Topic: reason why 1=.99999....99(10/9) and why 1/3 = .333333......33(1/3),
never that nonsense 1=.999.... 1/3 = .3333.....

Dont ask so difficult questions, AP brain farto
cannot answer. He is even not aware that Newton

introduced compleat Quotients to calculate with
rational numbers, and that for example sqrt(2)

doesn't have compleat Quotient representation.
Newton doesn't use our modern name rational

numbers, but he writes:
"This method of reduction (*) may be thus very
conveniently imitated in numbers..."

An it appears in book part called "Annotations",
so I guess its not from Newton himself.

sqrt(2) comes only later, and for example on page
171 the author atributes some of the developments

to A. D. Moivre:

In the theory of series, de Moivre developed a
polynomial theorem encompassing Newton's binomial
theorem and, in particular, a theorem of recurrent
series useful in the calculus of probability.

(Thats maybe also where Euler got his diverging
series from, not sure)

(*)
The geometric series from the previous section.
