The puzzle in the image asks if it's possible to fill the grid with numbers from 1 to 9 (without repetition) in such a way that the operations both vertically and horizontally are correct and result in the specified values on the right and bottom of the grid.

### Key points from the image:
- You need to place the numbers 1 through 9 in the empty spaces.
- Operations (addition, subtraction, multiplication) are indicated in between the spaces.
- Results are provided at the end of each row and column.

### Operations and Results:
- First row: \(( \_ + \_ ) \times \_ = 90\)
- Second row: \(\_ \times \_ + \_ = 16\)
- Third row: \(\_ \times \_ - \_ \times \_ = 10\)
- Fourth row: \(\_ + \_ + \_ = 13\)
- First column: \(\_ \times \_ \times \_ = 64\)
- Second column: \(( \_ + \_ ) \times \_ = 10\)
- Third column: \(( \_ + \_ + \_ ) = 15\)

Let me analyze this puzzle and find the solution.It appears that there is no valid solution using the numbers 1 through 9 that satisfies all the constraints in the puzzle as defined. This might suggest a deeper complexity to the puzzle, or the possibility that some of the conditions need to be interpreted slightly differently.

Would you like to explore this further by relaxing certain conditions, or should I guide you through the setup and logic step-by-step? Let me know if you have any other questions or if you'd like additional help.

### Related questions:
1. Could we approach the puzzle with a different operation sequence?
2. Are there any variations where specific constraints (e.g., non-repetition) are loosened?
3. What would the puzzle look like if only one or two constraints were removed?
4. Is there an easier way to check solutions visually before testing permutations?
5. Could substituting any of the numbers help resolve this puzzle?

**Tip**: Breaking down each row and column individually might simplify the solving process if you struggle with all constraints at once.

Can you place numbers 1 through 9 in the grid without repetition so that the operations (vertical and horizontal) result in the correct answers?

Solve the number placement puzzle by filling the grid with numbers 1 through 9 without repetition. Perform the correct mathematical operations to match the given results both vertically and horizontally. Suitable for students in Grades 6-9.
