### Directions for Completing Addition Box Puzzles

1. Understand the Layout:
• Each Addition Box Puzzle consists of several empty boxes arranged in a grid. Some boxes might have numbers already filled in.
2. Objective:
• Your goal is to fill in the empty boxes so that the sum of the numbers in each row and column matches the given totals at the end of each row and column.
• Look at the numbers that are already filled in. These numbers will help you determine the values of the empty boxes.
4. Use Logical Reasoning:
• Use the given totals to figure out what numbers need to go in the empty boxes. For example, if a row must total 15 and one box in that row already has a 5, you know the remaining boxes must add up to 10.
• After filling in all the boxes, double-check that the sums of each row and column match the given totals.
6. Example:
• If a row has a total of 12 and contains three boxes, and one of the boxes already has a 4, the sum of the remaining two boxes must be 8.
7. Tips:
• Use scratch paper if you need to do any calculations.
• If you get stuck, try working on a different row or column and come back later.
8. Have Fun:
• Enjoy the puzzle and challenge yourself to solve it using logical thinking and math skills!
