Numbers were first used for counting, and the roman numerals, which were based on finger counting, were used in Britain up to the seventeenth century. They were replaced by Hindu-Arabic symbols similar to the familiar 1, 2, 3, 4, 5, 6, 7, 8, 9, 0, used today, and these are called digits after the Latin word for ‘finger’. In most countries the denary system of counting in tens is used, but other systems are considered in Chapter 6, including binary arithmetic.
