Some equations may seem simple, but they often hide a trap related to the order of operations. In this type of challenge, the difficulty does not arise from the numbers themselves, but from the sequence in which the operations must be carried out. It’s not just about calculating quickly, but about applying a rigorous and logical method.
In mathematics, a simple mistake in the order of operations can completely change the final result.
In France, mathematics assessments regularly show that mastering the fundamentals remains an important challenge. These exercises are thus an excellent opportunity to practice, solidify your foundation, and develop a reliable calculation method. Here, the key is not speed, but the correct application of mathematical rules. Plus, there’s nothing healthier and more natural than exercising your brain.
As the great master Albert Einstein said:
“Logic will get you from A to B. Imagination will take you everywhere.”

What Your Performance Reveals
Quickly and correctly found result: you have excellent analytical skills.
Result found after some thought: you know how to structure your reasoning.
Incorrect or unanswered result: no problem, these challenges are meant for progress.
Detailed Solution We Found (not necessarily the only or even the correct one).
Step 1: Solve Inside the Parenthesis
We start by performing the division:
7 ÷ 7 = 1
The equation then becomes:
7 × (1 + 6) − 9
Step 2: Complete the Parenthesis
1 + 6 = 7
The equation becomes:
7 × 7 − 9
Step 3: Perform the Multiplication
7 × 7 = 49
The equation then becomes:
49 − 9
Step 4: Perform the Final Subtraction
49 − 9 = 40
Final Answer:
40
Conclusion
This type of equation highlights the importance of strictly adhering to the order of operations. A simple parenthesis can completely alter the final result if misinterpreted. The essential part here is to follow each step in the correct order to arrive at a reliable and logical solution.
