Puzzle #U-1: Easy Math
- Each row should have every digit from 1-4 exactly once
- Each column should have every digit from 1-4 exactly once
- The cell groups must satisfy the arithmetic rules (+ addition, – subtraction, × multiplication, / division)
- For example, if a group of two cells has a "5 +" rule, the two cells must give the number five when added together (either 1 and 4, or 2 and 3)
- The order of the digits in the boxes doesn't matter in any way (e.g. both 1,5 and 5,1 will satisfy "5 /").
- Input the first two rows as the answer (from left to right, 8 digits total)
| 6 × | 2 / | 5 + | |
| 2 – | |||
| 2 – | 2 / | 5 + | |
| 4 × |
