The video tutorial demonstrates how to use calculators to solve algebraic problems, including identifying zeros, roots, and rational numbers. It covers techniques like guess and check, matching equations to tables, and understanding domain and range. The tutorial also explains growth and decay in functions and how to evaluate functions at specific points.
