This document discusses algebra basics, specifically terms and expressions. A term consists of a number or variable along with an optional sign. An expression is a collection of terms combined using addition or subtraction. Terms with the same variables can be combined by collecting like terms, where terms are rearranged and variables with the same symbols are added together.
