The numbers we currently know were created by the Hindus and presented to the world by the Arabs. Hence the Indo-Arabic appellation. The practicality of the system based on the use of ten digits, was introduced in Europe by the Italian mathematician, Fibonacci. Until then, Europeans used the Roman numeral system, considered complicated, mainly in relation to the performance of mathematical calculations.
The ease of working with Indo-Arabic numbers is unquestionable, but what becomes intriguing in all this evolution is the name given to the symbols. Many say that the naming concerns issues related to geometry, based on the study of angles. Numbers are considered symbols, and throughout history they have been perfected, reaching this visual notation that we know. The writing of each number in its standard form, that is, without graphic implementations of other peoples, had been associated with Geometry. Watch:
The number 1 has an angle
Number 2 has two angles
The number 3 has three angles
The number 4 has four angles
[...] [...] [...] [...] [...]
Zero has no angle
