Positional notation

Positional notation is a way of writing numbers where the value of each digit depends on its position within the number. In this system, each position represents a specific power of a base, like 10 in decimal or 2 in binary. For example, in the number 345, the ‘3’ is in the hundreds place (3×100), ‘4’ in the tens (4×10), and ‘5’ in the ones (5×1). This method allows us to efficiently represent large numbers using a set of digits, with the base determining how many different digits can be used before adding a new position to the left.
