6- and 7-Year-Olds Couldn't Solve This Math Test Question, and We're Not Surprised

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)。
