(1) Base 11 is called undenary, Base 12 is called duodenary or duodecimal , Base 16 is called hexadecimal.

(5) Thus the vast swath of earth subdued by Alexander the Great immediately becomes a desire-object for the contentious successors, who carve it up duodecimally ; they run into Parthian and Hindu limits in the East, where the locals respond mimetically to the pattern.

(6) His plan would teach people to count duodecimally with two new digits: eight nine deck ell ten; and this by itself would recommend it, as duodecimal arithmetic is a coming reform.

(7) I'll abbreviate it so that ÔÇÿ12 -ÔÇÖ stands for ÔÇÿ duodecimally negativeÔÇÖ, ÔÇÿ7 +ÔÇÖ stands for ÔÇÿseptimally positiveÔÇÖ and ÔÇÿ12 + +ÔÇÖ stands for ÔÇÿduodecimally double-positiveÔÇÖ.

(8) Most common timings could be handled duodecimally with no need for time signatures.

(9) The figures, however, are obviously artificial, for they are usually round sums and, like the geld, frequently duodecimally based.
