Think your maths is up to scratch? You might want to peruse the below test and think again.

　　你认为自己的数学很优秀吗?那么你可能想要阅读下面的测试，然后再认真考虑一下喽。

　　A bizarre intelligence test, which involves adding up a sequence of numbers, is sweeping the internet - and leaving users dumbfounded in the process.

　　这项奇怪的智力测试涉及一连串数字的运算，该题横扫互联网，让答题者对求解过程目瞪口呆。

　　The test, created by Go Tumble and shared on Wikr, asks users to ’think outside the box’ by working out two different but correct answers to a series of equations.

　　这个测试是由久﹒川柏和维克尔共同创建的，它要求用户“跳出思维框架”， 从而在一系列方程式中找出两个不同但均正确的答案。

　　Makers write: ’Firstly, think outside the box! This maths riddle is not that simple. Even though there’s usually one right answer for maths problems, two common solutions are causing heated debates all over the world.’

　　出题人写道:“首先，跳出思维框架!这个数学题并不像表面那么简单。尽管数学问题通常只有一个正确答案，但此题却有两种不同的答案，这在全世界引起了激烈的争论。”

　　The makers say that only one in 1,000 people can figure out the second possible answer to the test, so can you?

　　出题人说，只有1/1000的人能想出第二个可能的答案，那么你能吗?

　　SOLUTION 1

　　答案1：

　　The makers explain that most people will begin by adding 1 + 4 to reach the answer 5.

　　出题人说，大多数人首先会用1+4得到第一行式子的答案5。

　　Then they’ll add 2 + 5 to the sum of 5 to get an answer of 12.

　　然后使用5加上2+5，得到第二行式子的答案12。

　　The majority of users will use the same process in the next line, adding 3 + 6 to get 9, then add nine to the sum in the equation above (12) to reach the figure 21.

　　大多数人将在下个式子中使用相同的流程：3+6得到9，然后将9加上式结果12，得到图中第三行式子答案21。

　　In the last stage, they will add 8 + 11 to get 19, before adding it to the sum of the previous line (21) to get 40.

　　最后，8+11得到19，再将19加上一行结果21，得到答案40。

　　While makers say that 40 is a widely accepted and correct answer, there’s another answer - and only a select few will reach it.

　　出题人表示40是一个被广泛接受的正确答案，但此题还有另外一个答案，仅有少数人能得到这个答案。

　　SOLUTION 2

　　答案2：

　　While makers say that, of course, 1 + 4 = 5, intelligent people will get the answer by adding 1 to 4 x 1.

　　出题人说，1+4=5当然正确，不过聪明的人也会想到答案1+4x1=5。

　　Using that formula, they’ll add 2 to 2 x 5 to get 12.

　　根据这种公式，他们会用2+2x5得到12。

　　They’ll then add 3 to 6 x 3 to get 21.

　　然后3+6x3得到21。

　　And to reach the final and alternate answer, they’ll add 8 to 11 x 8 to get 96.

　　最终，可以得到另外一种正确答案，即8+11x8得到96。
