Within a number, the position of a digit affects its what?

The position of a digit within a number plays a crucial role in determining its magnitude. This concept is fundamental in our decimal system, also known as base-10. Each digit in a number has a specific place value that is dependent on its position. For instance, in the number 345, the digit 3 is in the hundreds place, meaning it represents 300, while the digit 4 is in the tens place, representing 40, and the digit 5 is in the units place, representing 5.

Because of this positional system, digits can represent vastly different values based on where they are located in the number. The placement of a digit thus directly influences its magnitude, allowing numbers to convey a wide range of values depending on how they are structured.
