BODMAS Questions

BODMAS stands for Bracket, Of, Division, Multiplication, Addition and Subtraction. The BODMAS is used to explain the order of operations of a mathematical expression. It is an essential mathematical concept used in an array of places where you need to solve complex equations. It helps in solving simplification questions and reduce calculation time in most cases. Therefore, it is mandatory to have a stronghold over this concept from the start. To all those who are trying their hands on various competitive exams or preparing this topic for the scholastic exams like SAT, GMAT or GRE, here is a blog with BODMAS questions to practice. 

What is BODMAS?

BODMAS stands for: 
B: Brackets
O: Order of Indices 
D: Division 
M: Multiplication 
A: Addition 
S: Subtraction 

Now, let us understand the order in which it is used in mathematics- 

B ➝ O ➝ D ➝ M ➝ A ➝ S 

Starting from ‘B’ and moving towards the right of the word will give you correct and quick answers for those complex equations. Refer to the table below for a better understanding of this concept.

How to Solve BODMAS Questions?

The BODMAS rules simplify a mathematical equation by breaking it down. Let’s solve a BODMAS question to understand its rules.

Example: 4(10+15÷5×4-2×2)

Solve the Brackets:
Here, you must calculate the inside bracket first.
4(10+15÷5×4-2×2)
Within the Bracket, solve the division section first
4(10+15÷5x4-2×2)
Next, within the bracket itself, solve the multiplication
4(10+3×4–2×2)
Next, within the bracket, solve the addition
4(10+12-4)
At last, within the bracket, solve the subtraction:
4(22-4)
Once the bracket is solved, pick up the number from the outside and solve the ‘Of’ section by multiplication:
=4×18
Answer=72

So,the result of 4(10+15÷5×4-2×2)= 72

You can solve even the most complicated mathematical questions using this BODMAS rule of Brackets of Division, Multiplication, Addition and Subtraction.

Here is the order of operations rule in BODMAS:

BODMAS Rules

As per the BODMAS rule, the first thing you need to do while solving a question is the simplification of brackets. But do you really know how to simplify brackets? Don’t worry, let’s discover ways of removing brackets and expanding an expression with the help of an example: 

Suppose we have an equation x (y + z), to open brackets and expand the terms, we will use the Distributive Property which states that a (b + c) = ab + bc. Therefore in the given equation will become : x (y + z) =xy + xz. 

We hope the simplification of brackets is clear to you know. Let us look at some complex examples for a better understanding. 

Example 1: Expand and simplify 9 (5 + 3) 

Solution
In question 9 (5 + 3) let us use the Distributive Property [a (b + c) = ab + bc]
9 (5 + 3) = 9 × 5 + 9 × 3
= 45 + 27 
= 72

Therefore, the answer is 72.

Example 2: Expand and simplify 11 (2y+ 3)

Solution: 
We will again use the Distributive Property [a (b + c) = ab + bc] to proceed with the question 11 (2y + 3). The equation will become: 
11 (2y + 3) = 11 × 2y + 11 × 3
= 22y + 33 

Therefore, the answer is 22y + 33!

Solved BODMAS Questions and Answers

BODMAS is an important topic of Maths which is a part of class 8 Maths, class 10 Maths and class 9 ICSE Maths. Thus to explain this topic better, we have solved a few BODMAS questions for you, have a look:

Solved BODMAS Question 1

Solved BODMAS Question 2

Find the value of ‘a’ using the concept of BODMAS. 
42 ÷ 2 + a × 3 − 22 = 8

Solution:
42 ÷ 2 + a × 3 − 22 = 8
Using BODMAS, we will first work on the division 
21 + a × 3 – 22 = 8
Next, we will do the rearrangement of terms, followed by subtraction
a 3 – 22 + 21 = 8
a × 3 – 1 = 8
Taking -1 to the other side 
a × 3 = 8 + 1 
a × 3 = 9 
a = 9/3 
a = 3

The value of a is 3!

Solved BODMAS Question 3

Find the value of 3+3 of 3÷3 of 3×3

Solution:
To understand the question better, let us add brackets to this problem
Therefore, 3 + 3 of 3 ÷ 3 of 3 × 3 will become 3 + (3 of 3) ÷ 3 of 3 × 3
Using BODMAS, we will first work on brackets and of
3 + 9 ÷ 3 of 3 × 3
3 + 3 of 3 × 3
3 + (3 of 3) × 3
3 + 9 × 3
As per the BODMAS rule, we will solve multiplication first
3 + 27
= 30

Therefore, the answer is 30!

Solved BODMAS Question 4

In equation 9 + 7 × 1= 5 − 3 which pair of signs should we interchange in order to make it correct? The available options are + with ×, + with –, × with – or + with –.

Solution:
For the given 4 option, the only × with – is making the equation correct. Let us understand verify it by replacing these signs in the above mentioned BODMAS question.

Original Equation: 9 + 7 × 1= 5 − 3
New Equation: 9 + 7 − 1 = 5 × 3

Using the BODMAS rule, we would first wok on the multiplication
9 + 7 − 1 = 15
16 − 1 = 15
15 = 15

Hence verified that × with – is the correct choice!

Solved BODMAS Question 6

Solved BODMAS Question 7

Find the value of x in the following equation 6162 + x + 3330 = 2545

Solution:
6162 + x + 3330 = 2545
We will first rearrange the equation
6162 + 3330 + x = 2545

Using the BODMAS rule, we will first do the addition
9492 + x = 2545

Shifting 9492 to the other side of the equation
x = 2455 – 9492
= – 6947

Therefore, the answer is – 6947.

Solved BODMAS Question 8

Find the value of 6 ÷ 2 + 7 × 4

Solution:
As per the BODMAS rule, we will start solving the equation by division:
6 ÷ 2 + 7 × 4
3 + 7 x 4

Next operation that falls next as per the BODMAS rule is Multiplication
3 + 7 x 4
3 + 28
= 31

Therefore, the answer is 31.

Solved BODMAS Question 10

Simplify [72 – 12 ÷ by 3 – 2 ]+ ( 18 – 6) ÷ 4

Solution:
To simplify the given BODMAS question, we can start by operating the brackets. As brackets further involve division and subtraction, we will division
[72 – 12 ÷ by 3 – 2] + ( 18 – 6) ÷ 4
[72 – 4 – 2] + ( 18 – 6) ÷ 4
66 + 12 ÷ 4

Now we will first work on the division first
66 + 12 ÷ 4
66 + 3
= 69

Therefore, the simplified value is 69!

Find the value of 40 – [20 – {14 – (16 – 6 x 4 – 2)}]

Solution:
As per the BODMAS rule, we will start solving the question by working on the brackets. Within the brackets, we will start with Multiplication followed by subtraction
40 – [20 – {14 – (16 – 6 x 4 – 2)}]
40 – [20 – {14 – (16 – 24 – 2)}]

Property of integers suggests, – and – become +, therefore
40 – [20 – {14 – (16 – 26)}]
40 – [20 – {14 – (-10)}]

Again using – and – become +
40 – [20 – {14 + 10}]
40 – [20 – 24]
40 – [-4]
40 + 4
= 44

Therefore, the answer is 44!
