🧩 Level Information

• Level Number:131
• Question: Since mouse=4, cat=6, and cat upside down=9, input 17 with 9+4+4
• Difficulty: Normal

🎯 Objective

As instructed on the screen, calculate 9+4+4 and enter "17" as the answer.

📝 Solution Steps

1. Read the problem statement carefully and verify that it states "mouse=4, cat=6, cat upside down=9".
2. Focus on the part of the instruction that says "input 17 with 9+4+4" and realize that this formula itself is the hint and the answer.
3. Mentally calculate 9+4+4 and confirm that it results in 17.
4. If there is an input box, tap to activate it.
5. Use the number keys to correctly input "17" (in the order of "1" and "7").
6. After completing the input, if there is a confirm or OK button, tap it to submit the answer.

💡 Hints

• Review the problem statement to see if it already contains 'input 17 with 9+4+4'.
• You do not need to deeply consider the 'reason' for mouse=4, cat=6, cat upside down=9. The latter part of the text is the instruction itself.
• Focus on not just solving the equation, but on 'what exactly you are told to enter'.

🧠 Explanation & Points

This level is not a wordplay or complex rule discovery type; it's a trick puzzle where "the problem statement itself tells the answer." As the first part shows "mouse=4, cat=6, cat upside down=9", many players start to ponder 'why is it 4, 6, 9?' However, in reality, finding that reason is unnecessary, as the phrase 'input 17 with 9+4+4' in the latter part serves as the solution. In other words, the level requires you to "calculate the already given formula and enter the answer," rather than "construct the formula yourself." The calculation itself is simple arithmetic, 9+4+4=17, but thoroughly reading the text and ensuring you do not create your own mystery is a crucial point.

🔍 Common Mistakes

• Spending too much time pondering the logic behind mouse=4, cat=6, cat upside down=9 and delaying inputting the answer.
• Seeing only the numbers 9, 4, 4 and attempting a different calculation (like 9+6, 4×4) on their own.
• Entering the formula itself, such as '9+4+4', instead of '17'.
• Missing the instruction and trying to derive the answer from other screen elements (like the number or shape of illustrations).

🎉 Post-Clear Advice

Once you realize the answer is already written in the text, it becomes a level-like service problem that can be solved in an instant. In the upcoming levels, make it a habit to thoroughly read the problem statement or instruction text to the end.
