I know we use a base 10 number system to count and a base 2 number system as binary for computers, but what are some examples of what we use other number bases for (base 3, base 4, base 5, etc...)?

Thank you all for your answers! I feel like I learned more here than in all 13 years of grade school.

Base 8 (octal) used to be used a lot in computing; even today base 16 (hexadecimal) is.

They're useful because they are far shorter to write and easier to read than binary, yet they line up in columns that match the bytes and words used in binary. (I.e. a number that's a fixed number of bits long will also be a fixed number of hexadecimal digits long, while in decimal it might vary in length)
