dear earl

Sang Xu has changed the class teacher.Switched to teaching mathematics.

After hearing the news, some in the class began to cheer, while others felt a little melancholy, while Sang Xu looked indifferent.It doesn't matter, what does it matter who the head teacher is replaced by?

Sang Xu yawned boredly, then turned his head to the door, and saw the light reflected on the bald head of an old man, bulingbiling, Sang Xu narrowed his eyes to avoid the powerful light like a demon mirror, and sighed in his heart: This is the real thing. Bring your own halo!

He was wearing a single shirt, a pair of gloves, and a math textbook under his arm. He walked to the podium and threw the textbook away.

Everyone looked at this teacher and shouted: "Long live!" This bad old man is a well-known old man in the school, who can beat you to pieces!Jiang Shan, an old math man with very few homework assignments but difficult to pull! ! ! ! !Known as the old pervert, the most popular and handsome old man!

The old man started laughing, walked straight to Sang Xu, looked at Sang Xu, and said in a rustic dialect, "Are you the one who is number one in mathematics?"

"... Ang." Sang Xu replied lazily, putting on a rare air.The old man heard that the tone of the caller was not kind, so he naturally had to deal with it.

"Oh, you are not small! Let's see if you can survive to the end in my hands."

The 6th period is the mathematics class. Everyone is looking forward to the old man's class, and they all want to experience how cool it is to be scolded by the old man.

The old man beamed with joy and explained an ordinary example problem on the blackboard.Everyone listened with gusto, suddenly, the old man broke the chalk and stomped his foot, a very subtle and obscene smile appeared on his face, and then said to Sang Xu: "But sometimes, he is bad!"

Sang Xu got hairy from being stared at, and asked secretly: Who is bad?After thinking for a second, I realized that the old man was talking about the questioner, and he was going to talk about the variation of this question.

The old man threw away half of the chalk in his hand, then turned around and continued his lecture.

Coincidentally, the tip of the chalk hit Sang Xu on the head.Sang Xu was very angry, very good, old man, I have made a deal with you!

The math teacher kept on talking about the topic.

Sang Xu interrupted from time to time: "Teacher, you copied the wrong formula."

"..."

"Teacher, you wrote the minus sign in the wrong place."

"Square root two."

"?," the whole class was confused, not knowing what the old man meant.

The old man smiled wretchedly, and said, "I mean. Isn't the square root of two equal to 1.414? See if you all have brains?"

"..." The students who were bullied by the group could only suffer aggrievedly.

"Sang Xu, let me ask you another question."

Sang Xu tilted his head, and instinctively told himself that there must be something wrong with this question.

"How much is one plus one?"

"..." Sang Xu suddenly didn't dare to answer rashly.There must be fraud.

"Oh, stupid boy, don't you know this?"

"... Two." Sang Xu replied uncertainly.

"Silly boy, it's you!"

"?????"

"Er, do you mean that you don't understand me in your ancient language?" The old man smiled treacherously.The class roared with laughter, including Sang Xu's iron son Wang Zi'an.

If you want to scold me, just say it directly, beating around the bush.Sang Xu was dissatisfied, but there was nothing he could do.

Bad old man!Let's tie the knot! !
