Multiplication tables for bases 2, 8, 12, and 16
When doing multiplication in bases other than 10, it can help to
have a table of single-digit products handy, analogous to the 'times
tables' that we all learn in our earliest math classes.
Below, you can find tables for
base 2 (binary),
base 8 (octal),
base 12 (duodecimal), and
base 16 (hexadecimal).
