Cross Math — Quick rules

Goal of the game

Fill the number cells so that every horizontal and vertical equation reaches its printed result. The same cell participates in two equations.

On an N×N number grid, use each integer from 1 to N² exactly once across the whole grid: 1–4 for 2×2, 1–9 for 3×3. Keep given numbers.
Operators and results are fixed. Read rows left to right and columns top to bottom.
Use standard precedence: multiplication and division before addition and subtraction; operations at the same priority go left to right. There are no parentheses.
Each division must give an integer at the point it is evaluated. Results can be greater than the largest number you may enter.
