Quizplus · Accepted Answer

A variable represents one or more unknown values and can take on different values in an equation or problem. Constants are known values that do not change, and an equation is a mathematical expression stating that two things are equal to each other. "Known" is not the best choice as it does not refer to the concept of representing unknown values.
