- Solving: fill each blank with a digit from 1 to 9 so that every row and every column is a correct equation. There is always exactly one way to fill the grid.
- Solve on screen: click any blank and type a digit, or use the arrow keys to move between blanks. Check highlights anything wrong.
- Printing: “Print / PDF” prints the blank puzzle with its equations — up to 2 per sheet. “Print Answers” prints the completed grid.
The rules of cross math
- Fill every blank cell with a digit from 1 to 9.
- Every row is an equation: the first two digits combined with the operator must equal the result on the right.
- Every column is an equation the same way, read from top to bottom.
- Work strictly left to right (and top to bottom) — there is no multiplication-before-addition precedence.
- Division is always exact (no remainders), and every equation's result is a positive whole number.
- There is exactly one solution, reachable by logic and simple arithmetic.
Frequently asked questions
What is a cross math puzzle?
A cross math puzzle is a crossword-style grid of numbers where every row and every column is a math equation using +, −, × and ÷. Some digits are already filled in as clues; your job is to work out the missing digits so that every row and every column is true.
How do the equations in a cross math puzzle work?
Each line reads left to right (or top to bottom) with no operator precedence: digit, operator, digit, equals, result. For example, 2 + 3 × 4 means (2 + 3) × 4 = 20, not 14. Division is always exact — no remainders or fractions — and every result is a positive whole number.
