How does the positoin of a digit relate to its value?

The position of a digit in a number determines its value based on the place value system. Each position corresponds to a power of 10, where the rightmost digit represents units (10^0), the next position represents tens (10^1), followed by hundreds (10^2), and so on. For example, in the number 345, the '3' is in the hundreds place (300), the '4' is in the tens place (40), and the '5' is in the units place (5). Therefore, the overall value of the number is the sum of these positional contributions.
