        Chapter-2- Whole Numbers


        Lesson Note: 2.3


        Subtopics:
                     Properties of whole numbers
                     Closure property
                     Commutative property
                     Distributive property
                     Zero property of whole numbers


              Properties of whole numbers:  The properties of whole numbers are based on arithmetic
               operations such as addition, subtraction, division and multiplication on numbers.

              Closure Property :

               Let us say 5 and 10 are two whole numbers, then 5 × 10 = 50 is also a whole number or   5 + 10 = 15

        is also a whole number.

               Sum of any two whole numbers the result is always a whole numbers.

               Product of any two whole numbers the result is always a whole numbers.

               
                     we conclude that whole numbers are closed under addition and also

               under multiplication.


               Are the whole numbers closed under division?

               Let us find : 8 ÷ 2 = 4 (4 is a whole number).

               Let us find: 8 ÷ 16

                              8
                               =
                             16

                             1         1
                               =              (    is a fraction which is not a whole number).
