6 ÷ 2(1+2)150 萬人答錯

[zxa402]

6/2+.-.*./?(1+2)

[daniel123557]

@zxa402 你想點

[daniel123557]

@zxa402 題目是6除2乘(1加2)

[Psychial]

其实条问题根本就有漏洞，如果是 6/2(1+2)=6/2(3)， 假如是 2（3）只分6 你会点做呢？6/ 6= 1 . 就是因为问题没有写“X” 6÷2×(1+2) 所有所有人都搞错... 根本就唔是老师或者学生ge错误，是出果条题目ge人太过执着同­无聊...

[andy30930]

那150離跟題目沒隔開，我想說為什麼只有1跟9這答案

(我明明算1350，難道我變智障了= =)

[AnGeLbEaTsKi]

6/2(1+2)=6/2(3)

(3)可用作乘以

=6/2x3=3x3=9

我係咁計



[MekoIce]

根本answer就應該是1,

是(),然後先乘除後加減,

會計到是1的~

[woodykiva]

唔係要括號乘先咩

啫係： 6/2(1+2)

=6/2(3)

=6/6

=1

估唔到台灣同香港個蘋果一樣咁廢...

[whatafkshame]

以我愚見 除可以用分數形式表示 6係分子 2(1+2)係分母 ANS係1

[whatafkshame]

以我愚見 除可以用分數表示 當6係分子,2(2+1)係分母既時候 就係1

反智的社會：

第一，出回題的人有錯，出這樣沒水準的問題

第二，出版商有錯，總編都看不出問題有問題

第三，電視台更錯，電視台不以正視聽，指出教材編制的劣質，反而­指鹿為馬，把答對的人說成答錯。

第四，學者更錯，你們的專業資格是如何得來的，不但不能指出錯誤­，就是求証的心也沒有，怎樣教育下一代?

誤人子弟，指鹿為馬，禍國殃民，亡國之道

@bambo5244 1+2=4??

[ChinaInfiniteBar02]

用計算機直接按0 0咋是1呢,,,,計算機也錯了不 ╮(╯_╰)╭

[chao1037]

@yin19941225

6/2(1+2)150

3x3x150

=1350

[windiel]

當括號代替乘數的時候,

definition說明了其實前面也有個括號, 代表這個數是要優先乘進去之前的數的

i.e. 6 ÷ [2(1+2)]

否則, 只能以6÷2x(1+2) 或 6÷2‧(1+2)表示

所以毫無疑問, 正確答案絕對是1

[narutoli123]

如果跟番呢題數 有括號, 答案係應該1...唉

[Jesusation]

on 9題目,一定係1,話撚到明先乘除後加減,計完括號都係乘入去先­架,個低B大學生扮識計,真係笑到我碌撚咁

[ricoho0613]

6/2(3)=2/2*3

6/2a難道就等於6/2*a=3a??

[s08147f1]

(1+2)的確要先計算,不代表2(1+2)要先計算,而 x 和 ÷ 按先後次序計算

正確計法 : 6÷2(1+2) =6÷2(3) =3(3) =9

非常簡單的題目,我不相信有150萬人錯!

[456789145]

括號一定先算 之後 在從最前算到最後 不就好了=口=

相信很多人都先算 2 x 3 的原因

是 想法 : 先 " 乘 " 除 後加減 被影響了

[Libra1997102]

我比個標題水左 6 ÷ 2X(1+2)X150

[HURTBEARDING]

兩個答案都對 也都錯

9的話是要從前面算到後面 6/2*3

1的話就是2*3先 再除以前面的6 等於1

前後順序搞錯 答案就不一樣了

所以是題目本身就有爭議 完全出錯啦~~

[gundamexia2]

條式e已經有問題 你話4則又得代數又得

一開始打條式出黎又唔講用咩運算去計

想唔錯都好難

[tomkoolman]

都on撚9 的... 小學都曉啦 先乘除 後加減... 咁梗係先乘再除, 仲有小學老師都教先將括號入邊先做... 由內到外.. 點計都答案都係 1 ... 無寫括號上去係你出數果條仆街既問題

[OrzPotter]

@tomkoolman

係要計左括號入面先再先乘除 後加減啊

正確黎講係括號行先

[yin19941225]

我靠

我看到了這個標題

我算了6 / 2(1+2)150

我算了1/150是答案...

[tianshuiwei]

@yin19941225

你答案還是錯的~ 6/2(1+2)150 答案應該1350

[yeongjinken]

@yin19941225

我也是...算了很久...哈

[BoBoCookies]

6 ÷ 2 x 3 = ?

[BoBoCookies]

6 ÷ 2(1+2) = 6 ÷ 2 x 3 = 9 is not ! ~~~~~~

[net893]

@BoBoCookies 你真神 還3呢 回去讀小學吧

[11WIND11]

其實我俾個題目混淆!以爲係6/2(1+2)150 !好彩睇左前PART知道左個題目!最後我係答0岩左!

[georgefunx]

其實題目本身已經有錯在先。

純數的四則運算，本身就不應該寫成6÷2(1+2)，而是要寫成­6÷2．(1+2)或6÷2×(1+2)。

2(1+2)這種寫法是代數寫法，在代數中，2(x+y)，實際­上是要先算的。

看到題目6÷2(1+2)時，回答9或1的，其實都不正確。正確­的答案應該是反問：「這他媽是四則運算題還是代數運算題？」

對方若說是四則運算，我們就先狠狠尻他頭，罵他：「四則運算題不­是加減乘除的運算嗎？你題目的乘號哪裡去了？拿回去重寫！小學沒­畢業啊？四則運算式這樣寫的？！」

對方若說是代數運算，我們也狠狠尻他頭，罵他：「代數運算題中怎­麼沒有代數？拿回去重寫！小學沒畢業啊？沒代數還叫代數運算式？­！」

[hurryporter]

@georgefunx 厲害厲害

[danolin1223]

@georgefunx

聽你在說....X 號碰上括號本來就可以省略了

好好複習一下吧

[georgefunx]

@danolin1223

台灣有很多考試，例如基測、高普特考、技術士檢定等，「爭議題」­、「試題疑義」這種東西是常有的事。

不要以為所有題目本身都是萬無一失的，像下面就是一個很好的例子­，你用「弟弟今年幾歲」這六字在google上搜尋就可找到。

------------------------------­-------------

弟弟今年7歲，他4年後的年齡與哥哥兩年前的年齡相等，問弟弟今­年多少歲？(請你把計算的步驟寫在計算區內)

------------------------------­-------------

學生答7，老師說是9…

其實真正的答案不是7也不是9，而是「老師原本是要問哥哥今年多­少歲的…結果key in錯了」。

[judyhu1108]

@georgefunx 我只覺得題目哪裡怪怪的，但總說不出問題在哪，被大大這麼一點，­哈！原來~~ 大大所言極是啊！！給你一個讚啦~~ ^_^

[michaelsun5656]

@georgefunx 得WO.用你個方法我至計到

[thomastmwc]

@georgefunx  講得好，我愛你!

[a5225720]

@georgefunx

說得很好！

不過

6÷2(x+y) 已知x=1，y=2

數字代進去，不就是6÷2(1+2)？

答案不就是1？

[georgefunx]

抱歉…我提到打頭，完全是開玩笑，現實中千萬別動不動就打別人的­頭。

[michaelsun5656]

如果6/2(1+2)

6唔理 2(1+2)

6/2x3=6/6=1

可以咁計咖wo 0口0

[ccf2424]

IQ 120 以下GE 人會錯@_@?

[balmydrizzle]

式子本身語法根本是錯的，以前2(1+2)這樣寫法根本不存在數­學中，是後來電腦程式設計流行起來，跟傳統數學混在一起的結果。­做老師的傻傻沒分清楚，就這樣出題。現在的老師真糟糕。過去就是­先乘除後加減，哪來什麼括號，純粹是電腦化餘毒，如果考題要放入­電腦的寫法，應該要事先聲明。如果寫成 6 / 2 * ( 1 + 2 )，不就懂了。難不成考這題還可以帶計算機進去=.=

[supermiredo]

連爭議在哪都不知道也敢報導

[cltw666]

if we assumbe (1+2) = X

6/2X = 9

6=18X

X = 6/18!

Clearly the initial assumption of X = (1+3) is wrong!

However,

6/2X = 1

6 = 2X

X = 3 = (1+2)

See the fucking answer now?!?! The answer is not 9!

[iamjign]

@cltw666, you need to rework the problem. you second eq. is wrong. you erroneously assume 6/2X=6/(2X). or let's write it out more explicitly. if you use all multiplication and convert all division into fraction, it is 6*(1/2)*(1+2)

hence, you can clearly see that you mistakenly inverted (1+2). thus, in your 2nd eq. X=[1/(1+2)].

[cltw666]

are you saying 1/2X = (1/2) * X? We know that X can be written as 1X. Can't we write 1/X as 1/1X?

From the beginning. 6/2X is equal to 6/(2X). It is not an assumption. I cannot teach you algebra.

[iamjign]

first, i know algebra very well. secondly, maybe you need to revisit some elementary multiplication rules because you even got it wrong! let alone talking about your so called mastery in algebra.

in a standard process, you always work on the math operation within the bracket first. then you multiple or subtract from left to right. Also, observe the question closely! 6 ÷ 2 x (1+2) = 6 ÷ 2 x 3 using your logic, it would be 6 ÷ 2 x (1/3). learn to walk before trying to run.

iamjign 1 sec ago

[cltw666]

@iamjign Again, it is a dot product. Please do not use cross multiplication. That is exactly what I'm saying. If you want to use cross product, it will be 6 ÷ 2 x (1/3) also equals to 6 x 1/2 x 1/3. which is 6 x (1/(2x3)). Also means 6 x (1/2(1+2)). If you use maple and type in the equation and you'll see why the answer is not 9.

[hk0731]

唔係9呀 6÷ 2(1+2)

3 3冇講明係x定÷ 有灰色地帶的

[mrshyushyu]

6÷ 2(1+2)=?

6÷ 2  X =9

6÷ 2 X =1

三者混淆不清造成的錯誤

這是數學式表達方法應改善的小關鍵

(很多學生因數學表達式的缺陷...........而....­­)

這題很難嗎?

[saangyatfaailok]

diu你d數學，xy系唔等於x*y,老師冇教你?,xy系一個­整體，即系（x*y)， 同樣道理， bc is not equal to b*c, but (b*c)

[fernandotorres99mess]

Apple is right this time! stop your ignorant comments. it is 9 you do INSIDE parenthesis and then go from left to right. If you cant do a fucking math question for life, at least be so smart to use a calculator. Hong kong people all you do is complain shut the fuck up

[cltw666]

@fernandotorres99mess You must be kidding me. Apple is fucking wrong! Have you tried using a scientific calculator? The answer is 1!

[ribenaking]

@cltw666

u try make it into 6/2x3 , see is the answer is 1 or not ? =D

[cltw666]

@ribenaking Please look up the difference between cross product and dot product.

[ws04103794]

我想問,,,,,如果 x÷2y 等於咩???

當 x = 6, y =3,,,,,,,都仲會係等於9?,,,,

如果仲係等於9,,,,,咁就真係9啦,,,,on9個9呀,吊

[saangyatfaailok]

@ws04103794 呢個就系代數， 問題系純數字同代數嘅分別系，純數字系唔可以寫成2(3),而系­2×3，所以呢，2y其實系唔等於2×y而等於(2×y)

[ribenaking]

@ws04103794

你的问题已开始出错了 should be X÷2xY , not X÷2Y...

现在你看下是不是9~

[anttrap321]

其實條數根本就系6÷2x3。好多人比個（）陰到 走去做左2x3 先。

[TangoR34]

Even if you take 2(1+2) as a group you have to take ÷ into account as well.

This makes (÷2)(1+2). Because:(-1)(a-b)=-a+b and not = to (a+b)

Therefore (1+2)÷2=1.5

Then 6x1.5=9

[battlem95]

由左到右=9係好正常點解咁多人會計到1?係咪諗多左?

[TMD13709394]

答案都係其次, 依個問題反映左教育界對書寫沒有明確ge規範

其實個乘號係唔可以省略,

省略ge時候只係因為有x等其它未知數, 因為不想乘號同x搞亂, 先省略掉.

如果冇未知數, 乘號係應該寫出來ge

[saangyatfaailok]

@TMD13709394 I agree with you, as a government education department the Taiwanese should be very clear with their exam question.

@sleepyjuju

你老味你識唔識ga，square同你直接乘除唔撚一樣ga, 2^2=(2*2),有括弧ga

[sleepyjuju]

@saangyatfaailok wow 你老味, I forgot to put another bracket for the 2 ge, do you have to 你老味 people?

what I was trying to show you is when you express square (a+b)² = (a+b)(a+b) = a²+2ab+b². So when a equation written in a way that a number or anything that stick to a bracket will be calculated first.

another example if x=6 y=2 z=(1+2), 6 ÷ 2(1+2) = x÷ yz

If you say answer is 9, x ÷ bc = 9

x will not be 6 anymore, which will prove that 9 as an answer is wrong.

[saangyatfaailok]

@sleepyjuju 純數字，冇所謂代數ga

[TheSuper112233]

@sleepyjuju 6 ÷ 2(3) = 9 not 1, x and ÷ have same value so you solve left to right, (3) have no meaning to it, if the 2 was in there than your are right. i have a math degree from uc berkeley, shame on all the people voted "like" for you stupid comment

[sleepyjuju]

Think of all of the maths rules the you have learned, perhaps algebra? don't you think may be you are wrong? may be you need to get another degree! It is a shame that your university gave you a degree!

[trinitytang0923]

OH MY FUCKING GOD IT IS ONE!!!!!!!!!! WHAT A SHAME!!!!! you always and ALWAYS do the ones in the bracket. so its 6÷2(3). then it becomes 6÷6 = 1. multiplication comes before division.

The standard order of operations, or precedence, is expressed here:

terms inside parenthesis

exponents and roots

multiplication and division

addition and subtraction

Apple. u suck!!!

[fernandotorres99mess]

@trinitytang0923 dumb fuck! you misunderstood the parenthesis...as you said, it only applies if it is INSIDE...not when in this case, simply a multiplication! Apple is right for once stop your bullshit

[saangyatfaailok]

@trinitytang0923

who told u multiplication comes before division??? actually division is the same thing as multiplication, like 6÷2 can be wrote as 6*(1/2), and the standard is from left to right ar!!! not multiplication first

[leosll]

6÷2(1+2) 不等如 6÷2x(1+2).........拜托

[fernandotorres99mess]

@leosll actually it does...dumbshit...you do division before multiplication

[leosll]

唔該, 快去搵個數學教授黎....

2(1+3) 這個一般都是在代數出現的

簡化懂嗎?

如果是(6÷2)(1+2)才是等於9

Apple 你地做傳播的不要亂黎喎.....

[fernandotorres99mess]

@leosll you're a dumbfuck..there is nothing wrong with the way the problem is presented...get yo shit right

[saangyatfaailok]

@leosll 數字與數字之間系冇所謂代數，其實數字之間系唔可以寫成2(3+­1),系一定要有cross product, 代數系乜野情況下出現，系要有unknown number x,y 等等先可以用

[TangoR34]

the layout of the question is designed to mislead anyway. if they put that 2 as a fraction anyone would get it right.

[fernandotorres99mess]

@TangoR34 no it wasnt meant to be misleading dumbshit...the order of operation is that you do division before multiplication

[trinitytang0923]

@fernandotorres99mess its the other way around......

[fernandotorres99mess]

@trinitytang0923 umm are you a stubborn fuck? the order of operation states that you go from left to right..therefore, you do division before multiplication ? hello?
