It is part of the Order of Operations, a collection of rules that gives a sequence for simplifying <a class=\"ylist\" href=\"..\/addition-subtraction-multiplication-and-division\/\">mathematical operations<\/a>. It is used when an expression or equation has more than one operation. According to the <a class=\"ylist\" href=\"..\/order-of-operations\/\">order of operations<\/a>, all multiplication or division must occur before addition or subtraction. For example, the expression \\(6+4\u00d75\\) involves addition and multiplication. According to MDAS, simplify the multiplication portion of the expression before adding. Since \\(4\u00d75\\) equals 20, rewrite the expression as \\(6+20\\), which equals 26.<\/p>\n<p><img decoding=\"async\" class=\"aligncenter size-full wp-image-215971\" style=\"box-shadow: 1.5px 1.5px 3px gray;\" role=\"img\" src=\"https:\/\/www.mometrix.com\/academy\/wp-content\/uploads\/2025\/01\/MDAS@300x-scaled.webp\" alt=\"\" width=\"\" height=\"\" \/><\/p>\n<h2><span id=\"Why_do_we_use_this_system\" class=\"m-toc-anchor\"><\/span>Why do we use this system?<\/h2>\n<p>Recall that multiplication is repeated addition, which means multiplication is more powerful than addition. And division is repeated subtraction, which means division is more powerful than subtraction. Mathematicians developed the Order of Operations to simplify multiple operations in the order of their relative power.<\/p>\n<h2><span id=\"How_to_simplify_expressions\" class=\"m-toc-anchor\"><\/span>How to simplify expressions<\/h2>\n<p>Since multiplication and division are equally powerful, evaluate these two operations simultaneously, working from left to right.

Today we are going to talk about <strong>MDAS<\/strong>. This acronym may look a little familiar because it is a part of the order of operations (PEMDAS). <\/p>\n<p>PEMDAS stands for: parentheses, exponents, multiplication, division, addition, and subtraction. MDAS is just this final part right here. It tells you in what order to perform operations in an expression.<\/p>\n<p><img decoding=\"async\" src=\"https:\/\/www.mometrix.com\/academy\/wp-content\/uploads\/2025\/01\/MDAS@300x-scaled.webp\" alt=\"\" width=\"\" height=\"\" class=\"aligncenter size-full wp-image-215971\"  role=\"img\"  style=\"box-shadow: 1.5px 1.5px 3px gray;\" \/><\/p>\n<p>We want to complete all of the multiplication and division in order from left to right and then all of the addition and subtraction in order from left to right. It&#8217;s important that you group multiplication and division together and addition and subtraction together, because you can multiply and divide in any order, as long as it comes before addition and subtraction. And then the same thing with this\u2014you can add and subtract in any order (typically you go from left to right).<\/p>\n<p>So let&#8217;s try a few examples.<\/p>\n<div class=\"examplesentence\">\\(84-8\\div 2\\times 3\\)<\/div>\n<p>\n&nbsp;<br \/>\nFirst, look for any multiplication or division. Here we have both, so we need to simplify them from left to right. Start by dividing 8 by 2.<\/p>\n<div class=\"examplesentence\">\\(84-4\\times 3\\)<\/div>\n<p>\n&nbsp;<br \/>\nThen, multiply 4 and 3.<\/p>\n<div class=\"examplesentence\">\\(84-12\\)<\/div>\n<p>\n&nbsp;<br \/>\nFinally, perform any addition or subtraction. Subtract 12 from 84.<\/p>\n<div class=\"examplesentence\">\\(84-12=72\\)<\/div>\n<p>\n&nbsp;<br \/>\nSo, this expression simplifies to 72.<\/p>\n<p>Let\u2019s try another one!<\/p>\n<div class=\"examplesentence\">\\(16+8\\times 4-9\\div 3\\)<\/div>\n<p>\n&nbsp;<br \/>\nStart by simplifying any multiplication or division in order from left to right. First, multiply 8 and 4.<\/p>\n<div class=\"examplesentence\">\\(16+32-9\\div 3\\)<\/div>\n<p>\n&nbsp;<br \/>\nThen, divide 9 by 3.<\/p>\n<div class=\"examplesentence\">\\(16+32-3\\)<\/div>\n<p>\n&nbsp;<br \/>\nFrom here, simplify addition and subtraction in order from left to right. Add 16 and 32.<\/p>\n<div class=\"examplesentence\">\\(48-3\\)<\/div>\n<p>\n&nbsp;<\/p>\n<p>Finally, subtract 3 from 48.<\/p>\n<div class=\"examplesentence\">\\(48-3=45\\)<\/div>\n<p>\n&nbsp;<\/p>\n<p>So, the answer is 45.<\/p>\n<p>Let\u2019s try one last problem together before we go. <\/p>\n<div class=\"examplesentence\">\\(18\\div 3-2+4\\times 9-11\\)<\/div>\n<p>\n&nbsp;<br \/>\nStart by simplifying any multiplication or division, in order from left to right. First, divide 18 by 3.<\/p>\n<div class=\"examplesentence\">\\(6-2+4\\times 9-11\\)<\/div>\n<p>\n&nbsp;<br \/>\nThen, multiply 4 and 9.<\/p>\n<div class=\"examplesentence\">\\(6-2+36-11\\)<\/div>\n<p>\n&nbsp;<br \/>\nFrom here, simplify addition and subtraction in order from left to right. Subtract 2 from 6.<\/p>\n<div class=\"examplesentence\">\\(4+36-11\\)<\/div>\n<p>\n&nbsp;<br \/>\nThen, add 4 and 36.<\/p>\n<div class=\"examplesentence\">\\(40-11\\)<\/div>\n<p>\n&nbsp;<br \/>\nFinally, subtract 11 from 40.<\/p>\n<div class=\"examplesentence\">\\(40-11=29\\)<\/div>\n<p>\n&nbsp;<br \/>\nAnd there you have it!
