Multiplication and Scientific Notation

This tutorial covers the multiplication of numbers in scientific notation. It begins with an introduction to the concept, followed by three examples demonstrating multiplication with positive, mixed, and negative exponents. The tutorial explains the rules for multiplying the base numbers and adding the exponents, providing step-by-step guidance for each example. The video concludes with a brief mention of the next topic, division in scientific notation.
