BODMAS Questions

Mathematics can often seem overwhelming, especially when dealing with complex expressions that involve multiple operations. The BODMAS rule is an essential concept that helps break down these challenges by explaining the correct order of operations in mathematical expressions. It is widely used to simplify equations and reduce calculation time, making it crucial to master this concept from the outset. Whether you are a student learning math or preparing for competitive exams like SAT, GMAT, or GRE, having a solid grasp of BODMAS is critical to solving problems accurately and efficiently. This blog provides a comprehensive guide to BODMAS questions, offering valuable practice to help you build a solid foundation in this essential mathematical skill.

What is BODMAS?

BODMAS is an acronym used in mathematics to remember the correct order of operations while solving expressions. It stands for:

  • B: Brackets
  • O: Order of Indices (powers, roots, and likewise.)
  • D: Division
  • M: Multiplication
  • A: Addition
  • S: Subtraction

Following the BODMAS rule ensures that every equation is solved in the right sequence, giving accurate results. Without it, solving expressions randomly may lead to mistakes.

The golden rule is:

B ➝ O ➝ D ➝ M ➝ A ➝ S

Start with brackets, then indices, followed by division, multiplication, addition, and finally subtraction. This sequence helps

Step-by-Step Explanation

Now, let’s break down each step of BODMAS to understand how it works in solving mathematical expressions.

LettersSteps
B (Brackets)Solve everything inside brackets first
O (Orders/Indices)Work out powers, squares, cubes, or roots
D (Division)Divide the numbers given in the expression
M (Multiplication)Multiply the numbers next
A (Addition)Add the numbers that follow
S (Subtraction)Subtract the remaining numbers at the end

Example:

Solve 8 + (6 ÷ 2) × 3

Step 1: Brackets first

Inside the bracket, we have 6 ÷ 2.

6 ÷ 2 = 3

Now the expression becomes:

8 + 3 × 3

Step 2: Multiplication/Division (from left to right)

Next, multiply 3 × 3 = 9

Now the expression becomes:

8 + 9

Step 3: Addition/Subtraction

8 + 9 = 17

Understanding the Components of BODMAS

BODMAS helps us determine the correct order of operations in any mathematical expression. Let’s break down each component:

1. Brackets

Brackets indicate the operations that must be done first. There are three types:

  • Parentheses ( ): Used for basic grouping of numbers or operations.

    Example: (3 + 5) × 2.
  • Square brackets [ ]: Used when parentheses are already present.

    Example: [2 × (3 + 4)].
  • Curly braces { }: Rarely used but helpful for multiple layers of nesting.

    Example: {2 + [3 × (4 + 1)]}.

2. Orders (Exponents)

Orders refer to powers and roots. This includes:

  • Exponents: Squaring a number

    (Example, 22=42^2 = 422=4) or cubing a number
    (Example, 33=273^3 = 2733=27).
  • Roots: Square roots or cube roots (Example: 9=3\sqrt{9} = 39​=3).

3. Division and Multiplication

Division (÷) and multiplication (×) have equal priority. Solve them from left to right as they appear.

Example: 8 ÷ 2 × 3 → First divide 8 ÷ 2 = 4, then multiply 4 × 3 = 12.

4. Addition and Subtraction

Addition (+) and subtraction (−) also share the same priority. Solve them from left to right after completing brackets, exponents, division, and multiplication.

Example: 10 − 4 + 2 → First subtract 10 − 4 = 6, then add 6 + 2 = 8.

  • Always solve the innermost brackets first before moving to outer brackets.
  • Perform multiplication and division before addition and subtraction in any expression.
  • Handle nested brackets step by step, simplifying one bracket at a time.
  • Calculate powers and roots immediately after resolving brackets.
  • Simplify fractions properly before performing any further operations.
  • Keep decimal precision throughout all calculations until the final result.
  • Pay close attention to negative numbers and their impact on operations.

FAQs

What is the BODMAS rule, for example?

Answer: The BODMAS rule suggests that while solving a complex equation comprising various operations, we must follow BODMAS in order to further solve the problem.
For example: (2 + 3 ) x 4
We will first solve the brackets as per the BODMAS rule, 5 x 3 and then multiply. So, the answer is 20!

What is the rule of BODMAS Question?

Answer: BODMAS rule stands for Brackets, Of, Division, Multiplication, Addition and Subtraction. It states the order of operations according to which we can solve a complex problem.

How do you simplify Bar Questions?

Answer: The bar questions denote that the operations under the bar must be given preference followed by BODMAS while solving a particular equation.

Does BODMAS apply when there are no brackets?

Answer: Yes, BODMAS is applied even to places where there are no brackets. In such a case we just work on the other operations.

What does BODMAS stand for in mathematics?

Answer: BODMAS is an acronym that stands for Brackets, Orders, Division, Multiplication, Addition, and Subtraction. It is a set of rules used to determine the order in which operations should be performed in a mathematical expression. According to BODMAS, calculations are performed in the following order:
Brackets
Orders (exponents or powers)
Division
Multiplication
Addition
Subtraction

Ques. Why are BODMAS Questions important in mathematics?

Answer: BODMAS question are crucial because it provides a clear and standardized method for solving mathematical expressions. Without following BODMAS, different people might interpret and solve the same problem in different ways, leading to inconsistent results. It ensures that calculations are carried out logically, minimizing errors and confusion.

How does BODMAS apply to negative numbers?

Answer: When negative numbers are involved, BODMAS still applies, but extra caution is needed while performing operations like multiplication or division. For example, in an expression like -2 × (4 + 3), first, solve inside the brackets: 4 + 3 = 7, then multiply by -2: -2 × 7 = -14.

What is the difference between BODMAS and PEMDAS?

Answer: BODMAS and PEMDAS are essentially the same rules, but the acronym differs. PEMDAS stands for Parentheses, Exponents, Multiplication and Division, Addition and Subtraction, while BODMAS stands for Brackets, Orders, Division and Multiplication, Addition and Subtraction. The order of operations is the same; only the terms are named differently.

How do you solve a BODMAS Question with multiple brackets?

Answer: If there are multiple brackets in BODMAS question, start by solving the innermost bracket first and then work outward. For example, for the expression (3 + (2 × 4)) ÷ 2, first calculate 2 × 4 = 8, then add it to 3 to get 3 + 8 = 11, and finally, divide by 2 to get 11 ÷ 2 = 5.5.

What are some common mistakes when solving BODMAS Question?

Answer: Common mistakes include:
– Ignoring the order of operations (e.g., performing addition before multiplication).
– Misinterpreting brackets, especially when nested.
– Incorrectly applying negative signs with multiplication or division.
– Skipping steps like dividing before multiplication when they appear in the same expression.

What happens if you don’t follow BODMAS rule?

Answer: If you don’t follow the BODMAS rule, the results of the expression may be incorrect. For example, changing the order of operations in a problem can lead to vastly different answers. This makes BODMAS critical for obtaining the correct result in mathematical calculations.

How does BODMAS affect algebraic expressions?

Answer: In algebraic expressions, BODMAS is used to prioritize operations in the same way as numerical expressions. For instance, when simplifying or solving algebraic equations like 3x + (2x – 4) ÷ 2, the operations inside brackets must be resolved first, followed by division, and then addition/subtraction.

What role do exponents play in BODMAS Questions?

Answer: Exponents (or orders) are an essential part of BODMAS, following brackets. For instance, in the expression 2 + 3 × 2², you first calculate the exponent (2² = 4), then perform the multiplication (3 × 4 = 12), and finally, add 2 (2 + 12 = 14).

Can a BODMAS expression contain multiple operations?

Answer: Yes, a BODMAS expression can contain several operations. It can include multiple brackets, exponents, divisions, multiplications, additions, and subtractions. For example, in the expression (5 + 3) × (4² ÷ 2) – 6, multiple operations are used, and the order of execution must follow the BODMAS rule to get the correct answer.
