Understanding terms and expressions In algebra, letters are used when numbers are not known. Algebraic terms , such as \(2s\) or \(8y\), leave the multiplication signs out.

Examples of Algebraic Expressions: x + 3, 4xy + 7, 2y – 5, etc. Algebraic Expressions are formed using variables (letters) and constants.
