Order of Magnitude
"Value is measured in orders of magnitude. This allows for easier comparison, because 1036 and 1042 are easier to compare than 1,000,000,000,000,000,000,000,000,000,000,000,000 and 100,000,000,000,000,000,000,000,000,000,000,000,000,000. With Orders of Magnitude, you don't have to painstakingly count the zeroes; you can use exponent rules to calculate 1042 divided by 1036 as 1042-36, which simplifies to 106, meaning one value is 1 million times the other."
