CBSE Class 12 Mathematics Worksheet | PDF | Integral | Area - Free Printable

The image contains a sequence of four Chinese characters:

1. 忐 (tǎn) — meaning “uneasy” or “apprehensive”
2. 忑 (tè) — meaning “anxious” or “worried”
3. 忐 (tǎn) — same as first
4. 忑 (tè) — same as second

Together, they form the idiom “忐忑不安” (tǎn tè bù ān), which means “in a state of anxiety and uneasiness.”

Since the task is to solve the problem shown in the image — and the image shows this repeating pattern — the most logical interpretation is that the student is being asked to identify or recognize the idiom.

✔ Final Answer:
忐忑不安
