An alphabetic numeral system employs the letters of a script in the specific order of the alphabet in order to express numerals. In Greek, letters are assigned to respective numbers in the following sets: 1 through 9, 10 through 90, 100 through 900, and so on. Decimal places are represented by a single symbol.
v. t. e. Number systems have progressed from the use of fingersand tally marks, perhaps more than 40,000 years ago, to the use of sets of glyphsable to represent any conceivable number efficiently. The earliest known unambiguous notations for numbers emerged in Mesopotamiaabout 5000 or 6000 years ago. Prehistory.

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 ...
The system of ancient Egyptian numerals was used in Ancient Egypt from around 3000 BC [1] until the early first millennium AD. It was a system of numeration based on multiples of ten, often rounded off to the higher power, written in hieroglyphs. The Egyptians had no concept of a positional notation such as the decimal system. [2]
1742 — Christian Goldbach conjectures that every even number greater than two can be expressed as the sum of two primes, now known as Goldbach's conjecture. 1770 — Joseph Louis Lagrange proves the four-square theorem, that every positive integer is the sum of four squares of integers. In the same year, Edward Waring conjectures Waring's ...
Alphabetical order was first used in the 1st millennium BCE by Northwest Semitic scribes using the abjad system. [1] However, a range of other methods of classifying and ordering material, including geographical, chronological, hierarchical and by category, were preferred over alphabetical order for centuries.
