There are three common number systems used.
|Information Category:||Number Systems:|
|Number of digits||2 (0,1)||10 (0-9)||16 (0-9,A-F)|
|Reason for existance as is||Computes understand two values easily||Humans have ten fingers, so we made a system based on ten||Easily interpreted to/from binary|
|How much you can count on fingers||1023||10 (technically using Unary)||Not possible|
|Conversions||2^the bit place - 1 if place value is 1, then add everything up for decimal||Awkward converting to either system||Each digit represents a combination of 4 binary bits (0=0000,1=0001,2=0010...E=1110,F=1111)|
|Math||Very easy addition/subtraction, bits just overflow into the next one.||You likely use this one.||Similar to decimal, just 6 more digits|
As you can see, all three have very different uses. The best pick would just depend on what you are doing.
