How to Solve Mixed Operation Problems Using BODMAS (PEMDAS) in Class 4
FAQs on Class 4 Maths Add, Subtract, Multiply, Divide with Parenthesis
1. What is the order of operations for Class 4?
The order of operations for Class 4 is a set of rules that tells you which calculation to perform first in a sum with multiple operations, commonly remembered by the acronym BODMAS or PEMDAS. It ensures everyone gets the same correct answer for the same problem.
The sequence to follow is:
- Brackets (or Parentheses) - Solve what's inside the brackets first.
- Orders (or Exponents) - Usually introduced after Class 4.
- Division and Multiplication - Solve these from left to right as they appear.
- Addition and Subtraction - Solve these last, from left to right as they appear.
2. How do you solve mixed operation sums with brackets?
To solve mixed operation sums with brackets, you must always calculate the part inside the brackets (parenthesis) first, before performing any other operations like multiplication, division, addition, or subtraction. This is the first and most important step in the BODMAS rule.
Here are the steps:
- Step 1: Identify the expression inside the brackets.
- Step 2: Solve the calculation within the brackets. For example, in (5 + 3) × 2, you solve 5 + 3 to get 8.
- Step 3: Replace the entire bracketed part with its single answer. The sum becomes 8 × 2.
- Step 4: Continue solving the rest of the sum using the remaining BODMAS rules.
3. What are some examples of BODMAS problems for kids?
BODMAS problems for kids in Class 4 typically involve multiple basic operations and brackets, requiring them to follow a specific order to find the correct answer. This worksheet provides practice with five numbers.
Here are some examples:
- Simple Example: 10 + (5 × 2) – 3 = 10 + 10 - 3 = 17
- With Division: (15 - 5) ÷ 2 + 1 = 10 ÷ 2 + 1 = 5 + 1 = 6
- Five Numbers Example: 20 ÷ (2 + 3) × 4 - 1 = 20 ÷ 5 × 4 - 1 = 4 × 4 - 1 = 16 - 1 = 15

8. What is the BODMAS rule in maths for Class 4?
The BODMAS rule is an acronym that helps Class 4 students remember the correct order for solving math problems with multiple operations. It is essential for getting accurate answers.
The acronym stands for:
- B - Brackets (solve this first)
- O - Orders (powers or roots)
- D - Division
- M - Multiplication
- A - Addition
- S - Subtraction
9. Why is it important to practice mixed operations with parenthesis in Grade 4?
Practising mixed operations with parenthesis is crucial in Grade 4 as it builds the foundational skills needed for more advanced mathematics, such as algebra. It is a key topic in the CBSE and other school syllabi.
The main reasons are:
- It teaches mathematical reasoning and the importance of following logical rules.
- It enhances number sense and the ability to handle multi-step calculations.
- Mastering BODMAS prevents common calculation errors in higher classes.
