Everything you need to know about BODMAS Rules
Oct 13, 2025 Admin
Mathematics is often called the language of logic. But just like any language, it has rules — and one of the most important ones is the BODMAS rule.
If you’ve ever been confused about whether to add or multiply first, you’re not alone. The BODMAS rule in maths helps students solve mathematical expressions step by step in the right order. Mastering it means fewer mistakes, more confidence, and higher math scores!
What Does BODMAS Stand For?
The BODMAS formula explains the correct order in which to perform operations:
Letter |
Meaning |
Operation Type |
Example |
B |
Brackets |
( ), { }, [ ] |
(6 + 2) × 3 |
O |
Orders |
Powers, roots, exponents |
3², √16 |
D |
Division |
÷ |
12 ÷ 3 |
M |
Multiplication |
× |
5 × 2 |
A |
Addition |
+ |
7 + 3 |
S |
Subtraction |
– |
10 – 4 |
👉 The rule ensures that no matter how complex a sum looks, everyone solves it the same way.
Why Is the BODMAS Rule Important?
Imagine you have this question:
6 + 2 × 3 = ?
If you add first: (6 + 2) × 3 = 24
If you multiply first: 6 + (2 × 3) = 12
The correct answer is 12, because multiplication comes before addition as per the BODMAS rule.
Without BODMAS, math would be chaos — every student might end up with a different answer for the same question!
Step-by-Step Process Using the BODMAS Formula
Follow this order every time:
- B – Brackets: Solve everything inside brackets first.
- O – Orders: Handle powers, roots, or exponents.
- D – Division: Work from left to right.
- M – Multiplication: Continue left to right.
- A – Addition: Next, add numbers.
- S – Subtraction: Finally, subtract.
📘 Tip: Division and multiplication share the same priority — solve whichever comes first from left to right. The same goes for addition and subtraction.
BODMAS Rule Examples
Here are some simple BODMAS rule examples to understand how it works:
Example |
Step-by-Step Solution |
Final Answer |
8 + 4 × 2 |
4 × 2 = 8 → 8 + 8 = 16 |
✅ 16 |
(6 + 2) × 3 |
(6 + 2) = 8 → 8 × 3 = 24 |
✅ 24 |
12 ÷ (3 × 2) + 4 |
3 × 2 = 6 → 12 ÷ 6 = 2 → 2 + 4 = 6 |
✅ 6 |
18 ÷ 3 × 2 + 5 |
18 ÷ 3 = 6 → 6 × 2 = 12 → 12 + 5 = 17 |
✅ 17 |
BODMAS vs PEMDAS
In some countries (like the USA), the same concept is called PEMDAS —
P for Parentheses, E for Exponents, M/D for Multiplication/Division, and A/S for Addition/Subtraction.

👉 Both rules are identical in logic — they just use different names.
Common Mistakes Students Make
- ❌ Ignoring brackets and starting with multiplication.
- ❌ Solving all multiplication before division, instead of left to right.
- ❌ Forgetting powers or square roots before basic operations.
- ❌ Doing addition before subtraction when subtraction comes first.
✔️ Always remember: BODMAS is about sequence — not speed!
Practice BODMAS Questions
Try these on your own:
- (5 + 3) × 2 – 4 ÷ 2 = ?
- 15 – 3 × (2 + 1) = ?
- 9 + 6 ÷ 3 × 2 – 1 = ?
- (8 + 4) ÷ 2 × 3 = ?
- 4 + 9 × (6 – 4) ÷ 2 = ?
You can check your answers using an online BODMAS calculator — it’s a handy tool for quick verification.
Real-Life Use of the BODMAS Rule
BODMAS isn’t just for textbooks — it’s everywhere in real life:
- 💰 While calculating discounts and taxes.
- 📊 While creating data formulas in Excel or Google Sheets.
- 🧮 While coding mathematical programs.
- 🧠 In logical reasoning and aptitude tests.
That’s why understanding BODMAS rule in maths helps beyond the classroom.
Benefits of Learning BODMAS Early
- Builds clear mathematical thinking.
- Reduces silly mistakes in exams.
- Improves logical and problem-solving skills.
- Makes higher-level math easier.
- Boosts confidence in handling complex questions.

❓ Frequently Asked Questions (FAQs) on BODMAS
1) What is the BODMAS rule in maths?
The BODMAS rule defines the correct order to solve mathematical operations: Brackets → Orders → Division → Multiplication → Addition → Subtraction.
2) What is the BODMAS formula?
The BODMAS formula helps solve expressions step by step, ensuring accuracy. It prioritizes brackets and powers before other operations.
3) How can I solve BODMAS questions easily?
Write each step separately, follow the BODMAS order, and double-check your answer using a BODMAS calculator online.
4) Is BODMAS and PEMDAS the same?
Yes. BODMAS (used in India/UK) and PEMDAS (used in the USA) both represent the order of operations rule in mathematics.
5) Why is BODMAS important for students?
It ensures consistency, accuracy, and logical problem-solving — skills that help in exams, real-life calculations, and even coding.
6) What comes first - multiplication or division?
Both have the same priority. You solve from left to right as they appear in the expression.
Final Thoughts
Learning the BODMAS rule is like learning traffic rules for numbers — once you know the order, there’s no confusion!
So remember:
👉 Brackets → Orders → Division → Multiplication → Addition → Subtraction
Keep practicing BODMAS rule examples, solve daily BODMAS questions, and soon, solving complex expressions will feel like second nature.
