Opening the Secret Closet of Baba Yaga

To open the secret closet of Baba Yaga, you need to fill each cell on the door with either a plus (+), minus (-), multiplication symbol (*), or a digit (0-9) in such a way that the arithmetic expression formed by the cells evaluates to 12. Additionally, there should be no plus sign to the right of any minus sign. Let's explore different ways to achieve this:

1. One possible solution is to arrange the symbols and digits as follows: - Cell 1: 1 - Cell 2: * - Cell 3: 2 - Cell 4: - - Cell 5: 3 - Cell 6: + - Cell 7: 4 - Cell 8: 5

The arithmetic expression formed by this arrangement is: 1 * 2 - 3 + 4 + 5 = 12.

2. Another solution could be: - Cell 1: 1 - Cell 2: + - Cell 3: 2 - Cell 4: * - Cell 5: 3 - Cell 6: - - Cell 7: 4 - Cell 8: 5

The arithmetic expression formed by this arrangement is: 1 + 2 * 3 - 4 + 5 = 12.

3. Yet another solution is: - Cell 1: 1 - Cell 2: - - Cell 3: 2 - Cell 4: * - Cell 5: 3 - Cell 6: + - Cell 7: 4 - Cell 8: 5

The arithmetic expression formed by this arrangement is: 1 - 2 * 3 + 4 + 5 = 12.

These are just a few examples of how the cells can be filled to satisfy the given conditions. There may be other valid solutions as well. The key is to arrange the symbols and digits in a way that the arithmetic expression evaluates to 12 and there are no plus signs to the right of any minus sign.

Please note that the specific instructions for opening the secret closet of Baba Yaga may vary in different folklore or fictional interpretations. The information provided here is based on the given instructions and does not represent an exhaustive analysis of all possible solutions.
