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.
The Rules
Fill the crossword-style grid with digits so every row and column's arithmetic equation works out correctly.
Step by Step
- 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.
- Once a digit is locked in from one direction, immediately plug it into the crossing equation — it often reduces that second equation to a single remaining unknown.
Frequently Asked Questions
What operations does Cross Math use?
Addition, subtraction, multiplication, and division all appear, following standard left-to-right order of operations.
Is Cross Math good for practicing arithmetic?
Yes — it's a popular way to sharpen quick mental math while still being a logic puzzle at heart.
What order of operations does Cross Math follow?
Standard math rules, applied in the direction the equation reads — left-to-right for a row, top-to-bottom for a column — exactly as the fixed operator symbols show.
