1.1: Introduction to Decimal Calculations
In \(1784\), Thomas Jefferson proposed a decimal currency system for the United States based on the Spanish dollar, with coins for \(10\) dollars, \(1\) dollar, 1⁄10 dollar, and 1⁄100 dollar. One argument he advanced in favor of this system was that the 1⁄100-dollar coin would be similar in value to existing copper coins. The initial currency of the United States was minted in \(1792\) with the dollar being equal to \(100\) cents. Working with decimals is essential when calculating or analyzing most currency data, whether it be from historical or modern times!
