1. Perhaps you have heard before people say “zillion,” “gazillion,” “prillion,” and "Mega-Million" for large numbers. These terms are not actual names for very big numbers. You may have noticed that they are not included in the list above. People use these names vaguely to just refer to numbers that are very big and unknown.
2. It will take you a long time to count very big numbers.
For example, 1 year has 31,536,000 seconds.
1 quadrillion = 1,000,000,000,000,000
1,000,000,000,000,000 / 31,536,000 = 31,709,791.9838 years
What does this mean? If it takes you 1 second to say each number, it will take you more 31 million years to count from 1 all the way to 1 quadrillion. This is interesting since 1 quadrillion is still very small compared to the numbers that are towards the bottom of the list above.
