„You heard certainly the answer that I said a moment ago, or before is you, has seen this issue!” Li Xuan was startled a moment later, immediately incomparably affirmative saying. “你一定是刚才听到我说的答案了,或者是你之前见过这道问题！”李轩怔了片刻之后,立刻无比肯定的说道。 If Li Yi after this burns a joss stick even burnt a joss stick within gave the answer, although he will also feel the surprise, but also in his bearing capacity. 如果李易在这一炷香之后甚至一炷香之内给出了答案,他虽然也会觉得诧异,但也在他的承受能力之内。 After all in his eyes, Li Yi, even if not the Jing State first smart person, but still differs not far. 毕竟在他眼中,李易就算不是景国第一聪明人,但也相差不远。 But he just said the issue, Li Yi can give an oral account the correct answer, this is not a person, is the monster. 而他刚刚说完问题,李易就能一口说出正确的答案,这不是人,是妖。 This time, Li Xuan also really guessed mistakenly, a moment ago his suddenly hysteria jumped, frightened Li Yi to jump, where had the thoughts to listen to this goods mouth to say anything. 这一次,李轩还真的猜错了,刚才他忽然癔症似的跳起来,吓了李易一跳,哪有心思去听这货嘴里到底说了什么。 But before has seen similar issue, but trades a number, the answer is also different, does not have the second possibility that he said. 而之前虽然见过类似问题,但换一个数字,答案也不一样,并不存在他说的第二个可能。 Issue of chicken rabbit with cage, in later generation, so long as perhaps has studied the elementary student of Mathematical Olympiad, can send out the answer, does not use the method that selects to cheat completely. 鸡兔同笼的问题,在后世,恐怕只要是学过奥数的小学生,都能一口报出答案,完全不用采用作弊的方式。 Tests itself with this elementary school difficulty topic, isn't this brings contempt upon oneself? 用这种小学难度的题来考自己,这不是自取其辱吗？ „Hehe, you , to repudiate a debt speaks frankly, why to find this excuse.” Li Yi curls the lip, visits him, saying that quite disdains. “呵呵,你要是想赖账就直说,何必找这种借口。”李易撇了撇嘴,看着他,颇为不屑的说道。 Red that a handsome face of Li Xuan rises, solemn Heir Apparent, the matter of repudiating a debt said that is not quite indeed of pleasant to hear, but he actually more urgent wants to know, Li Yi gets that answer with what method. 李轩的一张俊脸涨的通红,堂堂世子,赖账的事说出去的确不太好听,不过他却更迫切的想知道,李易到底是用什么方法得到那个答案的。 „How so long as you told me you to solve this topic, except for reaching an agreement that beside 120, I lost you again 120.” Money regarding Li Xuan is only a number, what he is interested being Li Yi ejects these novel methods of each time. “只要你告诉我你是如何解出此题的,除了说好的那一百两之外,我再输你一百两。”钱对于李轩来说只是一个数字,他更感兴趣的是李易每次抛出的那些新奇方法。 The Li Mingzhu vision also placed on Li Yi, this problem, she is also knows it however not to know its reason why, tries, on the flower 1 time, naturally can try the answer, but he can that quick figuring out, if not know the answer beforehand, uses them not to see the method. 就连李明珠的目光也放在了李易身上,这道题,她也是知其然不知其所以然,一个个的去试,花上一点时间,自然能试出答案,但他能那么快的算出,如果不是事先知道答案,就是用了一种她们都没有见过的方法。 Money to Li Xuan is only a number, but to Li Yi, that is not the brick of big house, a piece of tile, a room...... 钱对李轩来说只是一个数字,但对李易不是啊,那可是大宅子的一块砖,一片瓦,一间屋子啊…… „You said a moment ago ------ On has 35 heads, does below have 94 feet?” His opens the mouth , indicating that tacitly approves action that Li Xuan gave money a moment ago. “你刚才说------上有三十五头,下有九十四足？”他的开口,表示默认了李轩刚才送钱的举动。 Li Xuan nods again and again. 李轩连连点头。 „We assumed, but the supposition......” Li Yi put out a hand to gesticulate, „supposed that these chickens and rabbits were well-trained.” “我们假设,只是假设啊……”李易伸手比划了一下,“假设这些鸡和兔子都训练有素。” A Li Xuan face compels ignorant, the problem solving on the problem solving, what relations has with these chicken rabbits well-trained? 李轩一脸懵逼,解题就解题,和这些鸡兔是不是训练有素有什么关系？ However, in view of the fact that Li Yi always does not take the common road, he thought first listens. 不过,鉴于李易一向都不走寻常路,他还是觉得先听下去。 Li Mingzhu hearing this knits the brows, quick loosening, obviously also and Li Xuan has the similar idea. 李明珠闻言皱了皱眉,又很快的松开,显然也和李轩有着同样的想法。 „If these chicken rabbits are very obedient, pats starts, they will then lift a foot......” “如果这些鸡兔都十分听话,拍一下手,他们便会抬起一只脚……” „How can there be so solution?” The Li Xuan hear, where had such obedient chicken and rabbit, passing that if such strange method can also say, that made these chicken rabbit mouths spit the criticism/human language simply, oneself said the similar number to consider as finished. “焉有如此解法？”李轩听不下去了,哪里有这么听话的鸡和兔子,如果这么离奇的方法也能说的通,那干脆让那些鸡兔口吐人言,自己说出同类的数目算了。 Li Yi stared his one eyes, „also wants to know the method?” 李易瞪了他一眼,“还想不想知道方法了？” „You, if talked nonsense like again, money may not have.” Although Li Xuan is silly, but does not have to that degree stupidly. “你要是再像这样胡说八道,银子可就没有了。”李轩虽然傻,但也没有傻到那个程度。 „Continued.” Li Mingzhu as if understood anything, eye, urged. “继续说下去。”李明珠似乎明白了什么,目露奇芒,催促道。 Li Yi looked at Li Xuan one with the complex look, Li Xuan understood his meaning. 李易用复杂的眼神看了李轩一眼,李轩读懂了他的意思。 He was ridiculing oneself were inferior to Mingzhu/Pearl. 他是在嘲笑自己连明珠都不如。 However, Mingzhu/Pearl was intelligent since childhood, when the youth and he accepts in the palace together the mister taught, Li Xuan discovered this matter. 不过,明珠自幼聪颖,少时和他在宫里一同接受先生教导之时,李轩就发现了这件事情。 Although this is the indisputable fact, but at heart, how to be uncomfortable? 虽然这是不争的事实,但心里,怎么就那么不是滋味呢？ „Pats palm a time, lifts 35 legs, pats holds twice, lifts 70 legs, at this time, all chicklings sit in the cage , without the leg may count, each rabbit remaining two legs, in cage legs 20 and four, then rabbit dozens two, chicken several 23.” “拍一次掌,共抬起三十五条腿,拍两次掌,共抬起七十条腿,此时,所有的雏鸡坐于笼中,无腿可数,每只兔子剩下两条腿,笼中余腿二十又四,则兔数十二,鸡数二十三。” As opening the mouth of slowly Li Yi, in the Li Mingzhu eye greatly hold, Li Xuan is dumbfounded. 随着李易的缓缓开口,李明珠眼中奇芒大盛,李轩则是目瞪口呆。 At this moment, perhaps only then goes full steam ahead to describe the true feeling in his heart. 此刻,恐怕只有万马奔腾才能形容他心中的真实感受。 This his mother also? 这他娘也可以？ Puzzled he entire day of issue, unexpectedly only with patting holds twice can solve? 困扰了他整整一天的问题,居然只用拍两次掌就能解决？ That old fogey did not say yesterday? 那老匹夫昨天可不是这么说的啊？ Said that what this is the difficult problem that spreads from ancient, even if cannot solve not to relate, because master also only know the answer, does not know the concrete solution. 说什么这是从古流传的难题,就算是解不出来也没关系,因为夫子自己也只知道答案,不知道具体的解法。 He then looked at Li Yi one ------ Really is the monster! 他回头看了李易一眼------果然是妖啊！ Li Xuan expression Li Yi all watches, regarding this not many surprise. 李轩的表情李易全都看在眼里,对此并没有多少诧异。 This world does not have the Arabic numerals , without the dual first power regulation, the math together, only to be called as at best is the arithmetic, but also at the ignorant stage, several hundred years may emit a going against heaven's will mathematician, status or astronomer or taoist priest...... 这个世界没有阿拉伯数字,没有二元一次方程,数学一道,充其量只能称作是算学,还处在蒙昧的阶段,几百年可能才会冒出一个逆天的数学大师,身份还是天文学家或者道士…… After all the imperial civil service examination test does not test these, the arithmetic well-respected degree is not high, issue of a chicken rabbit with cage, perplexing Imperial College Arithmetic Court Academician is not the unusual matter. 毕竟科举考试又不考这些,算学受重视程度也不高,一个鸡兔同笼的问题,难住国子监算学博士也不是什么稀奇事。 Method that he used a moment ago, named „raising legs law”, is not the piece that in the later generation network Botswanan people smile, in the ancient times arithmetic classics «Sun Tzu», indeed solved this topic like this. 他刚才所用的方法,名为“抬腿法”,不是后世网络上博人一笑的段子,古代算学经典《孙子算经》中,的确就是这样解此题的。 Can infer from the response of Li Xuan and Li Mingzhu, «Sun Tzu» does not exist in this world either, is the age is too either long, this problem solving method was lost. 从李轩和李明珠的反应中可以推断出来,《孙子算经》要么并不存在于这个世界,要么就是年代太久,这种解题方法失传了。 „Has such problem solving method unexpectedly, is really unthinkable.” Li Xuan acclaimed said. “竟有如此的解题方法,实在是匪夷所思。”李轩不由的赞叹说道。 He is actually not thick regarding the arithmetic interest, but is thinking solves this problem, lets teach his master to hold in high esteem, thinks entire day, right key in mind experimental, again with Li Yi this trying another method method, only the time that uses two to breathe. 他对于算学其实兴趣并不浓,只是想着解出这道题,让教他的夫子刮目相看而已,想了整整一天,才将正确答案在脑海中试了出来,再用李易这种另辟蹊径的方法,只用了两个呼吸的时间。 „Unthinkable, doesn't matter, we can try another method.” Li Yi is very sincere, at least needs to make Li Xuan feel value that these two hundred taels of silver lose. “匪夷所思是吧,没关系,我们可以试试另一种方法。”李易还是十分厚道的,至少要让李轩觉得这两百两银子输的值。 „Unexpectedly other methods?” Li Xuan exclaimed in surprise one, the head collected. “居然还有其他的方法？”李轩惊叹一句,脑袋凑了过来。 „First, you need to remember new methods of attributes......” “首先,你们需要记住一种新的计数方法……” Li Mingzhu and Li Xuan look that Li Yi writes to draw on the xuan paper with, these strange simple graphs, are they have never seen, combines, unexpectedly is new methods of attributes. 李明珠和李轩看着李易用笔在宣纸上写写画画,那些奇怪的简单图形,都是他们从未见过的,组合起来,竟是一种新的计数方法。 Two people are accept the aristocrat to educate, the foundation is solid, although this thing is seemingly novel, but is not difficult to understand, after the simple explanation of Li Yi, spent the little time, then generally digests this set of rule. 两人都是接受过贵族教育的,底蕴深厚,这东西虽然看起来新奇,但不难理解,经过李易的简单讲解之后,花了少许时间,便将这一套规律大抵消化。 In the heart expressed admiration, this method, without doubt be better on many than the Jing State present methods of attributes, convenience simple...... 心中啧啧称奇,这一套方法,无疑是要比景国如今的计数方法要好上许多,更加的方便简单…… „This named equal sign, this is the plus sign, the minus, this fork fork, can understand that...... Li Yi has not thought so many for the number that has not known temporarily” at first, starts to explain truly time, discovered that gives them to spread these knowledge, compared with not teaching two just got up the child of elementary school to want easy many. “这个叫等号,这是加号,减号,这个叉叉,可以理解为暂时还不知道的数……”李易最初没有想那么多,真正开始讲解的时候,才发现给他们普及这些知识,不比教两个刚上小学的孩童要容易多少。 But the words have said that naturally cannot give up halfway, has to bear the temper, prompting forward bit by bit. 但话都已经说出口了,自然不能半途而废,只好耐着性子,一点一点的向前推进。 After half double-hour . 半个时辰之后。 „This, comes out two unknown solutions, was the number of chicken and rabbit.” Li Yi long breathing a sigh of relief, gave them to popularize finally from beginning to end, quite somewhat exhausted feeling. “就这样,将两个未知数解出来,就是鸡和兔子的数目了。”李易长长的舒了一口气,总算从头到尾的给他们普及了一遍,颇有些心力交瘁的感觉。 Teaches bear the child to be simple, makes up a story to deceive casually, if later Li Xuan asked again this issue, does not add money is not absolutely dry! 还是教熊孩子简单啊,随便编点故事就能糊弄过去,以后李轩要是再问这种问题,不加钱绝对不干！ „Understood?” He visits two people, asking of anticipation. “懂了吗？”他看着两人,期待的问道。 Although process winding a point, but if they understood, at heart is also a little small comfort. 虽然过程曲折了一点,但如果他们听懂了,心里也算是有点小小的安慰。 „No.” Li Xuan is categorical, does not have slightly hesitant saying. “没有。”李轩斩钉截铁,没有丝毫犹豫的说道。 The Li Mingzhu same eye of reveal has doubts. 李明珠同样的目露疑惑。 „Two rotten wood” in the Li Yi heart sigh deeply. “两根朽木”李易心中长叹。 „Xiao Huan, sees a visitor out!” “小环,送客！” Looks young housemaid who gets to the entrance, Li Yi decisive opens the mouth. 看着走到门口的小丫鬟,李易果断开口。 „Young Master, ate meal......” young housemaid to stand in the entrance, weak saying. “姑爷,吃饭了……”小丫鬟站在门口,弱弱的说道。 „Isn't anxious, first ate meal, waits to finish eating the food, you spoke several to me to understand again.” Li Xuan patted his shoulder, stands, smiling is looking at the young housemaid, asked: „Xiao Huan does Young Lady, where eat meal?” “不急不急,先吃饭,等吃完饭,你再给我讲几遍就应该就懂了。”李轩拍了拍他的肩膀,站起来,一脸笑意的望着小丫鬟,问道:“小环姑娘,在哪里吃饭？”
