What was the ancient Greek number system?
Greek numerals are a system of representing numbers using letters of the Greek alphabet. They are also known by the names Milesian numerals, Alexandrian numerals, or alphabetic numerals. The acrophonic system was replaced by a new alphabetic system, sometimes called the Ionic numeral system, from the 4th century BC.
What are the symbols for multiplication and division?
Multiplication, using the x symbol, can show the same idea as repeated addition (of equal amounts), using the + symbol. The symbol for division, or sharing into equal groups, is ÷. It’s called the division symbol. This arrangement with equal rows and columns is called an array.

Why are Greek symbols so enduring in math today?
Because European mathematics is very heavily rooted in the mathematics of ancient Greece, and due to the need for many symbols to represent constants, variables, functions and other mathematical objects, mathematicians frequently use letters from the Greek alphabet in their work.

Did the ancient Greeks use the Attic numerals?
Though there was some steamlining of its use, these symbols were used in a similar way to the Egyptian system, being that symbols were used repeatedly as needed and the system was non positional. By the Alexandrian Age, the Greek Attic system of enumeration was being replaced by the Ionian or alphabetic numerals.
How did ancient Greeks do maths?
Greek writers seldom refer to calculation with alphabetic numerals. Addition, subtraction, and even multiplication were probably performed on the abacus (Florian Cajory, A History of Mathematics, p. 65). The operation is explained sufficiently by the modern numerals appended. In case of mixed numbers, the process was still more clumsy.
