Positional notation refers to certain number systems which use a finite number of symbols called digits, where value is derived by adding together a series of numbers associated with each digit. The value for each digit is determined by multiplying a fixed number associated with that digit with a number determined by the digit's position. The second number is specifically given by raising some fixed number for a given positional system, called a radix, to the number of positions the digit is to the left of the rightmost digit. A positional notation with n as it's radix is said to be base n. Most native numbers are expressed in base 10. Positional notation is the most dense number system, meaning from a finite set of symbols it's the method for arranging said that requires the placing the l
