What is front end estimation with adjustment?

Answer

Front end estimation is a system in mathematics whereby one only rounds off and add the numbers in the leftmost place or the very last number on the left. When this is done, all numbers in other places will be zeros except the number in the leftmost place after the numbers are rounded. If the numbers have two digits, one should round to the tens place before adding the leftmost digits or numbers.
