BODMAS Questions for Class 7 with Answers – Practice Problems

BODMAS Rule Questions for Class 7

The BODMAS rule, crucial in math, helps solve arithmetic expressions correctly. It means Brackets, Order (powers and roots), Division, Multiplication, Addition, and Subtraction. It guides the order of operations in an expression, ensuring consistent and correct solutions.

Understanding BODMAS is important for Class 7 students to tackle complex math problems efficiently. First, solve expressions inside brackets, then handle powers or roots. Next, do division and multiplication from left to right. Finally, do addition and subtraction, also from left to right.

What is BODMAS?

BODMAS is an acronym used in mathematics to remind students of the correct order to perform operations in complex calculations. BODMAS full form is:

B: Brackets (solve expressions inside parentheses, square brackets, curly braces, etc.)
O: Order (solve powers and roots)
D: Division
M: Multiplication
A: Addition
S: Subtraction

The BODMAS rule is crucial because it defines the sequence in which these mathematical operations should be carried out to ensure that everyone arrives at the same answer when solving the same arithmetic expression. It helps prevent confusion and errors in calculations, providing a clear, systematic approach to handling multiple operations.

Tips to Remember BODMAS Rule for Class 7

Here are some tips to help remember and effectively apply the BODMAS rule:

• Understand the Acronym: Memorize what BODMAS stands for—Brackets, Orders (powers and roots), Division and Multiplication, Addition and Subtraction. Remembering this order is crucial as it dictates the sequence in which parts of a mathematical expression should be solved.
• Practice with Brackets: Start by practicing problems that involve different types of brackets like parentheses ( ), square brackets [ ], and curly braces { }. This helps in understanding how to prioritize operations within various types of brackets.
• Master Orders: Ensure you’re comfortable with calculating powers and roots, as these are often where mistakes happen. Use flashcards or apps to drill powers and roots to gain fluency.
• Division and Multiplication: Recognize that division and multiplication have the same priority and are solved from left to right. Practice exercises with mixed division and multiplication to build confidence.
• Sequential Processing: Always work operations from left to right, especially within the same priority level. For example, in expressions involving both addition and subtraction, solve them in the order they appear from left to right.
• Use Mnemonics: Create a catchy phrase or story using the BODMAS acronym to make it more memorable. For instance, "Big Elephants Destroy Mice And Snails" can be used to represent Brackets, Exponents (Orders), Division, Multiplication, Addition, and Subtraction.
• Apply Real-World Problems: Solve real-world problems that require the use of the BODMAS rule. This application helps solidify understanding and shows the practical importance of the rule.
• Error Checking: After solving an expression, revisit each step to ensure that the BODMAS rule was correctly applied. This habit can prevent and correct mistakes.
  Interactive Learning Tools: Utilize online quizzes, games, and interactive tools designed to teach the BODMAS rule. These tools make learning fun and engaging, which can enhance memory and understanding.
• Group Study Sessions: Collaborate with peers in study groups to solve BODMAS problems together. Explaining steps to others and hearing how peers solve problems can reinforce learning and uncover common mistakes.

By following these tips, Class 7 students can gain a strong grasp of the BODMAS rule, leading to greater confidence and accuracy in solving mathematical expressions.

Why do some people get different answers for the same BODMAS question?

There are three main reasons:

• Implicit/explicit multiplication (e.g. of or not symbolically).
• The expression was unclearly written, which made it subject to different interpretations.
• It is wrongly believed that Division is always higher precedence over Multiplication (or Addition over Subtraction). If the expression is ambiguous, convention is left‐to‐right for equal operations.

Example: 20 ÷ 5 × 2

Wrong way (if you think division is higher than multiplication): 

Correct (left to right)
Step 1: 20 ÷ 5 = 4
Step 2: 4 × 2 = 8
Answer: 8

Wrong grouping (incorrect)
Step 1: 5 × 2 = 10 <-- grouping 5 and 2 first (not left-to-right)
Step 2: 20 ÷ 10 = 2
Answer: 2 (this is incorrect under standard rules)
