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:

  1. Classification problems
  2. Divisibility Test problems
  3. Division& Remainder Rules problems
  4. 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)
