The ancient Egyptians and Romans modified this concept and laid down their own numerical system for various practical purposes. Many others like the Mayan system used the base 20 system. The place value system of numbers that has a base of ten uses 10 digits from 0 — 9 for making the positional numeral system work.
This system makes it easier for working in arithmetic rather than other numeral systems. For the purpose of computer science, a modified k positional system is used, which is known as bijective numeration. This website stores cookies on your computer.
