How many properties are there in whole numbers in maths?

Whole numbers have several key properties, including closure, commutativity, associativity, and the existence of an identity element. Closure means that the sum or product of any two whole numbers is also a whole number. Commutativity indicates that the order of addition or multiplication does not affect the result, while associativity means that the grouping of numbers does not change their sum or product. Lastly, the identity element for addition is 0, and for multiplication, it is 1.
