The term "dollar" refers to a unit of currency used in numerous countries, each of which typically divides the dollar into 100 cents. This decimal-based system simplifies transactions and calculations, allowing for easier monetary exchanges. The dollar's structure can be traced back to historical coins known as the "Thaler," which served as a precursor to modern currency systems.

In modern times, the dollar remains a keystone in understanding international finance, as it is often used as a benchmark for global trade.
