How do you say the number 57?
Taking Asia’s case in point, different countries call numbers in different structures in their languages.
The Northern Indian Subcontinent and The Arabian peninsula, would say the units digit first, followed by the tens digit. Like in Hindi, 64 would be Chausath (Chau:4, Sath:60) or Chaushatti (Chau:4, Shatti:60) in Bengali.
While the South of India and Manipur along with Central Asia would say 57 with the tens digit first followed by the units place- as fifty seven, much like in English. So in Tamil, 57 is Ambathi eḻu (Ambathi: 50, eḻu:7) or Malayalam Ampathi ezhu (Ampathi: 50, ezhu:7).
Much of East and South East Asia follows a basic form of number structures. For Example in China, 57 is broken down into 5×10+7 and would be called Wǔshíqī (Wǔ:5, Shí:10, Qī:7). 63 would be 6X10+3. In Cambodia, the number system has been simplified further with Number Names existing just for 1 to 5 and the Tens. 6 is called 5+1, 7 is called 5+2.
Finally to the systems that are farthest from the usual. With Bhutan and Georgia both following a vigesimal system or a 20 base system, just like French. Where in 77 would be called 3×20+10+7. Mind boggling calculations.
Numbers are much more diverse than we think they are. @loverofgeography created a post on how numbers are called in Europe, this one shows Asia’s Diversity.
