Africans Made No Worthwhile Contribution to Mathematics
The earliest numerical record found to date, about 37,000 years old, comes from the Lebombo Mountains between Swaziland and South Africa. It is a fossilized piece of baboon bone with 29 well-defined notches. The notches are evenly spaced and appear to represent a lunar calendar.
About 25,000 years ago, on the shores of Lake Rutanzige (formerly called Lake Edward) between Zaire and Uganda, a pattern of tallies was carved on a bone by the Ishango people. This Ishango pattern suggests some understanding of the principle of multiplication and division by two and prime numbers.
An analysis by Dr. Stephen Chrisomalis of McGill University in Montreal suggested the Greeks borrowed their number system, alphabetic numerals from Egyptian demotic numerals, used in Egypt from the late eighth century B.C. until around A.D. 450.
