Scientific Notation and Significant Figures

Mr. Post provides an extra help session focusing on scientific notation and significant figures. The session includes an overview of scientific notation, explanations of positive and negative exponents, and multiple examples of converting numbers to scientific notation. The importance of significant figures in scientific notation is also discussed, with practical examples to reinforce learning. The session concludes with a summary and an invitation for further help if needed.
