Scientific Notation and Decimal Operations

Professor Perez introduces scientific notation, explaining its purpose and representation. The video is divided into two parts: understanding scientific notation and converting numbers into this format. Examples are provided to illustrate numbers that meet the criteria for scientific notation in a beginning algebra context. The video also explores patterns in decimal movement when using scientific notation and applies these concepts to various examples, demonstrating how to convert numbers into proper scientific notation.
