What feature do numbering systems use to denote the position of digits?

The correct choice is B, which focuses on the concept of place value. Place value is fundamental in numbering systems, as it indicates the value of a digit based on its position within a number. For example, in the number 345, the digit 3 is in the hundreds place, the digit 4 is in the tens place, and the digit 5 is in the ones place. This means that the digit’s value is determined not just by the digit itself but by its location in the overall number.

Understanding place value is essential for performing arithmetic operations, interpreting numerical data, and ensuring accurate calculations, especially in base-10 systems, which are commonly used. Each position represents a power of the base, contributing to the total value of the number and demonstrating how critical place value is in grasping numeric representation and mathematics as a whole.
