The Associative property of multiplication states that the product of a set of three numbers is always the same no matter which operation is carried out first.
For example Ax(BxC) = (AxB)xC and so either can be written as AxBxC.
ie 3x(4x5) = 3x20 = 60
and (3x4)x5 = 12x5 = 60
It is important not to confuse this with the commutative (or Abelian) property which states that the order of the numbers does not matter. ie AxB = BxA
Matrix multiplication, for example, is associative but NOT commutative.
(a * b) * c = a * (b * c)
As a result, we can write a * b * c without ambiguity.

There is only one associative property for multiplication: there is not a separate "regular" version.
No, you cannot have subtraction in the associative property of multiplication because the associative property of multiplication is about multiplication. More to the point, if you're asking whether subtraction is associative, the answer is still no. (2 - 3) - 4 does not equal 2 - (3 - 4)
They are the Associative Property of Multiplication, the Commutative Property of Multiplication, and the Zero Property of Multiplication.
its like a fatality
The associative property. It works separately for addition and for multiplication.
