What exactly were they calculating? The evil tragedy is, when whites eventually came in to contact with mathematics they would come to use it to count African slaves as they were boarded on to ships bound for America and Europe.
Were women our first mathematicians? It was first thought to be a tally stickas it has a series of what has been interpreted as tally marks carved in three columns running the length of the tool, though it has also been suggested that the scratches might have been to create a better grip on the handle or for some other non-mathematical reason.
The tomb of Qalhata at [ Generally they ignore the history of mathematics in Africa south of the Sahara and give the impression that this history either did not exist or, at least, is not knowable, traceable, or, stronger still, that there was no mathematics at all south of the Sahara.

The etchings on the bone are in three columns with marks iwhango grouped into sets, leading to “various tantalizing hypotheses”,  such as that the implement was used as a counting tool for simple mathematical procedures or even to construct a numeral system.
Marshack later concluded, on the basis of his microscopic examination, that it represented a six-month lunar calendar.
The third column has been interpreted as a “table of prime numbers”,  but it is more likely to be a coincidence. Numbers and the Making of Us: The first bone has been subject to a lot of interpretation.
