[The length of a rectangular tabletop is 370 centimeters and the width is 9 decimeters. What is the circumference of this tabletop in decimeters?]
"92 decimeters." Lin Jiayi just glanced at it and answered directly without even picking up the pen.
The time between reading the question and answering the question should not exceed three seconds.
Everyone's eyes suddenly turned to the teacher.
They all seemed to be waiting to hear the teacher's answer.
A trace of surprise flashed in the teacher's eyes, and he adjusted another question: "What about this one?"
"1320 meters." The answer was faster than the previous question.
"This way?"
"3 decimeters."
"."
The math teacher asked five questions in a row and she answered the questions at a glance.
The classmates in the class didn't know whether she was right, but the audience in the live broadcast room were not third-year students, so they naturally knew whether her answer was correct.
[Don’t ask, baby Jiajia’s answers are all correct! I guarantee it with a score of 635 in the college entrance examination!]
[Can you believe it? I am not as fast as a seven-year-old child in mental arithmetic. I am autistic.]
[I’m more autistic than you. Before I even finished reading the questions, baby Jiajia’s answer came out. Who said yesterday that our baby Jiajia wouldn’t be able to understand the third-grade curriculum? Stand up for me!]
The teacher didn't give up, so he directly found a third-grade math Olympiad problem and gave it to her: "What about this one?"
[36 people want to cross the river, and the boat can accommodate 6 people. How many times will it take for them all to cross the river? 】
Lin Jiayi looked at the topic again, sighed, and glanced sideways at Song Siqi, finding that she had raised her head and stared at her sleepily.
The classroom was quiet, everyone was waiting for her answer.
Just when the teacher thought this question stumped Lin Jiayi, she finally spoke.
"7 times."
The teacher's eyes were stunned, and he paused for a few seconds before speaking: "Correct."
"Wow"
There was a burst of sighs in the class.
【Huh? 7 times? Not 6 times?】
[Upstairs, open your eyes and see clearly, the Mathematical Olympiad question, if it is so simple, can it be included in the Mathematical Olympiad question? 】
[Hahahaha! It’s over, the above has been exposed, it’s worse than a seven-year-old child!]
[So am I the only one who realizes that baby Jiajia seems a little too smart? 】
The teacher recovered from the shock and thought she had been fooled casually, so he asked: "Why 7 times?"
"Because every time the boat goes to the other side, one person has to row the boat back. Only the last trip is when all 6 people cross the river, so 36 minus the 6 people in the last trip equals 30. Only 5 people can cross each trip because
To have one person left to paddle back is 30 divided by 5 which is 6 plus the last trip, so the answer is 7."
Thinking clearly and logically.
Now the teacher had to believe that she really knew how to do it.
"That's right. Jiayi can sit down now."
The teacher couldn't help but look at her twice before turning back the PPT.
I couldn't stop being amazed.
Are these really uneducated children from rural areas?
This is too smart!
[Oh my God! Baby Jiajia’s IQ seems to be a bit high! Her thinking is also very flexible! It’s amazing!]
[I originally thought that baby Jiajia was just a child with an appearance, but I didn’t expect that her IQ was so high! 】
[It feels like a smaller version of the heroine of a heroine with a super high IQ! She is beautiful, strong and smart!]
When the classmates looked at Lin Jiayi, they looked less contemptuous and disdainful, and more curious and appreciative.
Song Siqi still glanced at her with disdain and continued to lie down to sleep.
Lin Jiayi sat down obediently, rested her chin on one hand and continued to stare out the window in a daze.
Jiang Shixin, who was sitting at the front table, quietly turned his head and widened his eyes: "Boss, are you really from the countryside?"
The voice he yelled was neither too loud nor too quiet, and could just be heard by the people around him.
The boy who was their referee was sitting on the right side of Jiang Shixin. Hearing this sound, the boss couldn't help but turned around and laughed at him: "Jiang Shixin, I must have become familiar with this status too quickly."
Jiang Shixin glared at him angrily and continued to look at her.
Lin Jiayi thought for a while and nodded with sincere eyes: "Really."
She did come from the countryside at that time.
Good children don't lie.
"Then who did you learn mathematics from?" Jiang Shixin continued to ask.
"Brother." Lin Jiayi didn't hide anything.
She did learn math at the beginning from her brother.
"Do you have a brother?" The boy next to her also turned to her curiously and asked.
Most of the people in the class are only children, and there are very few families like the Song family with a son and a daughter, so they actually envy people who have an older brother, sister, and younger brother and sister at home.
This way at least two people at home won't be bored.
When talking about his brother, Lin Jiayi's eyes became full of admiration: "Well, my brother is super powerful! He is the target I want to catch up with!"
As he spoke, Lin Jiayi's emotions became obviously excited, and his eyes shone with admiration and passion.
[I have begun to wonder who Jiajia’s brother is. This is the first time I have seen Jiajia showing such an uncool look since the show started.]
[Indeed, she is not very calm like a child on weekdays, but now I feel that she is much more agile. 】
[Hahaha! I don’t know if Jiajia’s brother is watching the live broadcast now. Will he be shy after hearing Jiajia’s words? 】
[I’m so envious of Jiajia baby’s brother for having such a well-behaved, smart and beautiful sister like Jiajia baby!]
Jiang Shixin and the boy were both stunned.
They just asked casually, but they didn't expect Lin Jiayi to be so excited.
But in their subconscious mind.
How powerful can people from rural areas be?
The two of them wanted to ask more questions, but were interrupted by a piece of chalk flying over from the podium.
"Jiang Shixin, Jiang Ye! Why do you two keep turning your heads back? Do you already understand, so you don't need to listen to the lecture?"
Hearing the teacher's roar, the two of them turned their heads back in despair.
After all, this teacher is none other than Jiang Shixin's aunt.
Picking them up is a piece of cake.
Finally, when get out of class was over, the teacher was tidying up the textbooks on the table and urging the class representatives of each subject to collect their summer homework.
Lin Jiayi looked in the direction of Song Siqi and looked away after seeing that she had indeed handed in her summer homework.
As soon as the teacher left, many girls gathered around Lin Jiayi and asked her questions.
"Classmate Jiayi, where is your home?"
"Jiayi, your math is very good! Who taught you?"
"Jiayi, do you want to come to my house after school? I went to country Z with my mother during the summer vacation and brought back chocolates from there. They are delicious!"
