Numbers

Numbers are our way to quantify, label, and organize the world around us in a logical manner. However, the systems used to obtain this goal differ geographically, historically, and by relative utility. All questions pertaining to numbers, including historic labeling systems, bases of numerical systems, constants, and the various ways they're grouped together, should be placed into this category.

What is the connection with Hindu Arabic numerals and that which involves angles?

This question has already been answered by myself but someone else has entirely deleted the original answer probably for plagiarizing purposes so here we go again:-

It is written that at one time in the distant past the Hindu-Arabic numerals or digits of 1, 2, 3, 4, 5, 6, 7, 8, 9 and 0 were once encoded with secret geometrical symbols inasmuch that the first digit of 1 had either an arc or an angle of 36 degrees hidden in it and then thereafter each consecutive digit was increased by increments of 36 degrees by means of arcs and angles or a combination of both in which the digit 0 finally consisted of 360 degrees.

As a consequence of these concealed codes the digit degree sum of any number from 1 to infinity would always finally total to 9 degrees as the following example shows:-

Digit degree sum of 2357 = 36*(2+3+5+7) = 612 => 6+1+2 = 9 degrees

Over the past thousands of years Hindu-Arabic numerals have been transformed into the configuration that we use today but the zero figure at one time probably resembled a circle which even today consist of ten 36 degree arcs amounting to 360 degrees.
