How to Solve Drop Sum Puzzles

Each puzzle includes a series of digits in rows and columns. No digit can repeat in any row, though they can repeat in any given column. The final solution to the puzzle will be arranged in such a way so that the sums of all digits in each column will equal the large number in that column's bottom row. Each puzzle has one unique solution that can be reached using only simple artithmetic and logic. Good luck!
