The American number system is commonly referred to as the "base-10" or "decimal" system, which is a positional numeral system that uses ten digits (0-9) to represent numbers. It is the most widely used number system in the United States and many other countries for everyday counting and calculations. Additionally, the system incorporates concepts such as place value and the use of commas and periods for separating large numbers and decimal fractions, respectively.
