Sometimes boxes or shapes are used to indicate unknown values. As such, number sentences are used to introduce students to notions of structure and elementary algebra prior to a more formal treatment of these concepts. A number sentence without unknowns is equivalent to a logical proposition expressed using the notation of arithmetic.
Precalculus is the exception to the rule, as it usually integrates algebra, trigonometry, and geometry topics. Statistics may be integrated into all the courses or presented as a separate course. New York State began using integrated math curricula in the 1980s, [4] but recently returned to a traditional curriculum.
Unlike abstract algebra, elementary algebra is not concerned with algebraic structures outside the realm of real and complex numbers. It is typically taught to secondary school students and at introductory college level in the United States, [5] and builds on their understanding of arithmetic. The use of variables to denote quantities allows ...

A typical sequence of secondary-school (grades 6 to 12) courses in mathematics reads: Pre-Algebra (7th or 8th grade), Algebra I, Geometry, Algebra II, Pre-calculus, and Calculus or Statistics. However, some students enroll in integrated programs [ 3 ] while many complete high school without passing Calculus or Statistics.
