Numbers, Numbers Oh My!

23 Sep

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.

1= 10= 100= 1000=

(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.”

______       _____    ___      ____

216000’s    3600’s     60’s      ones

Our number system is the Decimal system. the Decimal system is a positional system and has a zero.

these are only three of the number systems but there are many more!
