That's true, but Japanese is similar to Chinese, just that while the words are pronounced differently, the only thing that Japanese and Chinese have in common is that one particular writing system, the Japanese Kanji system, although pronounced differently, they have nearly the same characters as the Chinese Hanzi system. And yes, you might see some Chinese characters that are not kanji, and that some Japanese kanji are invented, not from the Chinese Hanzi system. Some Chinese characters are similar to kanji, but some are written in a different way, so yes, Chinese is different from Japanese, but they're similar to just the writing systems. You will see most of the kanji to be same as the Chinese characters, that's one of the reasons why it's recommended to start from Japanese, and then learn Chinese.
Is it true that a÷bc=ac÷b ? I am confused with the problem 6÷2(1+2). According to our current textbook and my scientific calculator, it is 1. But Google says, it is 9. Can you please tell me?
Here's my attempt at "proving" ÷0 is a bad idea: Observe that 0 × Z where Z is on the complex plane always yields 0. n ÷ 0 is therefore not on the complex plane. Replace the complex plane with any number space where the observation holds, and we can quickly prove that n ÷ 0 doesn't work in most number spaces.
除以零 (從幼稚園到研究所)

How much maths to speak this language
我喜歡這段影片😘有實際具體的演算可以解釋為何不能除以零，有瞬間頓悟的感覺
我赞同，不喜欢“就是不能除以0啊”，喜欢解释和理解的教法。
在此分享第三种解释方法：分母和分子是一样的数字的话（比如3分之3）就是1，但是只有0分之0不等于1，所以分母不能是0。
网络上很多证明0＝1or1＝2的影片，其中的错误就是不能约掉未知数，因为可能是0。
Isn’t RUclips blocked in China?

did you do this
博主老师，您所说的“长大后，越来越懂事后”指的是在大学学了高等代数之后，学习了如何证明“在代数运算中，只有0不能做被除数”，才解开了这个小时候令你伤心的疑惑吗？因为我是一个普通的大一新生（才刚开始学高等代数），还没有办法真真实实的去解开这个也令我非常在意的疑惑，我很想知道您的回答，很想知道关于这一证明是否会在我的大学时期得到严谨的证明（我的专业是应用统计学）。
正解，除法是乘法的逆运算。找不到一个数和0相乘等于7.老师用这个做对比很直观，更容易理解。
你就先assume。。 你就要去。。。assume xd
太好笑 太可愛了！
你的學生一定都很幸福。@@
還真希望你是我老師呢！
anyway 很喜歡你的片！ ^^
0 X8 =0 X2 ------
--- --- 0
0 0 ------
原因是因為0×8等於零， 0×2等於0 ，然後兩個都是一樣的因為這樣就變成0／0
曹老师好！下个video可不可以解释怎么证明:
如果 x_1, x_2, x_3, x_4, x_5 & x_6 都是 positive real number, 那
(x_2/x_1)^5 + (x_4/x_2) + (x_6/x_3) + (x_1/x_4) + (x_3/x_5) + (x_5/x_6) ≥ (x_1/x_2) + (x_2/x_4) + (x_3/x_6) + (x_4/x_1) + (x_5/x_3) + (x_6/x_5)
谢谢您曹老师! 我名叫刘佶沅，来自新加坡，所以我不用繁体中文字，对不起。我13岁，但是因为您的videos, 我已经学会了围分与积分，谢谢!♡
Where is eng subtitles. Oh sry you were not using subtitles in any video.
I have this in Eng already. See description : )

If you speak Japanese, you might understand Chinese a bit easier!
Einstein Gonzalez Chinese language is not equal to Japanese

感謝老師分享 淺顯易懂 好讚阿
用零除以零等于几呢？
You can prove with limits combined with graph that dividing with 0 will result in +- infinity.
我从你的视频学习中文...
只是开玩笑，它是谷歌翻译
I understand every single word you say, just trust me
I watched this video even though I barely know any chinese. I still understood what he was saying through the math on the board.
分母0是奇點,要挖掉或給某個定義(有界?)不然沒法算
老师老师，为啥0不能除以0呢XD
第二个解释我更喜欢 :3 更严谨。我也帮你写了英语字幕请看看！如果翻译的不正确的话，让我提前抱歉；汉语不是我母语。
講的好 用各種方法講解瞬間頓悟

Is it true that a÷bc=ac÷b ?
I am confused with the problem 6÷2(1+2).
According to our current textbook and my scientific calculator, it is 1. But Google says, it is 9. Can you please tell me?
Because calculator used postfix expression, but Google uses general arithmetic expression calculation
Hi can u solve e^x=sinx without drawing a graph and finding x value
Lee Dywei There are no elementary functions through which you can isolate x. So really the best bet is to use the graph

老师我有个问题，2:10 如果是0➗0，用如图的直式，多少乘0会等于0呢？答案是0。可以诶？那不是可以0➗0了吗
但是其實1也可以
1乘0會等於0
2乘0會等於0
-100乘0會等於0
√31乘0會等於0
π乘0會等於0
所以你會發現其實所有數字都是0÷0的答案，但這就是問題所在了。
在之前那些35÷7和7÷5，我們只有一個答案，但是對於0÷0卻有無限多個答案，這豈不是另一個更嚴重的問題嗎？
@@2070user 那甚麼時候0除以0會成立呢?
@@張舜祺 當取極限時，0÷0便有「新的意義」
如lim x→0 (x/x) = 1
則0÷0「等於」1
又如lim x→0 (10x/x) = 10
則0÷0「等於」10
可見儘管在取極限，0÷0依然有無限多的答案
但至少0÷0在取極限時有「更嚴謹」的定義
@@2070user 0*8=0*2 甚麼時候可以把0拿掉
@@張舜祺 這個例子就不行了，否則會得出8=2。
可見若÷0這個動作是可行的，則會違反很多已定下的axiom和theorem，如得出1=2這個謬論。
Is this Chinese??
Yes
除字寫錯了啦。右邊那個是“余“不是“佘“了，那一棟是要到頂的。

I did not understand, isn't it?
Egil Sandnes : )
所以0可以除以0嗎?
0/0=Any number
（Yes/No)?
0/0算不定型 通常拿來求極限
演算法帶我回來這裡
可不可以講解下80除以5呀？

0*8=0*2，在甚麼情況下0可以拿掉?

用國語教真的很贊一下
Here's my attempt at "proving" ÷0 is a bad idea:

Replace the complex plane with any number space where the observation holds, and we can quickly prove that n ÷ 0 doesn't work in most number spaces.
“0除0，越除越大。”
Undefined number = 未定义数。
Ison Mars Actually that's indeterminate. Don't really know what the Chinese for indeterminate is.
Pointless Sentience "Indeterminate" (不定义) is the same meaning of "Undefined" (未定义).
Great
好棒

7÷0
你把7個東西分給0個人每個人拿到幾個
因為0個人所以東西並沒有分出去代表沒意義
由此可知7÷0沒意義
我以前的時候常常在想...
如果我沒有東西然後要分給7個人..這到底多有意義.... = =

Ahh this is like learning the alphabet in the west
其实并没有那么糟糕

Me gustan mucho sus videos aunque nunca entiendo lo que dicen :v
Bueno loa de inglés les entiendo un poco jeje
我一直有個問題
假設1➗0=x
所以1➗0=1x
所以1➗0➗x=1
所以1➗（0*x）=1
所以1➗0=1
???
依個人淺見：
-見解一
可以把你的第三行寫成x/x=1
但前提是x必須是「同值」；
然而，1/0「沒有固定答案，甚至是沒有答案」，
所以不能以1/0=x，將x設定成可以運算的數。
第四、五行的0*x=0是不成立的，因為1/0=x不能運算。
-見解二
第四行可以寫成
1/(0*(1/0))=1
1/(0/0*1)=1
1/0/0=1
因為0/0=任意數(無意義)
然而1/任意數，不一定等於1，
所以式子不成立。
以上
問題很有趣，讓我動了一下腦，
希望我的回答有幫到你。
