It is a system in which all numbers up to and including 19 are represented by a single digit. 20 would be the first double-digit number. An example of how to represent the first 40 numbers could look like this: 1,2,3,4,5,6,7,8,9,a,b,c,d,e,f,g,h,i,j,10,11,12,13,14,15,16,17,18,19,1a,1b,1c,1d,1e,1f,1g,1h,1i,1j,20.
In this system, a= our number 10, b= our 11, etc., 10= our 20, etc., 19= our 29, 1a= our 30, and 20= our 40. Our 200 would be the first 3-digit number, and would be written as 100.
It is the number 16.

Mayan
The base 20 number system is called the vigesimal numeral system.
The Mayans used a similarly number system to the Babylonians but chose different numbers as the bases. Their number system had a base 5 within a base 20.
Probably it was the ancient Babylonians whose number base was 60 or maybe the ancient Mayans whose number base was 20
20 is the base the Mayan mathematics use back then
The Mayans based on the 20 number system because of 10 fingers and 10 toes. The Mayan number was very useful to the Mayans in the past. Today, they use the modern number system we use today.
