What Is BODMAS? A Simple Guide for Beginners (India)

If maths sums with lots of numbers and symbols have ever felt confusing, BODMAS is the friendly rule that brings order to the chaos. It is one of the first “big ideas” Indian students learn in middle school, and it stays useful for the rest of your life — in exams, in shops, and even in spreadsheets at work. This simple guide explains what BODMAS is in plain language, with everyday Indian examples and no complicated jargon.

Key takeaway: BODMAS is like a queue at a railway counter — there is an order, and everyone follows it. Skip the queue and you get the wrong result.

What Does BODMAS Mean?

BODMAS is a short, easy-to-remember word made from the first letters of six maths steps. Each letter tells you which job to do and when. Think of it as a to-do list that always runs top to bottom.

The order of the letters is the order of the work. You never jump ahead. And here is the one thing beginners must remember: division and multiplication are best friends of equal importance, and so are addition and subtraction. When two equal jobs appear, you simply do the one on the left first.

Why Do We Need BODMAS?

Imagine you and a friend both solve 2 + 3 × 4. Without a rule, one of you might add first (2 + 3 = 5, then 5 × 4 = 20) and the other might multiply first (3 × 4 = 12, then 2 + 12 = 14). Two different answers for the same sum — that is a problem. BODMAS solves it by saying multiplication comes before addition, so the correct answer is 14. This is why every teacher, exam board, calculator, and billing machine in India follows the same rule. It keeps maths fair and predictable for everyone.

A Simple Way to Remember It

Many Indian students remember BODMAS with a small sentence or by picturing the four “levels” of a building you climb down: you enter through the Brackets on the top floor, pass the Orders, then the Division–Multiplication floor, and finally reach the ground floor of Addition–Subtraction. You can only go one floor at a time, in order.

Everyday Indian Examples

Example 1: Buying vegetables

You buy 2 kg of tomatoes at ₹30 and 3 kg of onions at ₹20. The cost is 2 × 30 + 3 × 20. Multiply first: 60 + 60 = ₹120. BODMAS tells you to multiply before adding, which matches how a shopkeeper totals a bill.

Example 2: Sharing a pizza bill

Four friends order food for ₹800 and use a ₹200 coupon, then split what remains: ( 800 − 200 ) ÷ 4. Bracket first: 800 − 200 = 600, then 600 ÷ 4 = ₹150 each. The brackets make sure you subtract before dividing.

Example 3: A small power

Solve 5 + 2² × 3. Orders first: 2² = 4. Then multiply: 4 × 3 = 12. Then add: 5 + 12 = 17.

Benefits of Learning BODMAS Early

Learning BODMAS well in middle school makes almost everything that follows easier. It builds the habit of working step by step, which is exactly the skill algebra will demand a year or two later. It boosts confidence in exams because you stop guessing which operation to do first. It also helps in daily life — checking a restaurant bill, working out a discount during a sale, or splitting costs with friends all use the same order. And because calculators and phone apps follow BODMAS too, understanding it means technology behaves the way you expect rather than surprising you.

Challenges Beginners Face

The most common struggle is believing that you must always divide before you multiply, or add before you subtract, just because D comes before M and A comes before S in the word. That is not true — those pairs are equal and go left to right. Another challenge is nested brackets, where one bracket sits inside another; beginners sometimes start from the outside instead of the inside. Powers and the word “of” can also confuse newcomers until they learn these belong to the Orders step. None of these are hard once explained, but they cause most early mistakes.

Common Mistakes to Avoid

1. Adding before multiplying. Always handle × and ÷ before + and −.
2. Forcing division before multiplication. They are equal; go left to right.
3. Ignoring brackets. Whatever is inside brackets must be solved first, from the innermost pair.
4. Forgetting powers. A small ² or ³ is an Orders job and comes before division.
5. Doing it all in your head. Beginners should write each step to avoid slips.
6. Rushing WhatsApp puzzles. Those “trick” sums are just BODMAS done too quickly.

Best Practices for Beginners

1. Say the word aloud — B, O, D, M, A, S — as a checklist before you start.
2. Write one line per step so you can see your progress and catch errors.
3. Circle the part you are solving to stay focused on one operation at a time.
4. Use a free BODMAS calculator to check your answer after you finish.
5. Practise with real prices from shopping bills to make the rule feel useful.
6. Ask “which is stronger?” — multiplication beats addition, powers beat multiplication — to reason it out.

BODMAS, DMAS and the “Of” Word

Younger Indian students often first meet a shorter version called DMAS — just Division, Multiplication, Addition, and Subtraction — before brackets and orders are added to make the full BODMAS. If you learned DMAS in primary school, BODMAS is simply the grown-up version with two extra jobs on top. The letter “O” also quietly includes the little word “of”, which in maths means multiply. So “half of 60” is the same as ½ × 60 = 30, and it is solved at the Orders stage, before any plain addition or subtraction. Knowing this stops the classic mix-up where students treat “of” as an ordinary word instead of a maths instruction.

Example 4: Using “of” in a sum

Solve ½ of 60 + 10. First the “of”: ½ of 60 = 30. Then add: 30 + 10 = 40. If you added 60 + 10 first by mistake, you would get a completely different, wrong answer.

A quick self-test

Try these three on your own, then check with a calculator: (a) 10 − 2 × 3, (b) ( 10 − 2 ) × 3, and (c) 4² ÷ 2. Notice how the brackets in (b) completely change the answer compared with (a) — that is the power of the very first step in BODMAS.

The answers are (a) 10 − 6 = 4, (b) 8 × 3 = 24, and (c) 16 ÷ 2 = 8. If you got all three right, you already understand the heart of BODMAS: look for brackets and powers first, then work steadily down through the remaining operations from left to right. With a little daily practice on real sums like shopping bills and pocket-money calculations, the order becomes second nature and you stop having to think about it consciously at all.

Conclusion

BODMAS is simply the agreed order for solving a maths sum: brackets, orders, division and multiplication, then addition and subtraction. It exists so that everyone reaches the same correct answer, whether they are a Class 6 student in Jaipur or a cashier in Kochi. Learn the order, remember that division/multiplication and addition/subtraction are equal pairs solved left to right, write your steps down, and check with a calculator. Do that, and maths sums stop being confusing and start feeling like a simple, predictable routine.

FAQs

What is BODMAS in easy words?
It is the order for solving a sum: brackets first, then powers, then division and multiplication, then addition and subtraction. It makes sure everyone gets the same answer.

Which comes first, multiplication or addition?
Multiplication always comes first because it has higher priority than addition in BODMAS.

At what class is BODMAS taught in India?
It is usually introduced around Class 6 in the NCERT and CBSE syllabus and revised in later classes.

Is BODMAS the same as PEMDAS?
Yes. PEMDAS is the American name for the same order of operations, and both give identical answers.

Do I always divide before I multiply?
No. Division and multiplication are equally important, so you do whichever comes first from the left.
