**Simplification problems tricks **Simplification topic is one of the most important part of Aptitude section of all competitive exam. Today I am sharing my knowledge with you.Today i am sharing all the techniques and *simplifications problems tricks* to solve Simplification Problems in easily in a short time its to take to Fifteen to thirty seconds.

First of You Know all basics like solving in a proper way.

## Simplification problems tricks:

Rules of Simplification:

VBODMAS:

V => Vinculum

B => Remove Brackets – in the order ( ) , { }, [ ]

O => Of

D => Division

M => Multiplication

A => Addition

S => Subtraction

**Simplifications is divided into Five Parts:**

Simplifications is divided into Five Parts:

1)Number System

2)HCF & LCM

3)Square & Cube

4)Fractions & Decimals

5)Surds & Indices

We discuss each topic below go through on this first of all we discuss Number system.Number system is divided into Some parts these are:

- Classification problems
- Divisibility Test problems
- Division& Remainder Rules problems
- Sum Rules problems

**1)Classification:**

**1)Natural Numbers:**

Natural Numbers are like all counting Numbers ( 1,2,3,4,5….∞)

**2)Whole Numbers:**

Whole numbers nothing but some natural numbers like ( 0,1,2,3,4,5…∞)

**3)Integers:**

Integers are all whole Numbers both +ve and -ve Numbers (∞……-4,-3,-2,-1,0,1,2,3,4,5….∞)

**4)Even and odd Numbers:**

Even Numbers is nothing But all whole numbers is divisible by 2 ex:(0,2,4,6,8,10,12…..∞)

Odd Numbers is nothing but which numbers is not divisible by 2 ex:(1,3,5,7,9,11,13,15,17,19….∞)

**5)Prime numbers:**

Prime numbers can be Positive or Negative Numbers except 1,if the number is not divisible by any number except the number itself.

**6)Composite Numbers:**Composite Numbers natural numbers which are not prime numbers.

**7)Co-Prime:**Co-Prime numbers can be defined as the Two natural number a and b are said to be co-prime if their HCF is 1.

### 2)Divisibility Test for Simplification problems tricks:

Divisibility is nothing but some numbers are divided into another number.

**1).Divisibility by 2:**If any number end with 0,2,4,6,8 that all numbers are divisible by 2.

Example:24,528,624,788

**2).Divisibility by 3:**Sum of its all digits is divisible by 3.

Example:12,102,546.

**3).Divisibility by 4:**Last two digits is divisible by 4.

Example:24,528,624,788,7648.

**4).Divisibility by 5:**If any number end with 0 or 5 ,that all numbers are divisible by 5.

Example:520,600,5000,5555.

**5).Divisibility by 6**:If any number divides by both 2 and 3 ,that all numbers are divisible by 6.

Example: 4536

6).**Divisibility by 8**:Sum of last three digits of a number is divisible by 8.

Example:846848.

7).**Divisibility by 10**:If any number end with 0 is divisible by 10.

Example;1220,1450,2450,8400.

8).**Divisibility by 11:**(Sum of its digit in odd places-Sum of its digits in even places)= 0 or multiple of 11 or exactly divisible by 11.

Example:

Consider the number 49798848

(Sum of its digits at odd places)-(Sum of its digits at even places)(8+8+9+9)-(4+8+7+4)
