Huang Min-huang, an associate professor of mathematics at National Taiwan University, believes that proofs of this sort may be still included because the writers of the texts think that the logic behind them is "beautiful." Huang notes, "Those who have studied math want to increase exposure to the legacy of great mathematicians."
台大數學系副教授黃敏晃認為，類似這樣的證明題還留在教材裡，或許是因為歷來編寫教科書的人認為它的論證邏輯「實在漂亮」，「學數學的人希望發揚光大數學傳承」，黃敏晃說。
