Which law of real numbers is demonstrated by c(x+y=y+xc)?
Answer and explanation
Correct answer: Commutative law
In this equation, interchanging x and y does not change the sum: x+y=y+x. Therefore, it represents the commutative law of addition. The distributive law involves multiplying over a sum, such as x(y+z)=xy+xz. In an exam, if changing the order of terms leaves the result unchanged, identify the commutative law.
