Positive Integers

Definition
The numbers 1, 2, 3, 4, 5,.... and so on..... all are called Positive Integers.
We can also say that all natural numbers are Positive Integers also.
For example = 90, 7, 2653, 309372 all are positive integers.

Note = Zero is neither a positive nor a negative integers.

Following examples further explain Positive Integers :-

Example 1 = From the given series of integers, pick Positive Integers:
Given series of integers = 1, 16, -768, 90, -56, -1, 897, -11, -900
Answer = Positive Integers = 1, 16, 90, 897

Example 2 = From the given series of integers, pick Positive Integers:
Given series of integers = 23, -89, -90, 23234, 90, 342, 100
Answer = Positive Integers = 23, 23234, 90, 342, 100

Example 3 = From the given series of integers, pick Positive Integers:
Given series of integers = -901, -99, 832, -4, 6, 456, -22, 28
Answer = Positive Integers = 832, 6, 456, 28

Example 4 = From the given series of integers, pick Positive Integers:
Given series of integers = -20, 65, 342, -654, 450, 332, -10, -45, 87
Answer = Positive Integers = 65, 342, 450, 332, 87
