INTRODUCTION OF INTEGERS

__INTEGERS__

**As we know that, the
collection of numbers …………, -7, -6, - 5, -4, -3, -2, -1, 0, 1, 2, 3, 4, 5, 6,
7,..………. are called integers whereas …………, -7, -6, - 5, -4, -3, -2,…… are
called negative integers and 1, 2, 3, 4, 5, 6, 7,..………. are called positive
integers. The integers zero ‘0’ is neither positive nor negative integers. The
set of integers is denoted by I or Z and N ****⊆**** I or Z
and W ****⊆**** I or Z.**

**To be remembered – a) All positive integers are more than
Zero and all negative integers are less than zero.**

**b) All and every positive integers are greater than all and
every negative integers**

**c) Given two positive integers, the one with the bigger
absolute value is greater, and given two negative integers the one with the
smaller absolute value is greater.**

**d) The absolute value of an integer is the whole number
obtained by disregarding its sign, the absolute value of an integers ‘b’ is
denoted by (+b) **
