About Cross Math

Play Cross Math online for free. Place digits into a crossword-shaped grid of arithmetic equations so every row and column works out correctly, using addition, subtraction, multiplication, and division together.

How to play Cross Math

  1. The grid is laid out like a crossword, with operators and equals signs fixed in place.
  2. Fill the empty cells with digits so every horizontal and vertical equation is true.
  3. Follow standard order of operations left-to-right and top-to-bottom as shown by the grid.
  4. The puzzle is solved when every equation in the grid checks out.

Tips & strategy

  • Start with equations that only have one empty cell — they solve immediately.
  • Filling one cell often completes both a row and a column equation at once, so recheck crossings after every move.
  • Division and multiplication clues narrow candidates fastest — solve those rows first when you can.
