Is Zhuge Liang good at calculation? ("Calculation" here refers to mathematics, arithmetic and the like) Are there any examples where he is good at arithmetic?

Romance of the Three Kingdoms is about Zhuge Liang, who is very clever and can always judge his opponent's strategy according to the situation, thus winning the enemy.

It can also be said that he is a divine operator, who can tell fortune and count fingers, but he is definitely not an arithmetic operator.

Ancient famous arithmetic experts include Zu Chongzhi, Zuheng and Liu Hui. The main works on arithmetic include Zhou Zhi Shu Jing and Nine Chapters Arithmetic, but there is no record of Zhuge Liang's arithmetic.
