Q n A
The oldest version of number we use today
Different symbols were used for the various multiples of 10, 1oo….
However,
* symbol for zero
NO * place value principle
there are examples of symbols, a few of which are at least somewhat similar to those of today, which have been found in India
Greek; used babylonians’ system and they sometimes needed ‘no parts’ of a given unit were involved
Chinese; 1000 B.C. shang period.
Nine symbols, base-ten, place-value.
Empty blanks of the chinese counting board-> stimulus for the invention of zero symbol
Babylonia; sexagesimal system was positional system(though they didn’t have zero concept)
