Finding a Remainder in JavaScript


The remainder operator % gives the remainder of the division of two numbers.

Example

5 % 2 = 1 because
Math.floor(5 / 2) = 2 (Quotient)
2 * 2 = 4
5 - 4 = 1 (Remainder)

Usage
In mathematics, a number can be checked even or odd by checking the remainder of the division of the number by 2.

17 % 2 = 1 (17 is Odd)
48 % 2 = 0 (48 is Even)

Note
The remainder operator is sometimes incorrectly referred to as the "modulus" operator. It is very similar to modulus, but does not work properly with negative numbers.

Instructions

Set remainder equal to the remainder of 11 divided by 3 using the remainder (%) operator.
