Answer 1

Answer

First of all what is face value ?

Face value is the actual value of a digit in a number. To get the place value of a number, we multiply the digit value with its numerical value. For example, in the number 452, the place value of 5 is (5 × 10) = 50, since 5 is in tens place. The face value of a digit is the number itself.

Ex 567 here face value of 6 is 6 but place value is 60.

Now onto question

Difference between place value and face value is

7000 - 7 = 6993 is your answer.
