Question :
What is 'Place Value' ?

Answer :
The common scale of notation we use in our day-to-day life is the Denary System - base 10.
In this system each digit used is said to have place value which is a power of 10.
Each digit has a different place value.
For Example,
The first digit is called the hundreds' place. It tells you how many sets of one hundred are in the number. The number 425 had four hundreds.
The middle digit is the tens' place. It tells you that there are two tens in addition to the four hundreds.
The last or right digit is the ones' place which is five in this example. Therefore, there are 4 sets of 100, plus 2 sets of 10, plus 5 ones in the number 425.
