts numbers:

Example:
var x = 7;
var y = 2;
var z = x - y;
// So z will store 5.

The multiplication operator (*) multiplies numbers:

Example:
var x = 7;
var y = 2;
var z = x * y;
// So z will store 14.

The division operator (/) divides numbers:

Example:
var x = 8;
var y = 2;
var z = x / y;
// So z will store 4.

The modulus operator (%) returns the division remainder.

Example:
var x = 7;
var y = 2;
var z = x % y;
// So z will store 1.

The increment operator (++) increments numbers.

Example:
var x = 5;
x++;
var z = x;
// So z will store 6.

The decrement operator (–) decrements numbers.

Example:
var x = 5;
x--;
var z = x;
// So z will store 4.

The exponentiation operator (**) raises the first operand to the power of the second operand.

Example:
var x = 5;
var z = x ** 2;
// So z will store 25.

Try the following example in the editor below.

You are given an integer N, print the value of N*N + N3 - N.

Sample Input:

2

Sample Output:

10
