Behind a seemingly simple equation may lie a common trap. Without careful analysis, it’s easy to make mistakes, especially by neglecting the order of operations. Many people perform calculations in the order they read them, instead of adhering to mathematical rules, which often leads to errors.
As Blaise Pascal once said:
“Mathematics has its reasons that reason itself does not understand.”
In mathematics, this serves as a reminder that one must follow a rigorous method, even for calculations that seem straightforward.
What This Challenge Allows You to Work On

Detailed Solution We Found
Method to Follow
To solve this equation correctly, you need to:
– First, perform the multiplication
– Then, handle the additions and subtractions
– Calculate step by step
– Verify the result obtained
We start with the multiplication:
3 × 6 = 18
The equation becomes:
3 − 18 + 2
Then:
3 − 18 = −15
−15 + 2 = −13
Result
Answer: -13
Conclusion
This challenge shows that a very simple expression can become tricky if one forgets the basic rules. The key is to respect the order of operations and to remain rigorous at each step of the calculation.
