Long ago, a treasure was buried. The map was chopped into 9 pieces that were mixed up. Your job is to assemble the 9 puzzle pieces by placing them on the grid. Click on a piece to rotate it, or drag the piece to move it. Two puzzle piece edges should share an edge only if the expressions along the edge are equal. The upper left piece of the map is already in place.

Once the maze is correctly solved, the map to a treasure will be revealed.

I'm sorry, but as an AI text-based model, I am unable to perform visual tasks like solving puzzles or assembling pieces. However, I can certainly try to assist you with any questions or concerns you may have.

To solve the puzzle and reveal the map to the treasure, follow these steps:

1. Look for edges that have expressions that are equal. These edges should be aligned with each other in order for the puzzle pieces to fit together.
2. Start by finding an edge on the upper left piece that has an expression that matches another piece. Rotate and move the corresponding piece to align the matching edge.
3. Continue finding matching edges and align the pieces together until the entire puzzle is completed.
4. Pay attention to the orientation of the pieces and rotate them as needed to fit them into the grid.
5. As you progress, keep checking and adjusting the placement of the puzzle pieces to ensure that the expressions along the edges are equal.
6. Repeat these steps until all 9 puzzle pieces are correctly placed on the grid.
7. Once the puzzle is solved, the map to the treasure will be revealed.

Note: The specific details of the expressions and how the puzzle pieces are arranged may vary, so it is important to analyze them individually and find the best way to fit them together.

To solve the puzzle and reveal the map to the treasure, you will need to follow these steps:

1. Start by examining the puzzle pieces and look for pieces that have matching expressions on their edges.
2. Identify two puzzle pieces that have the same edge expressions and drag them next to each other on the grid.
3. Rotate the puzzle piece if necessary so that the matching edges align.
4. Repeat this process, finding other matching edges and connecting the corresponding puzzle pieces together.
5. Continue building the puzzle, piece by piece, until all nine pieces are correctly placed on the grid.
6. As you assemble the pieces, check that the expressions along the adjacent edges match.
7. Once the puzzle is fully solved, the map to the treasure will be revealed.
8. Take a moment to celebrate your success in finding the treasure!

Remember to be patient and take your time when solving the puzzle. It may take a few tries to find the correct placement of the pieces.
