Creative Countingthe third chapter studies the African creativity in counting systems. For instance, “six” is sometimes expressed as ‘three-three” and “eight” as “four-four” and thus one could expect that etches on tally sticks, such as the Ishango rods, would be done in equal groups of tallies. Other African people

Some of these examples are debatable, such as the alleged golden section proportion in African art or the fractal properties

Multiplication in the Yoruba and “Ethiopian” Way Africa before colonisation. This chapter presents two examples: the multiplications of the Yoruba and of the Ethiopians. The first uses the base 20 and shows that the base 10 is not indispensable for difficult calculations (cf. the question if the Ishango rods were made in base 12?), while the seco

The Ishango Sitele. They carry columns of grouped carvings that intrigue mathematicians ever since. Aspects of the archaeological site are shown in exceptional pictures, until today only published in the official excavation report from 1957, a very rare book. Issues about the dating of the objects are discussed and

Two other columns show the groupings 11, 21, 19, 9 and 11, 13, 17, 19, or and they correspond to 10+1, 20+1, 20-1, 10-1 and the four prime numbers between 10 and 20, again pointing to some arithmetical operations. Since the sum of the t

Missing Linkod merits its title of “oldest finding in the field of mathematics”. Yet, could it in addition pretend to be “at the origin of mathematics” or was it a rather singular finding? This meaning is discussed in this chapter, as it presents summaries of results from linguistics, archaeology, mathematics,
