Simplification is a crucial topic when it comes to competitive exams * IBPS PO, SBI PO, SBI Clerk, IBPS Clerk, RRB Assistant, RRB Scale 1, LIC Assistant, LIC AAO* and other banking and insurance exams. Understanding this topic well is important because you will typically encounter around 5 easy simplification questions in the prelims of these exams. For those who want to take their simplification skills to the next level,

Simplification is concept that involves making complex mathematical equations simpler and easier to compute or understand. Simplification typically requires the application of mathematical operations, rules, and principles to reduce a given mathematical expression to its simplest form. This topic basically tests your calculation skills. If you're confident in your ability to perform ** quick calculations** and understand the basic rules for solving simplification questions, you can easily score five marks in just a matter of seconds. It's a low-hanging fruit in terms of scoring.

In competitive exams, two common types of simplification questions are encountered:

** 1. Finding the Missing Number:** In this type of simplification question, you will be presented with an equation in which one or more numbers or variables are missing. The task is to fill in the blank(s) with the appropriate numbers or values to make the equation true. These blanks can be on either the left-hand side or the right-hand side of the equation. You need to apply mathematical operations and principles to deduce the missing values and complete the equation.

** For Example: **540 -? + 75 = 6 × 50 + 315

2.

** For example**: 456 + 187/3 – 259x2 =?

Mastering BODMAS/BIDMAS

BODMAS provides a systematic framework for solving simplification questions, ensuring that operations are carried out in a logical and consistent order. Mastering BODMAS is not just about following a rule but also about understanding the order of operations, which is a fundamental skill in solving simplification questions.

** Breaking Down BODMAS: **BODMAS is an abbreviation that represents a specific order of operations to be followed when solving mathematical expressions:

The first step is to evaluate any expressions within brackets. If there are multiple sets of brackets, start with the innermost and work outward.**Brackets (B):**Next, calculate any values with indices or powers. This includes operations involving square roots, exponents, and other mathematical functions.**Orders (O):**Perform division operations from left to right in the expression.**Division (D):**Carry out multiplication operations from left to right in the expression.**Multiplication (M):**Add any remaining values together, proceeding from left to right.**Addition (A):**

** Subtraction (S):** Finally, subtract any remaining values from left to right.

**The BODMAS Process: **To illustrate how BODMAS works, let’s consider an example:

**Expression: 4 + (5 × 3) – 2/2**

**Using BODMAS:**

1. Brackets: Solve the expression inside the brackets first: 5 × 3 = 15.

2. Orders: There are no exponents or powers in this case, so we move on.

3. Division and Multiplication: Now, perform division: 2/2 = 1

4. Addition and Subtraction: Finally, carry out addition and subtraction from left to right: 4 + 15 - 1 = 18.## Effective Tips for Solving Simplification

4. Addition and Subtraction: Finally, carry out addition and subtraction from left to right: 4 + 15 - 1 = 18.

Addition and Subtraction: Finally, carry out addition and subtraction from left to right: 4 + 15 - 1 = 18.

**Practice Example:**

**689 × 6156 ÷ 18% of 684 = 28 × 250 ÷ 8 + ? + 4300**

**Solution: **

689 × 6156 ÷ 18% of 684 = 28 × 250 ÷ 8 + ? + 4300

** Applying BODMAS, first remove percentage**,

or, 689 × 6156 ÷ 123.12 = 28 × 31.25 + ? + 4300

or, 689 × 50 = 875 + ? + 4300

∴ ? = 34450 – 5175 = 29275

Simplification is a crucial component of competitive exams, particularly in fields like banking and insurance. It requires quick and accurate mathematical calculations. Here are some valuable tips to enhance your simplification skills and perform better in these exams:

- Memorize
to increase your mental calculation speed.**tables up to 20** - Memorizing
and**squares till 30**will also expedite your calculations.**cubes till 20** - Learn common
and**percentage to fraction**conversions. For example, knowing that 50% is equivalent to 1/2 and 25% is equivalent to 1/4 can simplify calculations significantly.**fraction to percentage** - Dedicate time to
