Scientific Notation and Unit Conversions

John from Smart Edition Academy introduces a video on the chemistry section of the TEAS 7, focusing on scientific notation. The video explains how to convert large and small numbers into scientific notation, detailing the components of scientific notation: coefficient, base ten, and exponent. It also covers unit conversion between metric and imperial systems, providing practical examples. The video aims to help students struggling with these topics and offers additional resources for further learning.
