Sexagesimal System
Sexagesimal, also known as base 60, is a numeral system with sixty as its base. It originated with the ancient Sumerians in the 3rd millennium BC, was passed down to the ancient Babylonians, and is still used—in a modified form—for measuring time, angles, and geographic coordinates. The number 60, a superior highly composite number, has twelve divisors, namely 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, and 60, of which 2, 3, and 5 are prime numbers. With so many factors, many fractions involving sexagesimal numbers are simplified. For example, one hour can be divided evenly into sections of 30 minutes, 20 minutes, 15 minutes, 12 minutes, 10 minutes, 6 minutes, 5 minutes, 4 minutes, 3 minutes, 2 minutes, and 1 minute. 60 is the smallest number that is divisible by every number from 1 to 6; that is, it is the lowest common multiple of 1, 2, 3, 4, 5, and 6. ''In this article, all sexagesimal digits are represented as decimal numbers, except where otherwise noted. For example, the la ...

Numeral System
A numeral system is a writing system for expressing numbers; that is, a mathematical notation for representing numbers of a given set, using digits or other symbols in a consistent manner. The same sequence of symbols may represent different numbers in different numeral systems. For example, "11" represents the number ''eleven'' in the decimal or base-10 numeral system (today, the most common system globally), the number ''three'' in the binary or base-2 numeral system (used in modern computers), and the number ''two'' in the unary numeral system (used in tallying scores). The number the numeral represents is called its ''value''. Additionally, not all number systems can represent the same set of numbers; for example, Roman, Greek, and Egyptian numerals don't have a representation of the number zero. Ideally, a numeral system will: *Represent a useful set of numbers (e.g. all integers, or rational numbers) *Give every number represented a unique representation (or a ...

Mina (unit)
The mina (; ; ; ; ; ; ) is an ancient Near Eastern unit of weight for silver or gold, equivalent to approximately , which was divided into 60 shekels. The mina, like the shekel, eventually also became a unit of currency. History Sumerian From earliest History of Sumer, Sumerian times, a mina was a unit of weight. At first, talents and shekels had not yet been introduced. By the time of Ur-Nammu (shortly before 2000 BCE), the mina had a value of Talent (weight), talent as well as 60 shekels. The weight of this mina is calculated at , or 570 grams of silver (18 troy ounces). Semitic languages The word mina comes from the ancient Semitic root / 'to count', Akkadian language, Akkadian , (), / (/), (), . It is mentioned in the Bible, where Solomon is reported to have made 300 shields, each with 3 "mina" of gold (), or later after the Edict of Cyrus II of Persia the people are reported to have donated 5000 minas of silver for the reconstruction of Solomon's Temple in Jerusalem ...
