If I round 2,420
to the nearest ten thousand. Yet this number is lacking a digit or rather is
incomplete.
Assuming that we
add three zeros to the digit number thus becomes, 2,420,000 and we want to
round it off to the nearest ten thousand it will be 2,420,000 the same digit.
But if we add only
one zero to complete the digit, 24,200 the number becomes 20,000.
