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.
