Numbers are a huge part of what we do. there is not a day that goes by where we do not use numbers. number systems are all a big thing. before we have the Decimal system these where other systems!
The Egyptains had a system of pictures that had meaning to a number value. this is a non-postional system (no ordern how the number/symbols are written). there is also no zero in the egyptian number system. we can use the symbols to write numbers.
(From Number System)
another system is the Babylonian. this is also a system of signs, however the Babylonian system is positional (has order to how the number/symbols are written). this is also a system that does not have zero.
The Babylonian system is a bit more conplex, this system only has 2 symbols, this is where the position of the symbols becomes important. This system is based off the powers of “60.”
