Numbers that are larger than one million are usually either represented using scientific notation, or by words. [1] There are two main ways of using words to write large numbers. The American way or "Short form" for naming large numbers is different from the European way or "Long form" of naming large numbers.

The naming procedure for large numbers is based on taking the number n occurring in 10 3n+3 (short scale) or 10 6n (long scale) and concatenating Latin roots for its units, tens, and hundreds place, together with the suffix -illion. In this way, numbers up to 10 3·999+3 = 10 3000 (short scale) or 10 6·999 = 10 5994 (long scale) may be named.

Trillion is a 1 with 12 zeros after it, and it looks like this: 1,000,000,000,000. The next named number after trillion is quadrillion, which is a 1 with 15 zeros after it: 1,000,000,000,000,000. There are, of course, many numbers between trillion and quadrillion, but it isn't until quadrillion that that number value actually gets a new name.

Most people know 1,000 is called a thousand, and 1,000,000 is called a million, but what is a quadrillion? Or a sextillion? I have compiled this list for that purpose. There is not a standard naming scheme for numbers over a million, and different countries call numbers different things.

In mathematics, 0.999... (also written as 0.9, 0..9, or 0. (9)) is a repeating decimal that is an alternative way of writing the number 1. Following the standard rules for representing numbers in decimal notation, its value is the smallest number greater than or equal to every number in the sequence 0.9, 0.99, 0.999, ....

Large numbers are numbers above one million that are usually represented either with the use of an exponent such as 10 9 or by terms such as billion or thousand millions that frequently differ from system to system.

The greater than or less than comparison is used to determine the relationship between two numbers. If one number is of a greater magnitude than another number, then it is said to be greater than that number. For example, if you have two numbers, 3 and 5, the comparison of these two numbers will tell you that 5 is greater than 3.

2004年2月5日 · In the English-speaking world two different systems have been used to name numbers larger than a million, one associated with the United States and the other with Great Britain. In the U.S., one billion is a thousand millions; in the U.K. it is, or was, a million millions.

2016年11月9日 · When is .999... less than 1? We examine alternative interpretations of the symbol described as nought, point, nine recurring. Is "an infinite number of 9s" merely a figure of speech? How are such alternative interpretations related to infinite cardinalities? How are they expressed in Lightstone's "semicolon" notation?
