Is there any point to the 12 times table?
Twelve has more divisors than ten (1, 2, 3, 4, 6 &amp; 12 vs 1, 2, 5 &amp; 10).  If we were really smart, we&#x27;d switch from base 10 to base 12: many more &#x27;decimals&#x27; (really duodecimals) would be non-repeating.  One can very quickly count by twelves on the joints of one&#x27;s fingers, using the thumb as an index (0-143 is a much larger range than 0-10, and it&#x27;s easier to hold one&#x27;s hands in the shape necessary).  If we were really smart, we&#x27;d switch from base 10 to base 12: many more &#x27;decimals&#x27; (really duodecimals) would be non-repeating.<p>And then there are measures like a gross (144) and a great gross (1,728).  Part of the reason for these traditional measures is that they are more flexible than base-10 measures: an eighth-gross or a third-gross are both integer quantities, unlike an eighth-hundred or third-hundred.
