Place Value and Face Value

Face Value of a Digit in a Numeral

The face value of a digit in a Numeral is the value of the digit itself at whatever
place it may be :

Thus, in the numeral 24679
The face value of 6 is 6

The face value of 2 is 2 and so on

Take one more example,
The face value of 7 in 173259 is 7. So, face value of 2 in this number is 2.

Place Value of a Digit in a Numeral

Place value of a digit equals to (Face value of the digit) × (value of the place).
The place value of each digit in the number 85,325 is given below :

TTh Th H T O
8 5 3 2 5
5 × ones = 5
2 × tens = 20

3 × hundreds = 300
5 × thousands = 5,000
8 × ten thousands = 80,000
Take another example
The place value form of 1, 32, 579 is :

L TTh Th H T O
1 3 2 5 7 9
9 × ones = 9
7 × tens = 70
5 × hundreds = 500
2 × thousands = 2,000

3 × ten thousands = 30,000
1 × lakh =1,00,000
