Research the rationale for why that particular number system was used and think about the ways in which that number system is better or worse than base-10.

2. Though it is not know for sure, the most commonly accepted theory is that the base-60 system was adopted when eastern traders using the duodecimal system (base-12) started trading with civilizations using a quinary (base-5) system. In order for both groups to understand each other, they merged the two systems and created a base-60 system that both groups could understand (since 5 x 12 = 60). The merging of cultures that formed Macedonia coincided with this merging of two different number systems.
3. This sexagesimal system still has many impacts today, 6000 years after it was created. We use a sexagesimal system for keeping time, dividing each hour into 60 minutes and each minutes into 60 seconds. This system is also what we used for angles, with 360° (60*60) making up a circle.

10 in base-60 = 60 in base-10
16 in base-60 = 66 in base-10
100 in base-60 = 3600 in base-10
121 in base-60 = 3,721 in base-10]]> 2022-06-06 17:00:36 UTC https://padlet.com/cjmasini/x5d98t76y79kr9gs/wish/2212461660 cjmasini https://padlet.com/cjmasini/x5d98t76y79kr9gs/wish/2212463633 For each civilization, answer the following questions:

1. What number base did the civilization use?
2. What was the reason behind the choice of that number system? This could be because of cultural reasons, or because of numerical reasons.
3. Did this number system influence modern day systems, either worldwide or in the particular region it was from?
4. Convert the following numbers in the base system for your civilization into what they would be in base-10: 10, 16, 100, 121   ]]> 2022-06-06 17:02:25 UTC https://padlet.com/cjmasini/x5d98t76y79kr9gs/wish/2212463633 cjmasini https://padlet.com/cjmasini/x5d98t76y79kr9gs/wish/2212478638 State standard: 2-DA-07 - Representing data using multiple encoding schemes]]> 2022-06-06 17:15:26 UTC https://padlet.com/cjmasini/x5d98t76y79kr9gs/wish/2212478638 cjmasini https://padlet.com/cjmasini/x5d98t76y79kr9gs/wish/2215132966 1. The Mayans used a vigesimal, or base-20, counting system.
2. For the Mayans, some numbers were considered more sacred than others. 20 was one of those numbers because it represented the number of fingers and toes you could count on. 
3. While the Mayan counting system did not influence any of the systems used today, the Mayan calendar was incredibly advanced for its time and was accurate until its end.
4. 
10 in base-20 = 20 in base 10
16 in base-20 = 26 in base 10
100 in base-20 = 400 in base 10
121 in base-20 = 441 in base 10]]> 2022-06-08 15:22:45 UTC https://padlet.com/cjmasini/x5d98t76y79kr9gs/wish/2215132966
