On the playground not far away, there are many students gathered together, and there is a high platform built in the middle, which seems very lively.
Xue Xueer is curious.
She went over to have a look and found that it was a mathematics competition spontaneously established by the student union. Even the test questions were discussed by the top students of the mathematics department.
There are also two groups of people participating in the competition, three in each group.
"The quality of the topic is good."
Xue Xueer looked and whispered.
A female college student beside her just heard this and smiled at her kindly.
"Of course, this is the problem designed by our professor, but these students changed the variables in the problem, and the numbers were different, so the problem changed."
i see.
Xue Xueer nodded slightly and continued to look at the participants.
In these few minutes, several students in the competition have calculated the answers, wrote the final results on the small board and held them up.
The answers of the two groups are the same.
Seeing the result, Xue Xueer frowned slightly, but said nothing.
The host has announced on the platform.
"The answers of the two groups are the same. They are all correct answers. It seems that our math competition will end in a tie."
"No!"
The voice of opposition suddenly came out of the crowd. It was the female student who had just spoken to Xue Xueer.
Her voice was sharp, and many students, including the host, looked at her. The host's eyes were a little bad and raised his tone.
"This classmate, what's wrong with you?"
"Your calculation is wrong."
The female student seemed a little timid, but she took a deep breath, summoned up her courage and said, "both of your groups ignored the first variable in the calculation. If you calculate it in advance, the result will be one."
Everyone's eyes have changed.
Both groups of students got the answer, which was zero.
Should I trust her or most people?
The host chose the latter without hesitation.
"This classmate, I'm sorry. The people in our math group also calculated accurately before the competition. The answer to this problem is zero, not one. You made a mistake."
The voice fell to the ground, and other people watching the game talked with it one after another.
"I just calculated it. It's zero."
"Yes, I'm zero. I think she wanted to be in the limelight, so she deliberately made such a noise at the end of the game to let everyone pay attention to her."
"All the students participating in the competition are top students in the Department of mathematics. They are recognized as the top few in the grade. If she is really famous, why can't she participate in the competition?"
"It was deliberately eye-catching."
Everyone's voice was not low. The female classmate didn't expect to be targeted by everyone. Her face turned red when she was heavy.
"What I said is true. It's one, not zero."
She wanted to go on stage, pointing to the ignored variable symbols and trying to make it clear, but the host didn't give her a chance and announced that the result was zero.
Seeing that everyone's eyes were not very kind, the female student was very worried and her tears fell down.
Why doesn't anyone believe her?
Xue Xueer was touched to see her cry and feel wronged.
If she was accused by most people, I'm afraid she couldn't resist this pressure.
She needs help.
Some people are still saying sarcastic words: "can everyone listen to you when you cry? In the world of mathematics, right is right and wrong is wrong. Don't pretend to be poor."
"That's enough. You're all wrong."
Xue Xueer couldn't bear it any longer. She came forward to interrupt her and looked at the schoolgirl.
"Your calculation of this question is wrong. The correct answer is one. Pay attention to this symbol."
Xue Xueer stepped onto the platform and circled the calculation symbols that were the first and most easily ignored.
With her movements, the faces of the students in the two participating groups were dignified.
Two people pointed out this symbol one after another, and they both doubted themselves.
Is it really a miscalculation?
Just then, the voice of doubt came from the crowd.
"Who are you? I've never seen you before. Why should I believe you?"
