Crossmath: Number Puzzle

Crossmath is a relaxing number puzzle. Every grid is a crossword made of equations: place the missing numbers so every row and column adds up, subtracts, multiplies, or divides correctly.

How it works
- Tap a blank, then tap a number from the tray.
- Green means the equation is right. Red means something is off.
