Chapter 51 (2/2)
“The final question! I don’t understand the logic behind it” After pulling the math teacher to his classroom’s lectern, Chen Yu ran to his seat and pulled out his mathematics test paper He then ran back to the lectern, placed the paper before the teacher, and pointed at the last question, saying, “It’s this one I don’t understand it”
“Oh, this question” The ht How should I solve it? What’s the concept behind it?”
“This question…” After studying the question for a while, the ed and said, “I don’t know, either”
“?”
“It’s too difficult None of the teachers in the school kno to solve it”
“Then, why did you even put this question in there?!” Chen Yu bellowed
“It’s because we don’t kno to solve it that we put it in there,” thehis head, he continued, “We wanted to see if there were any students that kne to solve it Unfortunately, we found out that the students didn’t know, either”
Chen Yu: “…”
“Student Chen Yu, don’t look at me like that There are no perfect humans Even Einstein had probleht? You shouldn’t impose your opinions on others”
“Do you think you sound very logical?”
“In any case, I don’t kno to solve it,” theup his chest proudly, he continued, “On what basis ive out? Aren’t the mathematics world’s three major conjectures unsolvable as well?”
Chen Yu: “…”
“I don’t know”
“…Fine Fine, fine, fine” Breathing out a deep sigh, Chen Yu nodded and pointed to the second most difficult problem in the test paper and asked, “What about this one? It’s very difficult, as well I can’t grasp the concept behind it”
“This question?” After taking a serious look at the question, the math teacher said, “I don’t know”
“You dah’s top student ed to answer it, yet you don’t kno?”
“Then, if there are students that kno to dance, why don’t you kno to dance too?”
“Are these two things even related to each other?!”
“In any case, I don’t kno to answer that question”
“Fine, fine, fine You win” After flipping to another page, Chen Yu pointed at a fill-in-the-blank question and asked, “What about this one?”
“Don’t know”
“This?”
“I don’t know that, either”
“This…”
“Oh, I don’t know that, either”
After a moment of silence, Chen Yu asked, “Then, do you knohat’s 1+1?”
At Chen Yu’s question, the rabbed a piece of chalk and started frenziedly writing formulas on the blackboard!
[i) 0 is a natural number; ii) Every determined natural number a would have a successor number x’ x’ is also a natural number; iii) if b and c are both a‘s successor numbers, then b= c; iv) 0 is not a successor number of any natural number; v) Let S be a subset of the set of natural nus to S, then n’ also belongs to S]
[…x is not in the range of f; f is an injective; if x ∈ A and “a ∈ A implies f(a) ∈ A,” then A = x…]
[…N (Natural Number Set) is not an e from N to N…]
[…If the subset P of N contains both non-successive ele each element in the subset, then this subset is equal to N…]
[1+1 proves that:
∵ The successor number of 1+1 is a successor number of 1, which is 3,
∴ The successor of 2 is 3
According to Peano axioaze, theup the entire blackboard with for his shoulders, the math teacher finally wrote a number after the “=” symbol
[1+1 = 13,627]
Finally, Chen Yu’s mouth fell wide open
