Scientific Notation Concepts and Rules

The video tutorial explains how to multiply numbers in scientific notation, focusing on handling very small numbers with negative exponents. It covers the rules of scientific notation, including the requirement for the coefficient to be between 1 and 10 and the exponent to be an integer. The tutorial demonstrates how to perform operations like multiplication, emphasizing the importance of multiplying coefficients and adding exponents. An example calculation is provided to illustrate the process, showing how to adjust the decimal point to ensure the result is in proper scientific notation.
