BODMAS or PEMDAS? The Math Rule Confusion Finally Solved

BODMAS and PEMDAS are two common ways to remember the correct order of mathematical operations.

Students often search for “BODMAS or PEMDAS” because different schools, textbooks, and countries may use different terms for the same basic rule. Seeing BODMAS in one place and PEMDAS in another can make the topic seem more complicated than it is.

BODMAS stands for Brackets, Orders, Division, Multiplication, Addition, and Subtraction. PEMDAS stands for Parentheses, Exponents, Multiplication, Division, Addition, and Subtraction.

The important point is that multiplication and division have the same priority. You normally solve them from left to right. Addition and subtraction also share the same priority.

For example:

6 + 4 × 2 = 14

First, multiply 4 × 2 to get 8. Then add 6 to get 14.

Understanding this rule helps students solve expressions correctly and avoid common mistakes caused by treating BODMAS or PEMDAS as a strict six-step sequence.

*BODMAS or PEMDAS : Quick Answer


BODMAS and PEMDAS describe essentially the same order of operations, but they use different words in their acronyms.

BODMAS means:

Brackets → Orders → Division → Multiplication → Addition → Subtraction

PEMDAS means:

Parentheses → Exponents → Multiplication → Division → Addition → Subtraction

The basic rule is:

Grouping symbols → Exponents/Orders → Multiplication and Division → Addition and Subtraction

Remember that multiplication and division are handled from left to right, rather than always doing multiplication before division.

Simple Example

8 + 2 × 3

First:

2 × 3 = 6

Then:

8 + 6 = 14

So, the correct answer is 14.

What Does BODMAS Mean?


BODMAS is a mnemonic that helps students remember the order in which mathematical operations are normally performed.

B : Brackets

Brackets group part of an expression that should be solved first.

Example:

5 × (2 + 3)

First:

2 + 3 = 5

Then:

5 × 5 = 25

O : Orders

Orders generally refer to powers, exponents, roots, and related operations.

Example:

2³ + 4

First:

2³ = 8

Then:

8 + 4 = 12

D : Division

Division is performed before addition and subtraction.

Example:

18 ÷ 3 + 2

First:

18 ÷ 3 = 6

Then:

6 + 2 = 8

M : Multiplication

Multiplication also comes before addition and subtraction.

Example:

7 + 3 × 2

First:

3 × 2 = 6

Then:

7 + 6 = 13

A : Addition

Addition is performed after multiplication and division.

S : Subtraction

Subtraction has the same priority as addition.

For expressions containing both addition and subtraction, work from left to right.

What Does PEMDAS Mean?


PEMDAS is another mnemonic used to remember the order of mathematical operations.

P : Parentheses

Parentheses group operations that should be completed together.

Example:

4 × (3 + 2)

First:

3 + 2 = 5

Then:

4 × 5 = 20

E : Exponents

Exponents represent powers.

Example:

3² + 5

First:

3² = 9

Then:

9 + 5 = 14

M : Multiplication

Multiplication has priority over addition and subtraction.

D : Division

Division has the same priority as multiplication.

This means PEMDAS does not require every multiplication operation to be completed before every division operation.

A : Addition

Addition is handled after multiplication and division.

S : Subtraction

Subtraction has the same priority as addition.

BODMAS vs PEMDAS: Basic Difference


The main difference between BODMAS and PEMDAS is the terminology used to describe grouping symbols and powers.

BODMASPEMDAS
BracketsParentheses
OrdersExponents
DivisionMultiplication
MultiplicationDivision
AdditionAddition
SubtractionSubtraction

“Brackets” and “parentheses” refer to grouping symbols. “Orders” and “exponents” relate to powers and similar operations.

The different letter order can sometimes cause confusion, but multiplication and division have equal priority, just as addition and subtraction have equal priority.

Is BODMAS the Same as PEMDAS?


Yes, BODMAS and PEMDAS are different memory aids for essentially the same order-of-operations principle.

Consider:

12 + 6 ÷ 3

First divide:

6 ÷ 3 = 2

Then add:

12 + 2 = 14

The result is 14 using either system.

The key is to understand the mathematical relationships between operations instead of treating each letter as a separate step that must always be completed before the next letter.

Why Do Multiplication and Division Have the Same Priority?


Why Do Multiplication and Division Have the Same Priority?

Multiplication and division belong to the same level of the order of operations.

Consider:

24 ÷ 6 × 2

Work from left to right:

24 ÷ 6 = 4

4 × 2 = 8

The answer is 8.

You should not automatically multiply first simply because M appears before D in PEMDAS.

Addition and subtraction follow the same principle.

Example:

15 − 5 + 3

Work from left to right:

15 − 5 = 10

10 + 3 = 13

The answer is 13.

The Easy BODMAS and PEMDAS Rule


The easiest way to remember the rule is to group operations by priority instead of treating BODMAS or PEMDAS as six completely separate steps.

  1. Brackets or parentheses
  2. Orders or exponents
  3. Multiplication and division from left to right
  4. Addition and subtraction from left to right

This approach makes mathematical expressions easier to understand and helps prevent the most common mistakes.

How to Use BODMAS and PEMDAS Step by Step


The easiest way to solve a BODMAS or PEMDAS expression is to identify the highest-priority operation first and then work through the remaining operations carefully.

Step 1: Solve Brackets or Parentheses

Look for anything inside brackets or parentheses.

Example:

6 × (4 + 2)

First:

4 + 2 = 6

Then:

6 × 6 = 36

Step 2: Solve Orders or Exponents

Next, calculate powers or exponents.

Example:

3² + 5

First:

3² = 9

Then:

9 + 5 = 14

Step 3: Solve Multiplication and Division

Multiplication and division have the same priority.

Work from left to right.

Example:

20 ÷ 5 × 3

First:

20 ÷ 5 = 4

Then:

4 × 3 = 12

Step 4: Solve Addition and Subtraction

Addition and subtraction also have the same priority.

Work from left to right.

Example:

18 − 6 + 4

First:

18 − 6 = 12

Then:

12 + 4 = 16

BODMAS Examples With Answers


These examples show how BODMAS works with different combinations of operations.

Example 1: Multiplication Before Addition

7 + 5 × 2

First:

5 × 2 = 10

Then:

7 + 10 = 17

Example 2: Division Before Subtraction

20 − 12 ÷ 4

First:

12 ÷ 4 = 3

Then:

20 − 3 = 17

Example 3: Brackets First

4 × (6 − 2)

First:

6 − 2 = 4

Then:

4 × 4 = 16

Example 4: Exponents

2³ + 6 × 2

First:

2³ = 8

Then:

6 × 2 = 12

Finally:

8 + 12 = 20

PEMDAS Examples With Answers


PEMDAS follows the same basic process, using parentheses and exponents as its terminology.

Example 1

9 + 3 × 4

First:

3 × 4 = 12

Then:

9 + 12 = 21

Example 2

(9 + 3) × 4

First:

9 + 3 = 12

Then:

12 × 4 = 48

Example 3

5² − 4 × 3

First:

5² = 25

Then:

4 × 3 = 12

Finally:

25 − 12 = 13

BODMAS and PEMDAS With Fractions


Fractions do not change the basic order of operations, so brackets, exponents, multiplication, division, addition, and subtraction are still handled by priority.

Consider:

1/2 + 3 × 2

First:

3 × 2 = 6

Then:

1/2 + 6 = 6½

Example With Parentheses

2 × (1/2 + 3)

First solve the parentheses:

1/2 + 3 = 7/2

Then:

2 × 7/2 = 7

BODMAS and PEMDAS With Negative Numbers


Negative numbers follow the same order of operations, but parentheses can change the result significantly.

Consider:

−4 + 3 × 2

First:

3 × 2 = 6

Then:

−4 + 6 = 2

Now compare it with:

(−4 + 3) × 2

First:

−4 + 3 = −1

Then:

−1 × 2 = −2

The parentheses change the answer from 2 to −2.

Common BODMAS and PEMDAS Mistakes


Most mistakes happen when people misunderstand equal-priority operations or skip brackets and exponents.

Mistake 1: Multiplying Before Division Every Time

Consider:

16 ÷ 4 × 2

The correct method is left to right:

16 ÷ 4 = 4

4 × 2 = 8

Multiplication does not automatically come before division.

Mistake 2: Adding Before Subtracting Every Time

Consider:

15 − 5 + 2

Work from left to right:

15 − 5 = 10

10 + 2 = 12

Mistake 3: Ignoring Parentheses

Consider:

8 × (2 + 3)

Solve the parentheses first:

2 + 3 = 5

Then:

8 × 5 = 40

Mistake 4: Solving Everything From Left to Right

Not every expression should be calculated from the first number to the last.

Example:

4 + 5 × 2

Incorrect:

4 + 5 = 9
9 × 2 = 18 ❌

Correct:

5 × 2 = 10
4 + 10 = 14 ✅

*BODMAS vs PEMDAS in Different Countries


BODMAS and PEMDAS are used in different educational settings, but the underlying mathematical principle remains the same.

BODMAS is commonly seen in the UK and in many countries that follow British-style mathematics education.

PEMDAS is especially common in the United States.

Other variations also exist, such as BEDMAS, where the “E” represents exponents.

The wording may change, but the goal is the same: help students remember the correct order for solving mathematical expressions.

BODMAS or PEMDAS: Which One Should You Use?


Use the version taught by your school, teacher, textbook, or curriculum, but focus on understanding the actual order of operations.

If your textbook uses BODMAS, continue using BODMAS.

If your American mathematics class uses PEMDAS, use PEMDAS.

The important thing is not the acronym itself. The important rules are:

  • Grouping symbols are handled first.
  • Exponents or orders come next.
  • Multiplication and division are solved from left to right.
  • Addition and subtraction are solved from left to right.

This approach works even if you encounter a different acronym later.

BODMAS and PEMDAS Comparison Table


The following table shows how the two acronyms describe the same general mathematical process.

Mathematical LevelBODMASPEMDAS
GroupingBracketsParentheses
PowersOrdersExponents
Multiplication & DivisionLeft to rightLeft to right
Addition & SubtractionLeft to rightLeft to right

This is why knowing the priority levels is more useful than simply memorizing the letters.

Why Does PEMDAS Say Multiplication Before Division?


The wording of PEMDAS can make multiplication appear more important than division, but that is not the mathematical rule.

In PEMDAS, M and D have equal priority.

For example:

48 ÷ 6 × 2

Start from the left:

48 ÷ 6 = 8

Then:

8 × 2 = 16

Doing multiplication first would produce a different result, which is why the left-to-right rule matters.

Why Does BODMAS Say Division Before Multiplication?


BODMAS can create the opposite confusion because D appears before M, but division is not automatically performed before multiplication.

Consider:

48 × 2 ÷ 6

Work from left to right:

48 × 2 = 96

96 ÷ 6 = 16

You do not divide first simply because D appears before M in the word BODMAS.

The letters are a memory aid, not a strict sequence for equal-priority operations.

What Happens When There Are Multiple Operations?


When an expression contains several operations, apply the priority rules repeatedly until only the final answer remains.

Consider:

10 + 6 ÷ 2 × 3 − 4

First handle division and multiplication from left to right:

6 ÷ 2 = 3

Then:

3 × 3 = 9

Now the expression becomes:

10 + 9 − 4

Work from left to right:

10 + 9 = 19

19 − 4 = 15

So the answer is 15.

How to Avoid BODMAS and PEMDAS Mistakes


The best way to avoid mistakes is to write each calculation step clearly instead of trying to solve the entire expression mentally.

1. Look for Brackets

Check for parentheses or brackets before doing anything else.

2. Look for Powers

Identify exponents, squares, cubes, and similar operations.

3. Move Left to Right

For multiplication and division, start from the left and continue toward the right.

4. Check Addition and Subtraction

Handle addition and subtraction from left to right.

5. Review the Expression

After getting an answer, quickly check that no higher-priority operation was skipped.

This simple process is especially useful for students working through long expressions or exam questions.

BODMAS or PEMDAS in Real-Life Math


BODMAS and PEMDAS are useful whenever a calculation contains more than one mathematical operation.

You may use the order of operations in shopping, budgeting, measurements, schoolwork, business calculations, and everyday problem-solving.

Shopping Example

Suppose three items cost $5 each, and you also pay a $4 delivery fee.

The expression is:

3 × 5 + 4

First:

3 × 5 = 15

Then:

15 + 4 = 19

The total is $19.

Measurement Example

Suppose a rectangle has a length of 8 meters and a width of 3 meters.

Its area is:

8 × 3 = 24 square meters

The calculation is simple, but more complicated formulas may require several operations.

BODMAS or PEMDAS: Common Confusions


Most confusion comes from misunderstanding the priority of operations rather than from the acronyms themselves.

Does PEMDAS Mean Multiply Before Divide?

No.

Multiplication and division have equal priority. Work from left to right.

Does BODMAS Mean Divide Before Multiply?

No.

Division and multiplication are also equal in BODMAS. The left-to-right rule applies.

Does Addition Come Before Subtraction?

No.

Addition and subtraction have equal priority, so solve them from left to right.

Are BODMAS and PEMDAS Different Rules?

No.

They are different mnemonic systems that describe the same general order of operations.
