What does billions mean in math?

Answer 1

In math, "billions" refers to the number 1,000,000,000, which is equivalent to 10^9 in exponential notation. It is often used to describe large quantities, such as population figures or financial amounts. In the short scale system, commonly used in the United States and most English-speaking countries, one billion is one thousand million. Conversely, in some countries using the long scale, a billion can refer to a million million (10^12), though this usage is less common today.
