You have uploaded a set of KenKen puzzles, each in a 4x4 grid with various arithmetic operations (addition, subtraction, multiplication, and division). Here’s a brief guide on how to solve these puzzles:

### Rules for KenKen Puzzles:
1. **Basic Setup**: Each puzzle has a 4x4 grid, and the objective is to fill in the grid using the numbers 1 through 4, ensuring that no number repeats in any row or column.
2. **Cage Rules**: The numbers in the bolded areas (called "cages") must result in the given value when combined using the operation indicated. For example:
   - In a “7+” cage, the numbers must sum to 7.
   - In a “12×” cage, the numbers must multiply to 12.
   - For subtraction and division, the numbers must differ or divide to result in the specified value.

### Steps to Solve:
1. **Start with Easy Cages**: Look for single-cell cages or cages where only one combination of numbers can work (e.g., “1” in a single cell or "3+" in two cells).
2. **Check Rows and Columns**: As you fill in the numbers, ensure no number is repeated in any row or column.
3. **Use Process of Elimination**: For cages with multiple possibilities, use elimination based on what other numbers are already in the row/column.

Here are some questions to further explore:
1. What are the basic rules of KenKen and how do they compare to Sudoku?
2. How can you approach solving the KenKen puzzle if you're stuck on a cage?
3. What are some strategies for solving larger KenKen grids?
4. How do arithmetic operations in KenKen (like division or multiplication) impact the logic of solving?
5. Can KenKen puzzles be adapted for different grid sizes and difficulty levels?

**Tip**: Always start with the most restrictive cages (like single-cell cages or those involving division) because they usually provide easier clues.
