No.
No
Yes.
No. For example, (81 / 9) / 3 = 9 / 3 = 3 81 / (9 / 3) = 81 / 3 = 27
Yes. Multiplication of integers, of rational numbers, of real numbers, and even of complex numbers, is both commutative and associative.
No it is not an associative property.
No.
No
Well, honey, the statement that division of a whole number is associative is as false as claiming you can wear a swimsuit in a blizzard. Just take the numbers 10, 5, and 2 for example. (10 ÷ 5) ÷ 2 is not the same as 10 ÷ (5 ÷ 2). So, there you have it - a sassy counterexample for you!
Yes.
No. For example, (81 / 9) / 3 = 9 / 3 = 3 81 / (9 / 3) = 81 / 3 = 27
Yes. Multiplication of integers, of rational numbers, of real numbers, and even of complex numbers, is both commutative and associative.
No, and the word is subtraction, not substraction!
Yes. Multiplication of any real numbers has the associative property: (a x b) x c = a x (b x c)
No!
The set of whole numbers is not closed under division (by non-zero whole numbers).
The whole numbers are not closed under division! The statement is false since, for example, 2/3 is not a whole number.
