African Mathematics
There is evidence to suggest that African Mathematics began more than 8000 years ago. A carved bone dating from between 9000
BC and 6500 BC was found at Ishango in Zaire. The markings indicate that these prehistoric people used a base-10 number system
(just like we do) and were familiar with prime numbers and the operation of multiplying by 2. A series of notches on the Ishango
bone appear to approximate a lunar calendar, suggesting a fairly sophisticated knowledge of astronomy.
