Understanding Algebraic Terms and Expressions

The video tutorial introduces key algebraic terms such as constants, variables, coefficients, terms, expressions, and equations. A constant is a standalone number, while a variable or pronumeral represents an unknown value. A coefficient is a number paired with a variable. Terms can be numbers, variables, or combinations of both. An expression is a combination of terms, and an equation is an expression with an equal sign. The tutorial provides a foundational understanding of these concepts, essential for algebraic problem-solving.
