[1] Elementary algebra, also known as high school algebra or college algebra, [2] encompasses the basic concepts of algebra. It is often contrasted with arithmetic: arithmetic deals with specified numbers, [3] whilst algebra introduces variables (quantities without fixed values). [4]
Basic topics in elementary mathematics include polygons, circles, perimeter and areas. A polygon is a shape that is bounded by a finite chain of straight line segments closing in a loop to form a closed chain or circuit .
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.
In mathematics, a basic algebraic operation is any one of the common operations of elementary algebra, which include addition, subtraction, multiplication, division, raising to a whole number power, and taking roots (fractional power). [1] These operations may be performed on numbers, in which case they are often called arithmetic operations.
Formally, this is described in algebraic notation like this: (19 + 1) + (15 − 1) = x, but even a young student might use this technique without calling it algebra. The PSSM recommends that all students complete pre-algebra coursework by the end of eighth grade and take an algebra class during high school. [10]
The average math score for eighth grade students was unchanged from 2022, while reading scores fell 2 points at both grade levels. One-third of eighth grade students scored below “basic” in reading, more than ever in the history of the assessment. Students are considered below basic if they are missing fundamental skills.
Algebra includes the study of algebraic structures, which are sets and operations defined on these sets satisfying certain axioms. The field of algebra is further divided according to which structure is studied; for instance, group theory concerns an algebraic structure called group.

In math, fourth graders were 41% at or above proficient, up from 35% two years ago, and 77% were at or above basic, up from 75%. Eighth graders were 31% at or above proficient, up from 25% two ...
