In the world of math, many strange results are possible when we change the rules.
Normally,dividing by smaller and smaller numbers gives you bigger and bigger results.For example,Twenty divided by two is ten,twenty divided by ten is two.Imagine you have twenty dollars and you need to give unknown people,so if the numbers become big, then the average amount will be less.
Try to understand what is the division really means.?Twenty divided by two could mean "How many times must we add two together to the twenty",yeah,the answer is ten times.
so I want to ask you question,How many times must we add zero together to the twenty?
Besides,Dividing by a number is essentially the revere of multiplying by it.You know twenty divided by two is ten ,so the ten can multiply two become twenty,but the zero multiply any number is still zero,So if you choose zero as division, the answer is impossible to speak.
The division means the average,so if you divide by numbers that keep shrinking all the way down to zero,the answer will grow to the largest thing possible.When you enter to the college class,you can see the symbol of infinity.
Fallacy: 0*1=0;0*2=0 ;0*1=0*2=0; 0/0*1=0/0*2
Look,pay attention to what you get,1=?=2! That's already break the rules,it is a ridiculous resolution!
Finally,if you ask siri about the problem that"why not zero become division",you will get the follow answer:
You have the twenty cookies , and you split them evenly among the zero friends, how many cookies does each person get??
See! It doesn't make sense ,cookies will be sad because that there are no cookies,you will be sad because you have no friends.
這是昨天在英文巴士上聽到的一篇外文推送,恰逢自己在跑步漓概,于是邊跑邊思考這個問題,以前老師總是告訴我們0一定不可以作除數(shù)哨苛,卻沒有告訴我們?yōu)槭裁矗绻腥烁信d趣的話也可以去維基百科上去搜索相關(guān)內(nèi)容或者用英文問一下你的siri為什么0不可以作除數(shù)爱沟,你都可以得到一個意想不到的答案。
自己用中文梳理一下這個問題的答案吧塞栅。最通俗的一種解釋就是准潭,除數(shù)作為一種平均的意義趁俊,就像分餅干,分給0個人刑然,我怎么都分不出來啊寺擂,所以無解。第二種解釋就是泼掠,除法作為乘法的逆運算怔软,你要知道任何數(shù)(無窮無盡的數(shù)字)*0=0,而择镇?*0=6這個等式是不存在的挡逼,所以0不能作為除數(shù)。第三種解釋就是想象一下你一共有1元錢腻豌,請問你想從0元開始起步家坎,那么需要多少個0相加才能得到1元呢,也許讓時間無限延續(xù)下去饲梭,你真的可以得到這1元乘盖,但是這個0就好像是一場夢(不存在的),只要你不醒憔涉,你永遠(yuǎn)無法踏出這一步,你也終究是個異性人不存在的析苫!
