The commutative property for addition is a + b = b + a
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 = 60and (3x4)x5 = 12x5 = 60It 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 = BxAMatrix 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.
it can be used to write a multiplication sentence by flipping the numbers around
no just write zero. or maybe like an example 2x0=0
Because multiplying is the inverse of dividing
7r = r + r + r + r + r + r + r or r7
Mainly the commutative property. But the fact that 30*8*7 is unambiguous and you do not need to write (30*8)*7 or 30*(8*7) is due to the associative property.

The commutative property states that given any two numbers, x and y,x + y = y + xThe property applies to all real numbers and complex numbers as well.2.3 + 4.5 = 6.8 = 4.5 + 2.3
The sum of b and 8 would be written b+8 or 8+b(commutative property of addition)
The associative property of multiplication states that for any three numbers a, b and c, (a * b) * c = a * (b * c) and so we can write either as a * b * c without ambiguity. The associative property of multiplication means that you can change the grouping of the expression and still have the same product.
