Understanding Scientific Notation Concepts

The video tutorial explains how to multiply numbers in scientific notation. It begins by introducing the concept of scientific notation multiplication, emphasizing the importance of keeping the numbers in scientific notation. The tutorial then details the process of multiplying the coefficients and adding the exponents. Finally, it addresses the need to adjust the result to ensure the coefficient is between 1 and 10, explaining how to move the decimal point accordingly.

What is the first step when multiplying numbers in scientific notation?
