How do you say 100000000000000000000?

Answer 1

The number 100,000,000,000,000,000,000 is called one hundred quintillion in the short scale commonly used in the United States and modern English-speaking countries. In the long scale, which is used in some European countries, it would be referred to as one hundred trillion. The term "quintillion" comes from the Latin root "quinque," meaning five, indicating that it has five sets of three zeros following the initial one.
