6、7岁的孩子没法算出这道数学题的答案，我们对此毫不惊讶 [美国媒体]

The internet is having a field day figuring out what the real answer is to a simple math problem. A Twitter user named Louise Bloxham shared a math problem from a Year 2 (equivalent to the first grade in the US) workbook. The tweet and account are now gone but the problem asked "There were some people on a train. 19 people get off the train at the first stop. 17 people get on the train. Now there are 63 people on the train. How many people were on the train to begin with?"

互联网一整天都在忙于算出一道简单数学题的真正答案。一个名叫Louise Bloxham的推特用户分享了一道二年级的数学题（相当于美国一年级的水平），推文已被删除，但这问题的内容是“火车上有一些人，在第一站停车的时候有19个人下车，17个人上车。现在火车上共有63人，那么刚开始的时候火车上共有多少人？”

If you try solving it yourself you'll probably get this setup: X - 19 + 17 = 63. All you have to do is solve for x which gives you 65 as the answer:

如果你试图自己计算这个问题，那么你可能会列出这个算式：X - 19 + 17 = 63，你需要做的就是求解X，从而得到65这个答案：

Yes It is 65. x - 19 + 17 = 63
Therefore x -2 = 63 ...x = 65. Algebraic solution for a y2 Q.

是的，答案是65 。x - 19 + 17 = 63
所以 x -2 = 63 ...x = 65，  只是一个一元方程的代数解。

But if you look further into the comments users start arguing that the answer is 46 not 65.

但如果你继续往下看评论，用户们开始争论答案不是65而是46。

on a teacher's FB group a teacher said it was on the mark scheme as Being 46
- Louise Bloxham (@LouiseBloxham) May 8 2016

在某教师的脸书群组中，一位教师称评分方案上的标准答案是46。

Other commentators became philosophical and said that the math problem fails to factor in the train driver and inspector:

其他评论者开始走哲学风了，他们认为这道数学题没有考虑进火车的驾驶员和巡视员人数这个因素：

Husband says "66 because we've forgotten train driver". But that doesn't factor in inspector...

如用户Mrs Davison说，“我老公说是66，因为我们忘了把列车驾驶员算进去了”。但是这也没把巡视员的人数考虑进去。

The situation apparently became too much for one person who said that everyone was "looking at it algebraically for proof purposes" when it was really just a simple equation.

明明只是一道普通的等式题，如果大家都“从代数证明的角度来看待它”，那么解决方案就太多了。

Yes Question is perfectly fine. We are looking at it algebraically for proof purposes but it's simple add + sub.

网友Olachi Akin说，“是的，这是个好问题。大家都从代数证明的角度来计算它，但是它只是一道简单的加减运算题。”

Although the math question has stumped some parents and young children the main concern here is not whether or not it can be solved but if 6- and 7-year-olds should've been asked it. That answer to that question is simple: if there's this much debate about it with adults then it's not suitable for children.

虽然这个问题难倒了某些家长和孩子，但是我们所关注的不是它是否能被解答出来，而是它是否符合一个6、7岁孩能解决问题的标准。这个问题的答案是非常简单的，但是如果需要与成年人进行过多的讨论才能解决的话，那么它可能不适合作为孩子的作业题（因为讨论的程度对孩子来说过深）。

What a load. Might as well say I don't want my kid to be able to use their brain. Trying and failing is what makes you better at things.
真是一堆废话啊。还不妨说白了我不希望我的孩子能动脑子呢。尝试和失败可以让你在某些事上变得更好。

The answer is zero. No one was "on" the train they were "in" the train.
答案是零。因为没人在火车上，他们在火车里面。

If any adult actually had to write out the problem to solve it needs to reuate their life. This is easily done in your head.
如果任何一个成年人需要把问题写下来才能解决它，那么你明显需要反省一下自己的生活了。这在头脑中就很容易完成的。

I think 63 plus 2 is in the range of a 7 year old.
我认为63+2等于多少这样的问题是7岁左右的孩子可以完成的。

Huh? I don't see any arguments about it being 46. Just one stupid teacher who said it's 46. How do you even come up with that number?
恩？我没有看到任何关于答案是46这个说法的争论。只有一个愚蠢的老师说答案是46，你到底是如何得出那个数字的?

I used to think that my life had no meaning but then I read an article written by Marina Liao. Now I feel pretty good about myself.
我曾经认为我的生活没有任何意义，但是后来我看了一篇Marina Liao写的文章。现在我自我感觉非常良好。

The math question is simple.
这个数学问题很简单啊。
The people who think the answer is something other than 65 are idiots. Even those trying to count the conductor as 63 is the total on the train not passengers on the train.
那些认为答案不是65的人都是一些白痴，即使那些人把售票员算进去，63也是火车上的总人数，而不是火车上的总乘客数。

I think the bigger question is missed. Does a 1st grader (age 6/7) have the reading skills to read the word problem? A poor reader might be a math geek and can solve numbers but would fail at today’s math with all those word problems.
有个更大的问题被大家忽略了。一个读一年级（6到7岁）的孩子能看得懂单词吗？贫穷的读者可能是一个数学怪才，能算出数学问题，但是如今的数学题都是用英文单词描述的，他们可能因为看不懂题目而算不出答案。

There is an obvious net loss of two people here. Why isn’t the answer just 65?? End of story!!!
这里明显漏算了两个人。为什么答案不是65？讨论结束答案就是这个数字！！！

I can't imagine there being a debate about this. It is an absolute… If you truly had 63 people on a train and 17 got on while 19 got off then it is ABSOLUTE 65 people.
我不敢想象竟然会有人因为这个问题而发出争论。这简直是......如果你确定有63个人在火车上，17个上了车，19个下了车，那么绝对是65个人。

Thanks Marina Liao for being a troll with this clickbait crap. Just because people are stupid doesn't mean they are correct.
感谢Marina Liao让我们明白这只是一个骗取点击率的标题党，仅仅因为人们是愚蠢的并不意味着他们就是正确的。

It's a good thing it's not required to be answered to get into pro sports 3/4 of the teams would have an empty roster.
这是一件好事，没有说一定要会解答这道问题才能进职业队，要不然3/4队伍的花名册上会空空如也啊。

63 subtract the newbies(17) add in the original riders(19) you get 65 not that hard if you are too dumb to figure it out it's time you go back to school and that includes teachers.
63减去新上车人数（17）加上到站后下车的原始乘客人数（19），你很轻易就能得出65这个答案。如果你笨到连这个问题都算不出，那么你是时候该回学校重读了，包括（那些认为答案不是65的）老师们。

The math here is pretty simple. Anyone claiming that the answer is 46 should never have made it through school. They're living proof that our school system is inadequate.
这个数学题很简单。任何声称答案是46的人应该都没上完学。他们是证明我们学校制度体系不健全的活生生的证据。
