Understanding Scientific Notation Concepts

The video tutorial by Mr. J explains how to write large numbers in scientific notation. It begins with an introduction to the concept, highlighting its usefulness in simplifying large and small numbers. The tutorial then provides four examples, each demonstrating the step-by-step process of converting different large numbers into scientific notation. The video concludes with a brief mention of the next topic, which will cover writing small numbers in scientific notation.

What is the main purpose of using scientific notation?
