This is the system in which the position of a digit in a number determines its value. We know that the place value is the basis of our entire number system. Place value has an important role to play in defining the algorithm for addition as well as subtraction. Importance of place value in addition and subtraction Therefore, the number 65,471 is different from 17,645 because the digits are in different positions. The place value of a digit in a number is the value it holds to be at the place in the number. Place value is the basis of our entire number system.
