What did ancient Greeks use as numbers?

The earliest numerical notation used by the Greeks was the Attic system. It employed the vertical stroke for a one, and symbols for “5″, “10″, “100″, “1000″, and “10,000″.

Did the Greeks invent the decimal system?

The Greek numbers however, were a decimal (base 10) system. The ancient Greeks did not use numbers as we know them today. Instead, they used letters of the Greek alphabet to express numerical quantity in the same way we are using today in algebraic expressions.

How was math used in ancient Greece?

They were drawn to similarities and differences of natural objects and natural patterns. From this they embraced mathematics for its ability to describe the natural, especially as geometric patterns. Greeks refined analytical methods by introducing deductive reasoning and mathematical rigor in proofs.

Who first used decimals?

Decimal fractions were first developed and used by the Chinese in the end of 4th century BCE, and then spread to the Middle East and from there to Europe. The written Chinese decimal fractions were non-positional. However, counting rod fractions were positional.

How did Greeks write their numbers?

Some Greeks used a system based on writing the first letter of the word for that number. Like in Greek you say Ten “Deka”, so they would draw a D to mean 10. They did this for the first ten letters, and then the 11th letter stood for 20, the 12th letter stood for 30, the 13th letter stood for 40, and so on.

Why do we use Greek symbols in math?

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.

How did Greeks do math without zero?

Ancient Greek mathematics did not use 0 in their numbers system, but of course worked around it by using words for numbers. Zero becomes necessary only with place-value numeration. Babylonian arithmetic was somewhat place-valued, even though they did use different symbols for (for example) 600 and 6000.

Who invented decimal in world?

Decimal fractions had already been introduced by the Flemish mathematician Simon Stevin in 1586, but his notation was unwieldy. The use of a point as the separator occurs frequently in the Constructio. Joost Bürgi, the Swiss mathematician, between 1603 and 1611 independently invented a system…

Did the ancient Greeks have a decimal system?

During the classical and early Hellenistic period (until 200 BC) Greeks did not use any positional system, they had their own which was decimal but not positional. The units from 1 to 9 are assigned to the first nine letters of the archaic Greek alphabet from $\\alpha$ to $ heta$.

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.

Is the Greek number system good for calculating?

However, calculation lends itself to a great deal of skill within almost any system, the Greek system being no exception. First, we note that the number symbols were the same as the letters of the Greek alphabet.
