What two things did the babylonias have as part of their number system that the egyptians lacked

1) place value system - this means that the same digit could mean different things if it was in a different place: for example in the number 232 each of the two 2s has a different value

2) a system based on the number 60: which means that the Babylonians would write 120 as 2 times 60 and the Egyptians would write it as "100 and 20"

France played a key role in the american revolutionary war (american war of independence; 1775–1783). motivated by the ideals of the new nation which were inspired by the french enlightenment, as well as its long-term rivalry with britain and so as to avenge their territorial losses during the french and indian war, france secretly began sending supplies to the americans in 1775.
