 Even the French language today shows remnants of a Gaulish base-20 system in the names of the numbers from 60 through 99.For example, sixty-five is (literally, "sixty [and] five"), while seventy-five is (literally, "sixty [and] fifteen").The Yuki language in California and the Pamean languages in Mexico have octal (base-8) systems because the speakers count using the spaces between their fingers rather than the fingers themselves.
