The meaning of Simplification is to resolve the complicated mathematics problem and providing the exact simplified answer.
The Simplification Questions are made by involving at least two numbers in an expression.
Here is an example which can help you to define a question based on Simplification asked in various competitive exams.
Illustration – 16+4÷2
If we solve the above-mentioned expression, then the final value that we get is 18.
To solve this expression, we have used the BODMAS formula which is the basic root of attempting any type of Simplification Questions.
If you don’t know, what is the BODMAS Formula and how to use it to simplify an expression then below we have provided the detailed information about it.
Scroll the page to know about BODMAS.
Suggested Reads -
An Acronym that is used to know the order to solve mathematical problems.
With the help of BODMAS, we get the correct sequence to resolve and find the correct value of a given expression.
The BODMAS acronym is for –
Brackets
Orders
Division
Multiplication
Addition
Subtraction
So, according to this acronym following are the steps to solve the Simplification Questions –
Brackets - Start solving the expression from the value inside the brackets, going from left to right. While solving the bracket you also need to apply the BODMAS Formula.
For an example –
5× (6+2) =?
Here firstly, we need to solve the values inside the bracket and after that multiply it by 5 to get the correct answer.
5×8 =?
So the correct answer is 40.
Orders – After solving the brackets, in the next step, you should evaluate exponents (power or a square root also known as orders).
Example –
4^{2}+9 =?
Here, you need to evaluate the square of 4 and then add 9 to it.
4×4+9=25
Division and Multiplication – After completing the above mentioned two steps, you have to perform the Division and Multiplication. Both ranks equally, so you should go from left to right to solve the expression.
Example –
7×5÷5+8 =?
While going from left to right, firstly multiply 7 by 5 and then the resultant should be divided by 5.
35÷5+8 =? Or 7+8 =?
So, the result that we get is 15.
Addition and Subtraction – The final step of Simplification is Addition or Subtraction. Also, these two ranks equally. Go from left to right to solve the expression.
Example –
7+4-1+5 =?
After going through left to right in the above-mentioned Simplification Question we get the following values –
11-1+5 or 10+5 or 15
So, the final answer after applying Addition and Subtractions is 15.
We hope that you are now pretty much aware of the BODMAS Formula that helps to solve the Simplification Questions easily.
As there are different types of brackets used in Simplification Questions, candidates might face problem to solve such type of questions.
Below we have clarified the way to eliminate the brackets while solving the Simplification Questions.
There are commonly three types of brackets used in Simplification Aptitude Questions. Candidates must know the sequence to eliminate these brackets in an expression.
From the table given below, you can check the different types of brackets and their order of elimination.
Type of Brackets |
Order to Eliminate Brackets |
( ) – Common Bracket |
First |
{ } – Curly Bracket |
Second |
[ ] – Rectangular Bracket |
Third |
To practice these methods, you can prefer the perfect example of Simplification Question that we have provided in this article.

Example – What would come in place of the question mark (?)
17 + 24 ÷ 12 × (16 ÷ 4) ^2 - 5 =?
Solution –
Step 1 – Eliminate Brackets
17 + 24 ÷ 12 × 4^{2} - 5
Step 2 – Exponents
17 + 24 ÷ 12 × 16 - 5
Step 3 – Division and Multiplication (Left to Right)
17 + 2 × 16 - 5 = 17 + 32 - 5
Step 4 – Addition and Subtraction (Left to Right)
49 - 5 = 44
After simplifying the expression by using BODMAS, the correct answer is 44.
There are some other important factors that should be considered while solving Simplification Problems.
