As an intermediate stage after arithmetic, prealgebra helps students pass specific conceptual barriers. Students are introduced to the idea that an equals sign, rather than just being the answer to a question as in basic arithmetic, means that two sides are equivalent and can be manipulated together. They also learn how numbers, variables, and words can be used in the same ways.[3]
