The term W(X + YZ) can be converted into POS form by applying which law? The commutative law of addition and multiplication specifies the following: Determine the binary values of the variable for which the following default POS expression is 0. In mathematics, commutative law is one of the two laws relating to the numerical operations of addition and multiplication, symbolically given as a + b = b + a and ab = ba. It follows from these laws that any finite sum or product is unchanged by rearranging its terms or factors. While commutativity is valid for many systems, such as real or complex numbers, there are other systems, such as the n × n matrix system or the quaternion system, in which the commutativity of multiplication is invalid. The scalar multiplication of two vectors (to obtain the so-called point product) is commutative (i.e. a·b = b·a), but vector multiplication (to obtain the cross product) is not (i.e. a × b = −b × a). The commutative law does not necessarily apply to the multiplication of conditionally convergent series. See also Associations Act; Distributive law. Which of the following examples expresses the commutative law of multiplication? 1.
