COMMENTS.
Chapter #6. “Endangered Number Systems” is significant for me. The various number system possibilities, people use the digits (fingers & toes).
ATOP is the fingers as 1,2,3,4,5; and, counting to a dozen (1,2,3, … 10, 11, 12) on one hand.
INDIA case study is very significant. ABOVE are the fingers representing the element’: water, earth, heaven, air, fire.
- INDIA is a nation that belief associated with “fingers” preferential “eating utensils”. Fingers are holy in dharmic faiths (Hinduism, Jainism, Buddhism). Eating with your fingers is mathematical science in India’s tradition of knowledge. India has a diversity of languages; and, some language population are at risk.
