Many students find bodmas questions for class 7 confusing because they are not sure which operation to solve first. When addition, subtraction, multiplication, and division appear together, even small mistakes in order can change the final answer. This confusion often leads to lost marks, even when calculations are otherwise correct.
In Class 7, BODMAS is an important part of maths exams and daily practice. It is used in simplification, fractions, decimals, and mixed operations. Understanding the correct order of operations helps students solve questions with confidence.
This page is designed to explain BODMAS in a clear, step-by-step way. Students can learn calmly, and parents can easily guide homework without confusion.
What Is the BODMAS Rule? (Concept Clarity for Class 7)
Meaning of BODMAS Rule in Simple Words
The bodmas rule for class 7 helps students decide the correct order to solve maths questions that have more than one operation. It tells us which part of a question should be solved first and which should come later.
B stands for Brackets. Any part of the question inside brackets is always solved first. This helps keep calculations organised and clear.
O stands for Orders, which means powers or roots if they appear in a question. These are solved after brackets.
D and M stand for Division and Multiplication. These are done next, but always from left to right, not based on which comes first in the word.
A and S stand for Addition and Subtraction. These are done at the end, again from left to right. Following this order avoids confusion and mistakes.
Why Order of Operations Is Important in Class 7 Maths
In Class 7 maths, the same question can give different answers if the order of operations is not followed correctly. This is why students sometimes feel confused even after doing the calculations carefully. The mistake usually happens when operations are solved in the wrong order.
In school exams, teachers do not check only the final answer. They also check the steps used to reach that answer. If the order is wrong, marks can be lost even when the final number looks correct. Understanding the correct order helps students solve questions confidently and write proper steps in exams.
How to Apply BODMAS Step by Step (Before Solving Questions)
Correct Order to Solve Any BODMAS Question
To avoid mistakes, students should always follow step by step bodmas solutions instead of jumping to calculations. The first step is to carefully look at the full question and identify all the operations involved. Rushing without reading the question properly often leads to errors.
Always start by solving the part inside brackets, as this has the highest priority. After brackets, solve orders such as powers or roots if they are present. Next, move to division and multiplication. These two are done from left to right, not based on which one appears first in the word BODMAS.
Finally, complete addition and subtraction, again from left to right. Following this fixed sequence helps students stay organised and write clear steps in exams.
Where Students Usually Get Confused
Many students get confused between division and multiplication. They think division must always be done before multiplication, which is not correct. In BODMAS, both are solved from left to right, depending on their position in the question.
Another common mistake happens with addition and subtraction. Students often try to finish subtraction at the end, instead of following the left-to-right order. This leads to wrong answers even when calculations are done carefully.
Some students also skip brackets too early or solve outside the bracket first. Brackets should always be completed before moving to other operations.

Exam-Focused Tips for BODMAS Questions (Class 7)
How BODMAS Questions Are Asked in Exams
In Class 7 school exams, BODMAS questions usually appear as short answer or simplification questions. They may carry 1, 2, or sometimes 3 marks. These questions test whether students follow the correct order of operations, not just calculation speed. Even small BODMAS-based sums are used to check concept clarity. Parents should know that these questions are common across CBSE, ICSE, and State Board papers and are an important part of internal tests and final exams.
How to Write Steps for Full Marks
Writing clear steps is very important to score full marks in BODMAS questions. Students should write one operation per step and avoid jumping directly to the final answer. This helps teachers understand the method and award marks even if a small mistake happens later. Parents can reassure children that neat working and correct order matter more than speed. Practising step-wise writing builds exam confidence.
FAQs on BODMAS Questions for Class 7
Q. Why is BODMAS important for Class 7 students?
BODMAS helps students solve maths questions in the correct order. In Class 7, many sums have mixed operations. Following BODMAS avoids confusion, improves accuracy, and helps students write proper steps in exams.
Q. Do BODMAS questions come in Class 7 exams?
Yes, BODMAS-based questions are common in Class 7 exams. They appear in simplification, integers, fractions, and decimals. These questions test concept clarity and correct working, not just the final answer.
