6. What is wrong with this property? (associative) 2+(34) = (2+3) 4

This property is not associative. It is Distributive.

This property is not associative. it is commutative.

There are mixed signs

Associative must be division or subtraction

7. What is wrong with this property? (commutative) 2-3 = 3-2

This property is not commutative. it is associative.

This property is not commutative. it is identity for subtraction.

There is nothing wrong with this property.

Commutative is not for subtraction or division.

8. What is wrong with this property? (zero) 8/0 = 0

There is no division in the zero property

The problem is "undetermined"

There is no such thing as the zero property

The answer of the problem is 8

9. What is wrong with this property? (distributive) 2(35) = (23) * (3*5)

This is associative. Not distributive.

Distributive is only over subtraction or addition.

Distributive is only over division or subtraction

This is commutative. not distributive

10. What is wrong with the following property? (zero over addition) 2+0 = 2

There is nothing wrong with the problem.

Zero property is only over subtraction.

There is no such thing as zero over addition.

This problem is distributive
