Who invented symbols

But even with this system, it was still a cumbersome method for writing large numbers. Early number systems all have one thing in common. They require someone to write down many symbols to record a single number and create new symbols for each larger number. A positional system allows you to reuse the same symbols, by assigning the symbols different values based on their position in the sequence. Several civilisations developed positional notation independently, including the Babylonians, the Chinese and the Aztecs.

By the 7th Century, Indian mathematicians had perfected a decimal or base ten positional system, which could represent any number with only ten unique symbols. Over the next few centuries, Arab merchants, scholars and conquerors began to spread it into Europe.

A key breakthrough of this particular system which was also independently developed by the Mayans was the number 0. Having and using 0 helps make writing down numbers clearer and easier for everyone to understand. The Babylonians invented a base 60 system, which is still the foundation of the way we now tell time: each day is made up of 60 minute hours and 60 second minutes.

Modern students are no longer worrying about the best way to record numbers. In , he received the George R. He lived in Lincoln, Massachusetts where he raised miniature sheep.
