有什麼好笑的數學笑話嗎？_風聞

An engineer, a mathematician, and a CPA each interviewed for a CFO opening and all three did equally well. So, in order to break the tie, the boss asked each one the same devious question, “What’s 2 + 2?”

The engineer responded quickly “4” - and was told to go home.

The mathematician thought about it and said, “It lies between 3.999… and 4.0001” - and was also let go.

The CPA thought about it for a few minutes, looked around, checked for any hidden microphones and then quietly asked, “What do you want it to be?” He got the job.

一名工程師、一名數學家和一名註冊會計師分別參加了首席財務官職位的面試，三人的表現都一樣好。所以，為了打破僵局，老闆問了每個人同樣狡猾的問題:“2 + 2等於多少?”

工程師迅速做出了“4”的反應，並被告知回家吧。

數學家想了想，説:“它介於3.999…和4.0001之間。”

會計師想了幾分鐘，環顧四周，看看有沒有隱藏的麥克風，然後平靜地問:“你想要多少?”然後他得到了這份工作。

Mother is 21 years older than her son.

In six years she will be five times older than her son.

Question: Where is Dad?

母親比兒子大21歲。

六年後她將比她兒子大五倍。

問：爸爸在哪裏?

Solution:

Age of son at this moment = x

Age of mother at this moment = y = x + 21.

Age of son after 6 years = x + 6

Age of mother after 6 years = x + 21 + 6

After six years mother is five times older than son = (x + 6) * 5

We solve this system of equations:

解：

此時兒子的年齡x

此時母親年齡 y = x + 21。

六歲後兒子年齡 x + 6

母親6歲後的年齡 x + 21 + 6

六年後，母親比兒子大五倍(x + 6) * 5

我們求解這個方程組:

5 * (x + 6) = y + 6

5 * (x + 6) = x + 21 + 6

5x + 30 = x + 27

4 x = -3

x = - 3/4

At this moment son’s age is - 3/4 of the year, which is -9 months, which means at this moment daddy is on mother.

5 * (x + 6) = y + 6

5 * (x + 6) = x + 21 + 6

5x + 30 = x + 27

4x = -3

x = - 3/4

在這個時候，兒子的年齡是- 3/4，也就是-9個月，這意味着在這個時候爸爸在媽媽身上。

Once a Mathematician was giving an interview.

Interviewer : Suppose you had an urgent and important meeting in your office and you are late and running fast to reach the office as early as possible and at the same time you see a building caught by fire with some people in serious problem in that building.Then what will you do??

Mathematician: Mam I will help the people caught in fire in the building by calling fire brigade.

Interviewer: Ok, same question but now there is no fire in the building.

Mathematician: Mam , I will set fire in the building and then the solution of this problem became same as the previous one.

有一次，一位數學家在接受採訪。

面試官：假設你在辦公室裏有一個緊急而重要的會議，你遲到了，趕緊儘可能早地趕到辦公室，同時你看到一棟大樓着火了，大樓裏的一些人都遭遇了嚴重的問題。然後你會做什麼?

數學家：嗯…我會打電話給消防隊幫助大樓裏失火的人。

記者：好的，同樣的問題，但是現在大樓裏沒有着火。

數學家：嗯…我要到大樓裏放火，然後這個問題的答案就變成和前一個一樣了。

Married couple, dealing with an issue …

“You love your mathematics more than you love me!”

“Not so, darling, I love you much more.”

“Then prove it!”

“OK. Let R be the set of all lovable obxts…”

已婚夫婦，處理一個問題…

“你愛你的數學勝過愛我!”

“不是這樣的，親愛的，我更愛你。”

“那就證明它!”

“好吧。先令R是所有可愛東西的集合……”
