Write the following properties for whole numbers analyze anf If you have questions  , socializate next class! Properties of the whole numbers ·          Whole numbers are the natural number that starts with zero. The property of whole number includes Closure property of whole numbers Commutative property (addition and multiplication) of whole number Associative property(addition and multiplication) of whole number Multiplicative identity of whole number Zero property of addition of whole number Zero property of multiplication of whole number 1. Closure and Commutative property: Closure property: The closure property says that the addition of the two whole numbers will   give the whole number Let v and s are whole numbers Here (v+s) is a whole numbers For example: 1)     23 +23 = 46. 2)     11 +15= 26. 2. Commutative property (addition and multiplicatio...
