What is the main difference between positional and non-positional number systems?

In the positional number system, the quantitative value of each digit depends on the position of the digit in the number, and does not depend on the non-positional one.

Remember: The process of learning a person lasts a lifetime. The value of the same knowledge for different people may be different, it is determined by their individual characteristics and needs. Therefore, knowledge is always needed at any age and position.
