"title": "Find a Remainder with Modulus",
"description": [
"The modulus operator <code>%</code> gives the remainder of the division of two numbers.",
"<code>5 % 2</code> is <code>1</code> because",
"<code>Math.floor(5 / 2) === 2<br />2 * 2 === 4<br />5 - 4 === 1</code>",
"<strong>Example</strong><blockquote>5 % 2 = 1 because<br>Math.floor(5 / 2) = 2 (Quotient)<br>2 * 2 = 4<br>5 - 4 = 1 (Remainder)</blockquote>",
"<strong>Usage</strong>",
"Modulus can be helpful in creating alternating or cycling values. For example, in a loop an increasing variable <code>myVar % 2</code> will alternate between 0 and 1 as myVar goes between even and odd numbers respectively.",
"In Maths, a number can be checked even or odd by checking the remainder of division of the number by <code>2</code>. ",
"<blockquote>17 % 2 = 1 (17 is Odd)<br>48 % 2 = 0 (48 is Even)</blockquote>",
"<h4>Instructions</h4>",
"Set <code>remainder</code> equal to the remainder of 11 divided by 3 using the modulus operator."
"Set <code>remainder</code> equal to the remainder of <code>11</code> divided by <code>3</code> using the <dfn>modulus</dfn> operator."
