Exploring Exponents and Base Numbers

This video tutorial covers the basics of exponents and base numbers, explaining how exponents indicate the number of times a base is used as a factor. It discusses reading and writing exponents, using them in geometry for area and volume calculations, and applying the order of operations. The tutorial also introduces negative exponents and previews future lessons on division.
