Properties of whole numbers

Properties of whole numbers:



Whole Numbers:While solving problems we usually come across questions like what do we mean by whole numbers,how can we identify whole numbers.Below is the explanation for these type of frequently asked questions

Meaning of whole numbers:

The set of whole numbers is the set of natural numbers along with zero. so W = the set of whole numbers = 0,1,2,3,............

so Zero is the least number of the set of Whole numbers.

As the whole numbers is an infinite set we cant determine the highest number of this set.

The set of Whole numbers is a subset of Rational numbers.
Let us now learn about the Properties of whole numbers
Properties of Whole numbers:

t is advisable to use a number line inorder to understand the properties of whole numbers.

1. Number 3 < 5 and the number 3 is to the left of the number 5.Hence of an two numbers on a number line, the smaller number is to the left of the greater number.So too,of any two numbers on a number line the number to the left of the other number, is the smaller of the two.

2. There is no whole number to the left of zero on the number line.So zero is the smaller number than each of the numbers to its right on the number line.That means 0 is the smallest or least of the whole numbers.

3. A whole number which is greater than a given whole number by 1 is said to be a successive whole number. 1 is the successive whole number to 0.Every whole number has one successor.

4. There is no whole number left to zero.hence 0 is not a successive whole number of any whole.
