Grid Sum – Easy

Keep your arithmetic clean: most Easy mistakes are simple addition slips.

Add carefully (line up digits if needed).
Double-check subtraction before writing the number in ink.
Confirm both row and column totals still match.

If stuck: re-check earlier sums — a small error early can block the rest of the grid.
