A positional number system is one where the position of a digit is significant to its value. For instance, the Hindu-Arabic system denotes the decimal symbol 42 to mean forty tens and two units, the sum of which gives us the number forty-two. Note that 42 is not a number, it is a symbol; forty-two is the actual number represented by that symbol. The digits in the symbol are valued according to their position, hence the Hindu-Arabic system is a positional number system.
The Hindu-Arabic system can be applied to any numeric base, whether binary (base 2), octal (base 8), decimal (base 10), hexadecimal (base 16) or sexagesimal (base 60). When working with integer values (whole numbers), the digits from right-to-left represent an increasing power of the base, starting from 0. When working with fractions of a unit, the digits from left-to-right represent a decreasing power of the base, starting from -1. Multiplying the digit by its positional value gives its actual value within the symbol.

By contrast, the Roman numeral system is non-positional, because the physical position of a digit within a symbol has no bearing on its value. An X always denotes the value ten regardless of where it appears within the symbol.

Non-positional systems typically do not have a symbol to represent the value zero. The reason is not that the notion of "nothing" didn't exist, it was simply that you do not need a symbol for zero when counting or making a tally; you only count the things you have, not what you do not have. Hence the natural numbers (counting numbers) begin at one, not zero.
However, in positional systems, you need a place-holder to denote that a position has no value. In some systems a space would be used, but in Hindu-Arabic, the digit 0 is used. Thus the decimal symbol 402 denotes that the value has no tens.

A polynomial of degree zero is a constant term

The grouping method of factoring can still be used when only some of the terms share a common factor A True B False

The sum or difference of p and q is the of the x-term in the trinomial

A number a power of a variable or a product of the two is a monomial while a polynomial is the of monomials

Definition of Non positional number systems?

In the non positional number system, the value of the number does not depend upon the position of "digits" used to represent the number. Unlike the positional number system, in non positional system every number, as a whole, is represented as a combination of certain specific symbols. Therefore, according to me, there is no such a notion of "digits" in the non positional system. The classic example of non positional number system is the Roman number system in which the numbers are represented by certain specific symbols: I for 1 II for 2 X for 10 XX for 20 etc.

What are positional muber system?

I think you meant positional number system or Positional Notation. In computer science when we talk about positional notation where talking about the binary(base 2) and hexadecimal(base 16) system. So for the most part a positional number system is a counting system. We for example use a base 10 counting system.

Difference between positional and non positional number system?

A positional notation numeral system in which each position is related to the next by a constant multiplier of that numeral system. For each position that the number is in, in that system has a relative symbol or meaning, and in a way relates to the number directly next to it. The total value of a positional number is the total of the resultant values of all positions. In a non-positional number system, each number in each position does not have to be positional itself. Every system varies by country and it depends on symbols and values set by the people of that country. For example, the Egyptians use Hieroglyphics, and the Greeks use a numeral system.

What are non positional number systems?

A non-positional number system is the one in which the symbols that are used to represent a number will have its own place value. For example, in the early ages stones and sticks were used to count a number, with one stick for 1, a hundred sticks for 100 and so on. The position or placing will not make any change.
