Prealgebra is the combination of elements from Arithmetic and Algebra I. Arithmetic topics are treated as review items while Algebra I topics are introduced more deliberately than in Algebra I. Prealgebra is typically taken in 6th or 7th grade and is often used as a developmental course at the college level.
