Did you know that the Internet was created in the 1950s as part of the United States Department of Defense? Then in the 1980s, private industries became involved in Internet usage and the rest is history! The Internet has grown very fast. In 1995, there were 18,000 websites. By 2006, the number of websites had grown to 100,000,000. Since then, the number of Internet websites has doubled, tripled, and quadrupled. The number 100,000,000 is quite large, so if we want to predict how large the Internet may grow, we would need to multiply very large numbers. To perform these types of operations on a number this size, we can use scientific notation.
