What are Math Workbooks a symbol of?

The math workbooks are a symbol of wasted potential. When the therapist's wife, who used to be a brilliant mathematician and therapist, must leave her job to stay at home with their son, she starts filling out hundreds of math workbooks because she is bored and has nothing important to do.

I would add that the math workbooks in this novel also symbolize gender inequality and the societal expectations placed on women in South Korea. This is exactly the conclusion I came to while preparing my research paper, which was expanded and appropriately formatted with the help of https://cn.papersowl.com/math-ghostwriting/. It was hard to read about Kim Jiyoung, who was discouraged from taking an interest in mathematics even though her father gave her notebooks as a child. These prejudices against women in Korean society were reflected in science and many other aspects of Korean culture at that time.
