Grid Sum – Easy

Work systematically: don’t guess — calculate.

Choose the row/column with the fewest blanks.
Fill in the missing number using subtraction from the total.
Cross-check immediately with the intersecting line.

Momentum tip: after each correct placement, scan the whole grid again — something else may now have only one blank.
