                         For addition and subtraction, the numbers must be placed properly in the columns
                           according to the place value system.

                         For addition involving regrouping, carry the number to the next column to the left
                           (if required) and add.
                         For subtraction involving regrouping, borrow from the column to the left (if required)
                           and subtract.
                         Estimated sums and differences are not actual but give an idea where accuracy is
                           not essential.
