How to Use MDAS

What is MDAS?

MDAS stands for Multiplication, Division, Addition, and Subtraction. It is part of the Order of Operations, a collection of rules that gives a sequence for simplifying mathematical operations . It is used when an expression or equation has more than one operation. According to the order of operations , all multiplication or division must occur before addition or subtraction. For example, the expression \(6+4×5\) involves addition and multiplication. According to MDAS, simplify the multiplication portion of the expression before adding. Since \(4×5\) equals 20, rewrite the expression as \(6+20\), which equals 26.

Why do we use this system?

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.

How to simplify expressions

Since multiplication and division are equally powerful, evaluate these two operations simultaneously, working from left to right. Once all multiplication and division operations are simplified, evaluate addition and subtraction. Since addition and subtraction are equally powerful, evaluate these two operations simultaneously, working from left to right.

\(7-3+8\times5\)

This expression involves subtraction, addition, and multiplication. According to MDAS, simplify all multiplication or division before adding or subtracting. Therefore, start by simplifying \(8×5\).

\(\mathbf{7-3}+40\)

The two operations remaining in the expression are subtraction and addition. Since these operations are equal in power, read the expression from left to right and simplify the first operation, which is \(7-3\).

\(\mathbf{4+40}\)

Next, solve \(4+40\).

This means that \(7-3+8×5\) can be simplified to 44.

\(24\div4\times3\)

This expression involves division and multiplication. Since both operations are equal in power, read the expression from left to right and simplify the first operation, which is \(24÷4\).  Since \(24÷4=6\), rewrite the expression using 6.

\(\mathbf{6\times3}\)

Next, solve \(6×3\).

\(\mathbf{18}\)

This means that \(24÷4×3\) can be simplified to 18.

\(6+10×2÷4\)

This expression involves addition, multiplication, and division. According to MDAS, simplify all multiplication or division before adding or subtracting. Reading the expression from left to right, start by multiplying \(10×2\). Since \(10×2=20\), rewrite the expression using 20.

\(6+\mathbf{20\div4}\)

The two operations remaining in the expression are addition and division. According to MDAS, simplify all multiplication or division before adding or subtracting. Therefore, simplify \(20÷4\).

\(\mathbf{6+5}\)

Next, solve \(6+5\).

This means that \(6+10×2÷4\) can be simplified to 11.

\(5+81÷9×3-7\)

his expression involves addition, division, multiplication, and subtraction. According to MDAS, simplify all multiplication or division before adding or subtracting. Reading the expression from left to right, start by simplifying \(81÷9\).

\(5+\mathbf{9×3}-7\)

The three operations remaining in the expression are addition, multiplication, and subtraction. According to MDAS, simplify all multiplication or division before adding or subtracting. Therefore, simplify \(9×3\).

\(\mathbf{5+27} -7\)

The two operations remaining in the expression are addition and subtraction. Since both operations are equal in power, read the expression from left to right and simplify the first operation, which is \(5+27\).

\(\mathbf{32-7}\)

Next, solve \(32-7\).

This means that \(5+81÷9×3-7\) can be simplified to 25.

Hello! Today we are going to talk about MDAS . This acronym may look a little familiar because it is a part of the order of operations (PEMDAS). So PEMDAS stands for: parentheses, exponents, multiplication, division, addition, and subtraction. So MDAS is just this final part right here. It tells you in what order to perform operations in an expression. So we first have M and D, and then we have A and S. addition and subtraction when you simplify an expression. So, 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’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—you can add and subtract in any order (typically you go from left to right).

So let’s try a few examples.

First, 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.

Then, multiply 4 and 3.

Finally, perform any addition or subtraction. Subtract 12 from 84.

So, this expression simplifies to 72.

Let’s try another one!

Start by simplifying any multiplication or division in order from left to right. First, multiply 8 and 4.

Then, divide 9 by 3.

From here, simplify addition and subtraction in order from left to right. Add 16 and 32.

Finally, subtract 3 from 48.

So, the answer is 45.

Let’s try one last problem together before we go.

Start by simplifying any multiplication or division, in order from left to right. First, divide 18 by 3.

Then, multiply 4 and 9.

From here, simplify addition and subtraction in order from left to right. Subtract 2 from 6.

Then, add 4 and 36.

Finally, subtract 11 from 40.

And there you have it! I hope this video on MDAS was helpful. Thanks for watching, and happy studying!

MDAS Practice Questions

  Simplify the following using MDAS:

\(4+3×1+6-1\)

MDAS is part of the Order of Operations (PEMDAS):

Parentheses Exponents Multiply Divide Add Subtract

Multiplication and division need to be completed before addition and subtraction. For this example, the first step is \(3×1\).

\(4+3+6-1\)

From here, only addition and subtraction are left, so simply move from left to right. This simplifies to \(12\).

\(60×2+5-3+8×6-1\)

Multiplication and division need to be completed before addition and subtraction. For this example, the first step is \(60×2\), then \(8×6\). This leaves \(120+5-3+48-1\). From here, only addition and subtraction are left, so work from left to right. This simplifies to \(169\).

\(16÷2÷4+4×2-16×4\)

Multiplication and division need to be completed before addition and subtraction. For this example, the first step is \(16÷2÷4\). Working from left to right for this section, you are left with \(2\). Now, simplify \(4×2\) and \(16×4\). Now, the multiplication and division step is complete. \(2+8-64\)

From here, move on to addition and subtraction. Simplifying from left to right results in \(-54\).

\(24÷6+1+8+3×(-4)-11\)

Multiplication and division need to be completed before addition and subtraction. For this example, the first step is \(24÷6\) and \(3×-4\). Now we have \(4+1+8+(-12)-11\), which simplifies to \(-10\).

\(7+3-2.5×(-3)-0.5+3\)

Multiplication and division need to be completed before addition and subtraction. For this example, the first step is to simplify \(-2.5×(-3)\), which is \(7.5\). Rewrite the expression as \(7+3+7.5-0.5+3\), which simplifies to \(20\).

PEMDAS Help

Press 'H' from the main screen to show this help screen. Click on the headers to see the individual sections. Click the × button or outside the help screen to exit.

This is an online calculator that can toggle between MDAS and carrying out calculations as they are being entered. When MDAS is on, order of operations will be followed. For example, 3 + 2 * 5 = 13, as the multiplication is calculated before the addition. When MDAS is off, a subtotal will be calculated and displayed continuously as calculations are entered. For example, 3 + 2 * 5 = 25, as the operations are calculated in the order they are entered.

Display - left section

The 3 indicators on the left are:

Display - right section

There is a limit of 8 digits; accordingly, the maximum result your calculation can return is 99,999,999 and the minimum value it can return is -99,999,999. Results outside these limits will cause the calculator to error out. Also please note that due to the display limits, precision will be an issue past 7 decimal points.

MDAS toggle button

The MDAS ( M ultiplication, D ivision, A ddition, and S ubtraction) toggle button determines whether calculations will follow order of operations, or be calculated continuously. When MDAS is on, order of operations will be followed. For example, 3 + 2 * 5 = 13, as the multiplication is calculated before the addition. When MDAS is off, a subtotal will be calculated and displayed continuously as calculations are entered. For example, 3 + 2 * 5 = 25, as the operations are calculated in the order they are entered. Note that only the '+', '-', '×' and '÷' operators are affected by the MDAS setting. Toggling the button will clear all running totals, calculations, and the current display value. If you need to carry a value between settings, use the memory functions.

ON/C button

Press this button once to set the current display value to 0. Press it a second time to clear all calculations/running totals.

Operations buttons

When MDAS is on, the operations buttons can be pressed more than once in succession to operate with the current display value. For example 3+= would return 6 (3 + 3). 3++= would return 9 (3 + 3 + 3). 3++**-= would return 30 (3 + 3 + 3 * 3 * 3 - 3). Pressing the equals button more than once does nothing. When MDAS is off, pressing the operations buttons more than once would cause the operation to be performed on the current display value. For example 3++**-= would return 0 (since the last display value of 20736 would be subtracted by itself). Pressing equals more than once repeats the last operation. For example 3+2*5=== would return 625 (25 * 5 * 5).

'+/-', '%' and '√' buttons

The '+/-' button toggles the display value from positive to negative. You can see the current status on the indicator. The '√' button calculates the square root of the current display number in place. The '%' button calculates the percent of the last displayed number in place. For example, 12+10% would display 1.2. If there is no last displayed number, it will return the display number divided by 100. For example 10% would return 0.1. Neither the '√' or the '%' buttons are affected by the MDAS setting.

Memory buttons

The three buttons which store and retrieve a number from memory are M+, M-, and MRC. You can see if the memory has a non-zero value by looking at the indicator. M+ adds the current display value to memory. M- subtracts the current display value from memory. If adding or subtracting the current value to the memory value would cause an overflow, the addition/subtraction will not be made and the calculator will error out. When pressed once, pressing MRC R ecalls the memory value. Pressing MRC a second time will C lear the memory.

The PEMDAS Rule: Understanding Order of Operations

General Education

Everyone who's taken a math class in the US has heard the acronym "PEMDAS" before. But what does it mean exactly? Here, we will explain in detail the PEMDAS meaning and how it's used before giving you some sample PEMDAS problems so you can practice what you've learned.

PEMDAS Meaning: What Does It Stand For?

PEMDAS is an acronym meant to help you remember the order of operations used to solve math problems. It's typically pronounced "pem-dass," "pem-dozz," or "pem-doss."

Here's what each letter in PEMDAS stands for:

• P arentheses
• M ultiplication and D ivision
• A ddition and S ubtraction

The order of letters shows you the order you must solve different parts of a math problem , with expressions in parentheses coming first and addition and subtraction coming last.

Many students use this mnemonic device to help them remember each letter: P lease E xcuse M y D ear A unt S ally .

In the United Kingdom and other countries, students typically learn PEMDAS as BODMAS . The BODMAS meaning is the same as the PEMDAS meaning — it just uses a couple different words. In this acronym, the B stands for "brackets" (what we in the US call parentheses) and the O stands for "orders" (or exponents). Now, how exactly do you use the PEMDAS rule? Let's take a look.

How Do You Use PEMDAS?

PEMDAS is an acronym used to remind people of the order of operations.

This means that you don't just solve math problems from left to right; rather, you solve them in a predetermined order that's given to you via the acronym PEMDAS . In other words, you'll start by simplifying any expressions in parentheses before simplifying any exponents and moving on to multiplication, etc.

But there's more to it than this. Here's exactly what PEMDAS means for solving math problems:

• Parentheses: Anything in parentheses must be simplified first
• Exponents: Anything with an exponent (or square root) must be simplified after everything in parentheses has been simplified
• Multiplication and Division: Once parentheses and exponents have been dealt with, solve any multiplication and division from left to right
• Addition and Subtraction: Once parentheses, exponents, multiplication, and division have been dealt with, solve any addition and subtraction from left to right

If any of these elements are missing (e.g., you have a math problem without exponents), you can simply skip that step and move on to the next one.

Now, let's look at a sample problem to help you understand the PEMDAS rule better:

4 (5 − 3)² − 10 ÷ 5 + 8

You might be tempted to solve this math problem left to right, but that would result in the wrong answer! So, instead, let's use PEMDAS to help us approach it the correct way.

We know that parentheses must be dealt with first. This problem has one set of parentheses: (5 − 3). Simplifying this gives us 2 , so now our equation looks like this:

4 (2)² − 10 ÷ 5 + 8

The next part of PEMDAS is exponents (and square roots). There is one exponent in this problem that squares the number 2 (i.e., what we found by simplifying the expression in the parentheses).

This gives us 2 × 2 = 4. So now our equation looks like this:

4 (4) − 10 ÷ 5 + 8    OR    4 × 4 − 10 ÷ 5 + 8

Next up is multiplication and division from left to right . Our problem contains both multiplication and division, which we'll solve from left to right (so first 4 × 4 and then 10 ÷ 5). This simplifies our equation as follows:

Finally, all we need to do now is solve the remaining addition and subtraction from left to right :

The final answer is 22. Don't believe me? Insert the whole equation into your calculator (written exactly as it is above) and you'll get the same result!

Sample Math Problems Using PEMDAS + Answers

See whether you can solve the following four problems correctly using the PEMDAS rule. We'll go over the answers after.

Sample PEMDAS Problems

11 − 8 + 5 × 6

8 ÷ 2 (2 + 2)

7 × 4 − 10 (5 − 3) ÷ 2²

√25 (4 + 2)² − 18 ÷ 3 (3 − 1) + 2³

Answer Explanations

Here, we go over each problem above and how you can use PEMDAS to get the correct answer.

#1 Answer Explanation

This math problem is a fairly straightforward example of PEMDAS that uses addition, subtraction, and multiplication only , so no having to worry about parentheses or exponents here.

We know that multiplication comes before addition and subtraction , so you'll need to start by multiplying 5 by 6 to get 30:

11 − 8 + 30

Now, we can simply work left to right on the addition and subtraction:

11 − 8 + 30 3 + 30 = 33

This brings us to the correct answer, which is 33 .

#2 Answer Explanation

If this math problem looks familiar to you, that's probably because it went viral in August 2019 due to its ambiguous setup . Many people argued over whether the correct answer was 1 or 16, but as we all know, with math there's (almost always!) only one truly correct answer.

So which is it: 1 or 16?

Let's see how PEMDAS can give us the right answer. This problem has parentheses, division, and multiplication. So we'll start by simplifying the expression in the parentheses, per PEMDAS:

While most people online agreed up until this point, many disagreed on what to do next: do you multiply 2 by 4, or divide 8 by 2?

PEMDAS can answer this question: when it comes to multiplication and division, you always work left to right. This means that you would indeed divide 8 by 2 before multiplying by 4.

It might help to look at the problem this way instead, since people tend to get tripped up on the parentheses (remember that anything next to a parenthesis is being multiplied by whatever is in the parentheses):

Now, we just solve the equation from left to right:

8 ÷ 2 × 4 4 × 4 = 16

The correct answer is 16. Anyone who argues it's 1 is definitely wrong — and clearly isn't using PEMDAS correctly!

#3 Answer Explanation

Things start to get a bit trickier now.

This math problem has parentheses, an exponent, multiplication, division, and subtraction. But don't get overwhelmed — let's work through the equation, one step at a time.

First, per the PEMDAS rule, we must simplify what's in the parentheses :

7 × 4 − 10 (2) ÷ 2²

Easy peasy, right? Next, let's simplify the exponent :

7 × 4 − 10 (2) ÷ 4

All that's left now is multiplication, division, and subtraction. Remember that with multiplication and division, we simply work from left to right:

7 × 4 − 10 (2) ÷ 4 28 − 10 (2) ÷ 4 28 − 20 ÷ 4 28 − 5

Once you've multiplied and divided, you just need to do the subtraction to solve it:

28 − 5 = 23

This gives us the correct answer of 23 .

#4 Answer Explanation

This problem might look scary, but I promise it's not! As you long as you approach it one step at a time using the PEMDAS rule , you'll be able to solve it in no time.

Right away we can see that this problem contains all components of PEMDAS : parentheses (two sets), exponents (two and a square root), multiplication, division, addition, and subtraction. But it's really no different from any other math problem we've done.

First, we must simplify what's in the two sets of parentheses:

√25 (6)² − 18 ÷ 3 (2) + 2³

Next, we must simplify all the exponents — this includes square roots, too :

5 (36) − 18 ÷ 3 (2) + 8

Now, we must do the multiplication and division from left to right:

5 (36) − 18 ÷ 3 (2) + 8 180 − 18 ÷ 3 (2) + 8 180 − 6 (2) + 8 180 − 12 + 8

Finally, we solve the remaining addition and subtraction from left to right:

180 − 12 + 8 168 + 8 = 176

This leads us to the correct answer of 176 .

Order of Operations PEMDAS

"Operations" mean things like add, subtract, multiply, divide, squaring, etc. If it isn't a number it is probably an operation.

But, when you see something like ...

7 + (6 × 5 2 + 3)

... what part should you calculate first? Start at the left and go to the right? Or go from right to left?

Warning: Calculate them in the wrong order, and you can get a wrong answer !

So, long ago people agreed to follow rules when doing calculations, and they are:

Order of Operations

Do things in Parentheses First

Exponents (Powers, Roots) before Multiply, Divide, Add or Subtract

Multiply or Divide before you Add or Subtract

Otherwise just go left to right

How Do I Remember It All ... ? PEMDAS !

Divide and Multiply rank equally (and go left to right).

Add and Subtract rank equally (and go left to right)

So do it this way:

After you have done "P" and "E", just go from left to right doing any "M" or "D" as you find them.

Then go from left to right doing any "A" or "S" as you find them.

You can remember by saying " P lease E xcuse M y D ear A unt S ally".

You may prefer GEMS ( G rouping, E xponents, M ultiply or Divide, Add or S ubtract). In the UK they say BODMAS (Brackets, Orders, Divide, Multiply, Add, Subtract). In Canada they say BEDMAS (Brackets, Exponents, Divide, Multiply, Add, Subtract). It all means the same thing! It doesn't matter how you remember it, just so long as you get it right.

Example: How do you work out 3 + 6 × 2 ?

M ultiplication before A ddition:

First 6 × 2 = 12 , then 3 + 12 = 15

Example: How do you work out (3 + 6) × 2 ?

P arentheses first:

First (3 + 6) = 9 , then 9 × 2 = 18

Example: How do you work out 12 / 6 × 3 / 2 ?

M ultiplication and D ivision rank equally, so just go left to right:

First 12 / 6 = 2 , then 2 × 3 = 6 , then 6 / 2 = 3

A practical example:

Example: Sam threw a ball straight up at 20 meters per second, how far did it go in 2 seconds?

Sam uses this special formula that includes the effects of gravity:

height = velocity × time − (1/2) × 9.8 × time 2

Sam puts in the velocity of 20 meters per second and time of 2 seconds:

height = 20 × 2 − (1/2) × 9.8 × 2 2

Now for the calculations!

The ball reaches 20.4 meters after 2 seconds

Exponents of Exponents ...

What about this example?

Exponents are special: they go top-down (do the exponent at the top first). So we calculate this way:

So 4 3 2 = 4 (3 2 ) , not (4 3 ) 2

And finally, what about the example from the beginning?

The order of operations is a rule that tells the correct sequence of steps for evaluating a math expression. 

M – ultiplication D – ivision A – ddition S – subtraction

Why does MDAS important in solving math problems?

• It ensures that people can all read and solve a problem in the same way. 
• Without a standard order of operations, formulas for real-world calculations in finance and science would be useless—and; 
• It would be difficult to know if you were getting the right answer on a math test!

This is a fantastic bundle which includes everything you need to know about Basic Order of Operations (MDAS) across 21 in-depth pages.

Each ready to use worksheet collection includes 10 activities and an answer guide. Not teaching common core standards ? Don’t worry! All our worksheets are completely editable so can be tailored for your curriculum and target audience.
