Concept

  • Place value is defined as the digit multiplied by wherever it is placed, either by hundreds or thousands.
  • Face value is simply defined as the digit itself within a number.

For example: in 256, the place value of 2 is 200 and the face value of 2 is 2.

Calculation

The face value of 7 in 4782 is 7 

The face value of 7 in 32170 is 7

Difference = 7 - 7 = 0
