Feedback Each digit has a fixed position called its place
Each digit has a value depending on its place called the place value of the digit.
The face value of a digit for any place in the given number is the value of the digit itself
Place value of a digit = (face value of the digit) × (value of the place).
Hence, the place value of 6 in 64 = 6 x 10 = 60.
