I have to write a paper for my math class about which number system would be the best for a new civilization to adopt. The bases I can choose from are base 2, base 5, and base 6. What are the pros and cons to each of these? I know how to solve problems with bases and what not, but I dunno any pros and cons are to each one. Thanks for any help.
Note: We can't make a decision based off how our anatomy (fingers and toes).
