Denary is an adjective that typically refers to something related to the number ten or based on the number ten. It stems from the Latin word "denarius," which means ten. In mathematics, denary describes a numbering system based on ten, commonly known as the decimal system. It is the most widespread numerical system used by humans today, consisting of ten digits (0, 1, 2, 3, 4, 5, 6, 7, 8, 9) and a place value system, where each digit's position is ten times greater than the one before it.
Denary can also be used to describe the numbering system's operations of addition, subtraction, multiplication, and division applied to numbers represented in the decimal system. For example, denary addition involves adding two or more decimal numbers together using the place value system, where each digit's value is based on its position relative to the decimal point.
Furthermore, denary can be used to describe a monetary system based on the number ten. In ancient Rome, a denarius was a silver coin that was equal to ten "asses," thus reflecting the use of the number ten in the Roman currency system.
Overall, denary refers to the number ten and its various applications in mathematics, numerical systems, and currency systems.
