Intergers

Hallo gaiss, kembali lagi di blog Mathematics yang ga pernah bosan membahas materi seputar matematika. Karena matematika itu mudahh hehe

Kali ini saya akan membahas tentang Integers, semoga bermanfaat and enjoyy

Integers is a number that can be written without a fractional component.

For example 21, 4, 0 and -2048 are integers. While 5 1/2 and Ö2 are not. Z often used to denote the set of all integers.

Example of notation : {…,-4,-3,-2,-1,0,1,2,3,4,…}

Integers divided to :

1. Chopped numbers

Example : {0,1,2,3,4,5,…}

2. Natural number

Example : {1,2,3,4,5,6,..}

Natural number divided to :

          a)    Odd number

          Example : {1,3,5,7,9,11…}

          b)   Even number

         Example : {2,4,6,8,10,12,…}

          c)   Prime number

         Example : {2,3,5,7,11,13,…}

          d)   Composite number

         Example : {4,6,8,9,10,14,…}

     

  Comparing the integers

Symbol :

1.   > (more than).

Example : 3 > 1

Because the position three more right from one.

2.  < (less than).

Example : -2 < 2

Because the position -2 more left from two.
