What is rearrangement property ?
Rearrangement Property of Addition: The addends in an addition expression may be arranged and grouped in any order. This is a combination of the associative and commutative axioms.
e.g. x + y + z = x + (y + z) = (x + y) + z = z + (y + x) = y + (z + x)
Rearrangement Property of Multiplication: The factors in a multiplication expression may be arranged and grouped in any order. This is a combination of the associative and commutative axioms.
e.g. xyz = x(yz) = z(yx) = y(zx)
