What this chapter is about
Algebra is the language of mathematics. While arithmetic deals with specific numbers, algebra deals with general patterns using variables — symbols that stand for unknown or changing quantities. An algebraic expression is a combination of variables, constants, and arithmetic operations. Expressions like $4x + 5$, $3x^2 - 2y$, and $xy + 7$ are the basic building blocks of all of algebra, equation-solving, and higher mathematics.
