Encoding information

Encoding information. J.-D. Chatelain. Almost whole Humanity today uses the same ten symbols called "Arabic numerals" and scored 0, 1, 2, 3, 4, 5, 6, 7, 8 and 9. Counting. The ten symbols combined allow to represent any number that is said then expressed in base 10 , or as decimal .
