What if we used base 12?
Not only does counting in base-12 allow us to have nicer numbers in division as well as recurring patterns in multiplication, it also paves a smoother path for children to learn basic multiplication.
Who invented the Duodecimal system?
Based on W.T. Harris’ classification for the St. Louis Public Library, the Dewey system was first formulated by the American librarian Melvil Dewey in 1873 for application in the Amherst College Library.
