The numbers 1, 2, 3, 4.... Are called as natural numbers, their set is shown by N. Hence N = {1, 2, 3, 4, 5....}


The numbers 0, 1, 2, 3, 4...... Are known as whole numbers, their set is presented by W. therefore W = {0, 1, 2, 3, 4....}


The numbers. ...- 3, -2, -1, 0, 1, 2, 3....are known as integers and their set is shown by I & Z

Set of positive integers shown by I+ and consists of {1, 2, 3...}, also called as set of natural numbers.

Set of negative integers shown by I- and consists of {...- 3, - 2, - 1}

Set of non-negative integers is {0,1,2, 3...} also called as set of whole numbers

Set of non-positive integers is {...- 3, - 2, - 1, 0}
