The link above is a (pdf) discussion on:
Ancient Babylonian Algorithms
by Donald E. Knuth (Stanford University)
It is about some of the "shortcuts" in mathematics using Base 60 (sexagesimal) numbering system. We still use 60 to count degrees, time, etc. for example.
is that useful?
The pdf is a brief discussion of the Base 60 number system and includes some problem solutions for examples. It is only 7 pages long but assumes a certain basic knowledge of numbering systems and methods of summation (using the capital Greek letter "Sigma"). The Babylonians used a "Rule of Twelve" (5 X 12 = 60) to count using fingers sort of like an abacus to count to twelve, and the other to count the "12's" to get to 60.
