EXPLANATION
Addition:
If we add two or more whole numbers, the result will be also a whole number.
Hence, they exhibit the closure property.
Subtraction:
If we subtracti two or more whole numbers, the result will not necessarily be a whole number. For example, subtraction 5-10 give us -5 --> Not a whole number. [NOT CLOSURE PROPERTY]
Division:
The division of two whole numbers could not necessarily be a whole number, as for instance, 6/12 = 1/2 [NOT CLOSURE PROPERTY]
