Some sequences of equalities may seem surprising, as they do not directly follow classical multiplication rules. In this type of challenge, the difficulty arises not only from calculations but primarily from the ability to identify a hidden logical structure between the different lines. It’s not just about multiplying; it’s about carefully observing the results to understand the transformation applied at each step.
In mathematics, recognizing a pattern is often the key to quickly solving a numerical sequence.
As Henri Poincaré said:
“Mathematics is the art of giving the same name to different things.”
This serves as a reminder that behind different results, a common logic may be concealed.
What This Challenge Allows You to Work On:
- Identifying a hidden rule
- The logic of numerical sequences
- Observation skills
- Deductions
- Consistency verification

What Your Performance Reveals
If you found the answer quickly and correctly, you have excellent logic and good analytical skills.
If you found the answer after some thought, you know how to structure your reasoning and verify your steps.
And if your answer was incorrect or not found, no worries; this type of exercise is perfect for improving method and precision.
Detailed Solution We Found (not necessarily the only or even the correct one)
Step 1: Observe the Rule
We notice that the results follow this logic:
(first number × second number) − third number
Step 2: Verification
6 × 4 − 3 = 24 − 3 = 21
7 × 5 − 4 = 35 − 4 = 31
8 × 6 − 5 = 48 − 5 = 43
9 × 7 − 6 = 63 − 6 = 57
The rule is correct.
Step 3: Application to the Last Calculation
10 × 8 − 7 = 80 − 7 = 73
Final Answer:
73
Conclusion
This challenge demonstrates that some numerical sequences are based on a simple yet hidden rule. By carefully observing the relationships between the numbers, it becomes possible to quickly identify the pattern and find the solution. The key lies in analysis and consistency in reasoning.
