Some equations may seem straightforward, but they actually rely on a rigorous application of the order of operations. In this type of challenge, the difficulty arises not just from the numbers involved but also from the sequence in which the operations must be performed. It is not merely about calculating; it is about following a precise and structured method to avoid any misinterpretation. In mathematics, mastering the rules of priority is essential to ensure the consistency of a result.
In France, several international studies have highlighted that the level of mathematics remains a significant issue. For instance, the results of the PISA survey show that French students aged 15 consistently score below the OECD average in mathematics, with a score close to 474 points (compared to approximately 485 for the OECD average according to the latest editions). Moreover, nearly one in five students faces significant difficulties in fundamental calculation and reasoning skills.
These figures underscore the importance of strengthening the mastery of the basics, as seemingly simple equations can actually help develop logic, methodology, and self-confidence when it comes to calculations.
As Sophie Germain once said:
“Mathematics is a living science, full of movement and truth.”
This reminds us that every equation requires thought and rigor.

Detailed Solution We Found (not necessarily the only one, and sometimes not even the correct one).
Step 1: Priority to Multiplication
Within the parentheses, we start with multiplication:
7 × 7 = 49
The equation becomes:
(77 − 49) ÷ 7
Step 2: Subtraction in the Parentheses
77 − 49 = 28
The equation becomes:
28 ÷ 7
Step 3: Final Division
28 ÷ 7 = 4
Final Answer:
4
Conclusion
This challenge highlights the importance of respecting the order of operations in an equation. By correctly handling multiplication before subtraction, and then performing operations in the right order, a reliable result is obtained. This type of exercise reminds us that rigor and method are essential in mathematics to avoid misinterpretation errors.
