Seeing Lin Yuwei looking dejected, Qianxun couldn't help but laugh, "Come on, it's not like you were the only one who couldn't solve it."
"But you solved it, didn't you? No way, you have to tell me now, how should I do it!" Lin Yuwei stared at Qianxun.
Qianxun saw this and her lips twitched slightly.
Fortunately, it wasn't very troublesome, so she took out a draft paper and quickly explained it to Lin Yuwei.
When Qianxun explained the problem, her words were simple yet crucial, touching on all the key points. Thus, Lin Yuwei, who hadn't even reached the part about derivatives, understood her solution.
Suddenly, Lin Yuwei, surprised, couldn't help but look at Qianxun with admiration. "I heard that Mu Chenfeng didn't solve the last question either! Now, you must have beaten him by at least fifteen points!"
