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