Chapter 23: Overestimating One's Own Strength!
"Unbelievable... Teacher, your expression seems to be saying 'Your Highness is right'!"
"Wow! Is Your Highness a child prodigy? I'm so in awe!"
"Quiet! Don't count if you're wrong!"
"Cut! How can you be like this, teacher?!"
With a cold smile, he continued: "a3 and a10 are the two real roots of the quadratic equation x^2 - 3x - 5 = 0, so a3 + a10 = -b/a = 3. In an arithmetic sequence, a3 + a10 = a5 + a8, therefore: a5 + a8 = 3. Since a10 is one of the real roots of the quadratic equation x^2 - 3x - 5 = 0, we have c/a = -5, which yields the result 7 = -5."
Classmates discussed it in an uproar:
"I don't understand..."
"It's just that it sounds very impressive and easy to calculate! I've calculated the first term and common difference of the sequence, and my head is already spinning!"
"Wow... Your Highness is really a child prodigy! So clever!"
The math teacher looked at the textbook in shock, then looked at him. How is this possible! He actually calculated this question easily with another method!
"How... how is this possible! How could you have calculated it?!"
He didn't believe it and came up with a few university-level math problems, which I answered one by one correctly, explaining the process in great detail.
In the end, everyone's expression turned into——
My goodness! How is that possible? He didn't use a pen or paper, and his brain didn't even turn around, yet he was able to say it quickly, fiercely, and accurately!
"No... it's impossible! How can you possibly do it!"
The math teacher was no longer calm, and he rushed towards Yu in a flurry. He looked like he wanted to tear Yu into eight pieces.
"Ah! Your Highness!"
With a gentle and careless tone, with just a slight lift of his hand, one finger pressed against the teacher's chest, he was unable to move!
Everyone was stunned, and by the time they reacted, the teacher had already been beaten several meters away...
He turned his gaze back and snorted: "You're overestimating yourself!"
