The video tutorial reviews key algebraic vocabulary, including variables, constants, coefficients, and terms. Variables are unknowns in expressions, constants are numbers without variables, coefficients are numbers multiplied by variables, and terms are parts of equations separated by addition or subtraction symbols. The tutorial emphasizes the importance of understanding these concepts for solving algebraic problems.
