The image contains a mathematical puzzle in French. The instructions state:

"Placez tous les nombres de 1 à 9 dans les petits disques gris de façon que la somme des nombres se trouvant sur chaque grand cercle soit toujours la même."

Translated, this means: "Place all the numbers from 1 to 9 in the small grey circles in such a way that the sum of the numbers on each large circle is always the same."

The image shows four overlapping large circles, each with three grey circles inside. The challenge is to place the numbers from 1 to 9 in these grey circles so that the sum of the numbers in each of the four large circles is equal.

Would you like me to solve this puzzle for you or provide a step-by-step guide on how to approach it?

Here are 5 relative questions:

1. What is the significance of using numbers from 1 to 9 in such puzzles?
2. How does symmetry help in solving this type of puzzle?
3. What strategies can be applied to ensure all circles have the same sum?
4. Can this puzzle have more than one solution?
5. How does the placement of numbers affect the sum in overlapping regions?

Tip: Start by calculating the total sum of numbers from 1 to 9 and divide it by the number of overlapping circles to help guide the placement.
