Introduction to Scientific Notation: Writing and Converting Very Small Numbers

This video tutorial teaches how to write very small numbers using scientific notation. It covers the basics of scientific notation, including the use of powers of ten, and explains how to multiply and divide by these powers. The lesson also explores the concept of positive and negative exponents, demonstrating how they relate to repeated multiplication and division. Practical examples are provided to illustrate the conversion of numbers to scientific notation and vice versa. By the end of the lesson, viewers will understand how to handle both positive and negative exponents in scientific notation.
