Third Master Yan Bugui's Shock!
Class started!
Ye Fan sat in his seat and calmly took out his textbook.
There were two classes in the morning, both of which were mathematics.
In this era, it was also called math class.
It was all the same thing.
All the students stood at attention. Soon, a familiar figure appeared in Ye Fan's eyes.
Yan Bugui!
That's right!
It was the third uncle of the courtyard house. He was an old teacher at Red Star Primary School. He taught fifth-grade mathematics and was very qualified.
But it was a pity!
A school and a factory could not be compared. Although it sounded expensive and had a high social status, the actual income was pitifully low.
He was a level-eight teacher, and his monthly salary was about the same as He Yuzhu's, 32.50 yuan.
Yi Zhonghai, who was also a level-eight fitter, had a salary of more than ninety-nine yuan.
The difference was three times!
Yan Bugui's family of six relied on his monthly salary of 32.5 yuan to survive, so their lives were quite tight. They had to calculate!
A famous scheme.
However, after scheming and scheming, in the end, the father was unkind and the son was unfilial.
This was a story for the future!
" It's time for class, don't talk anymore…" Yan Bugui pushed up his black-rimmed glasses and said,"" There are two classes this morning. In the first class, I'll teach you about addition and substitution of decimals. In the second class, we'll have an arithmetic test to see how many marks you can get..."
Not mentioning the exam was still alright!
At the mention of the exam, all the students trembled.
"Oh, right…"
"I learned some unit conversion some time ago…I'll give you guys a test before class today to see how you're doing…" Yan Bugui said.
"Xie Erdun, stand up and answer…"
In the first row, a little fatty stood up.
"How many kilograms is a ton?" Yan Bugui asked.”
"Teacher Yan, it's a thousand kilograms…" Xie Erdun said.
"Not bad!"
Yan Bugui smiled and said," It seems like you have a good grasp of it. How many meters is a kilometer?"”
"1,000 meters!" Xie Erdun said.
"How many centimeters is one meter?"
"100 centimeters!" Xie Erdun said.
"Good!" Yan Bugui was very happy. The knowledge that he had taught his students was not bad.
"Then let me ask you, how many square centimeters is one square meter?”
Xie Erdun's face revealed a trace of panic.""One…one…one hundred?"
Yan Bugui frowned!
"No, it's a thousand?" Xie Erdun hurriedly said.”
I didn't learn it!
"Alright, sit down!"
Yan Bugui asked Xie Erdun to sit down and asked a few other students.
The more he asked, the darker his face became.
He realized that the students were quite familiar with the conversion between meters, kilograms, kilograms, centimeters, and meters.
However, once it involved square meters, square centimeters, and square decimeters, it would not work.
It was always wrong.
It was either too much or too little!
What was going on? They were all memorizing things. Could it be that they couldn't memorize them?
"Ye Fan... tell me..."
Yan Bugui looked at Ye Fan,"One square meter, how many square centimeters is that?"”
"100!" Ye Fan said.
"How many square centimeters is one square centimeter?”
"A hundred!"
"How many square centimeters is one square meter?”
"Ten thousand!"
"Then…how many cubic centimeters is one cubic meter?”
"One million!"
"Hiss hiss…"
Yan Bugui took two deep breaths and said,""Eh... Ye Fan... Others can't remember it, but why do you remember it clearly?”
Ye Fan smiled bitterly and spread his hands.
" Mind how you address me…" Yan Bugui slapped the table,""In school, you call me Teacher Yan.”
" Alright, alright..." Ye Fan said,""Actually, this is too complicated. I can't remember it either. One moment it was meters, the next moment it was square, the next moment it was cubic…It's too roundabout…"
" Then…" Yan Bugui asked," How did you come back to the correct one? Did you just guess?"”
" Of course not...""I calculated it."
"Ah…You can even calculate the unit conversion?”
Yan Bugui began to doubt his life.
One meter was equal to 100 centimeters!
One square meter was equivalent to ten thousand square centimeters!
Wasn't this all memorized?
He could even calculate it?
Bullshit!
In the early days of the founding of the People's Republic of China, the teachers 'educational level was not high, especially in terms of mathematics. They did not have the spirit of striving for excellence at all.
Besides!
The school lacked a math teacher the most. Yan Fugui was originally teaching the children Chinese, but he had no choice but to be pulled over to teach them arithmetic.
His knowledge was limited.
"Sure…" Ye Fan said.
" Alright then…" Yan Bugui said," Come up here and read my fortune…"
Ye Fan did not hesitate at all and walked up to the podium generously.
He picked up the chalk and said,"Let me calculate the conversion ratio between this square meter and square centimeter!"”
Yan Bugui nodded.
Ye Fan drew a square.
"Is one meter equal to one hundred centimeters?”Ye Fan asked Yan Fugui.
"Yeah…" Yan Bugui nodded.
"Then…is one square meter equal to one meter multiplied by one meter?”
"Yes…" Yan Bugui nodded again.
" That's good..." Ye Fan said,""Look, one square meter is equal to one meter multiplied by one meter, and one meter is equal to 100 centimeters. Then, one square meter is equal to 100 centimeters multiplied by 100 centimeters.”
Boom...
Yan Bugui's body trembled,'That's right…10,000.'
It turned out that he could really calculate it.
This…
Good heavens…
This child was really smart.
He didn't notice it before. Could it be that he had been enlightened?
Yes, yes, yes…
He must have reached the age where he suddenly became enlightened!
