| 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, |
|
425 |
|
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. |
