What are Greek Numerals?

Greek numerals are a numeric system used by the ancient Greeks, where the Greek alphabet's letters represent numbers. The structure of the Greek numeral system is somewhat similar to Roman numerals, but it uses different letters and rules.

Basic Rules of Greek Numerals

The Greek numeral system consists of 27 letters, with 24 letters used to represent numbers like 1 to 9, 10 to 90, 100 to 900, and so on. Larger numbers are represented by combinations of letters. Similar to Roman numerals, Greek numerals follow addition and subtraction rules: a larger letter before a smaller one indicates addition, while a smaller letter before a larger one indicates subtraction.

How to Represent Larger Numbers?

In the Greek numeral system, larger numbers can be represented by using a reversed accent (͵) and symbols (Μ). The reversed accent multiplies the number following it by 1000; Μ represents "ten thousand," and ΜΜ represents "one hundred million" (i.e., one M multiplies the number by 10,000). For example:
