Police are used to problem solving, so when a little girl reached out and asked for some help with her maths homework, they were happy to help. Ten-year-old Lena Draper sent a Facebook message to her local police department explaining she was having a bit of trouble with her homework assignment.

　　解决问题是警察的职责所在，因此当一位小女孩寻求帮助，想要解决她的数学作业难题时，他们很乐意帮忙。莱娜.德拉珀今年10岁，她在脸书上给当地的警察局发了信息，说明自己的作业遇到了困难。

　　Instead of pointing her in the direction of her teacher, or her parents, Lt. B.J. Gruber decided to respond to her plea for help with a simple: "Ok with what?" Eager Lena quickly shared the offending question (8+29)x15 and was given this helpful tip: "Do the numbers in the parenthesis first so in essence it would be 37 x 15."

　　B.J.格鲁伯少尉并没有让她找父母或者老师帮忙，对于女孩的请求，他很简练的回复道：“难题是什么?”急切的莱娜立刻分享了自己的难题：(8+29)x15，她收到了很有用的解题窍门：“先算括号里面的数字，实际上就是37 x 15。”

　　Lena, realising she was on to a good thing, took the chance to pose another problem, this time (90+27)+(29+15). Lt. Gruber was confident. He had this. Again happy to help, he responded with what he thought was the right answer.

　　莱娜意识到自己碰到了好事，于是借此机会又提出了另一个问题：(90+27)+(29+15)x2。格鲁伯少尉很自信，他可以解决这个难题。他很乐意的再一次提供了帮助，回复了心目中认为的正确答案。

　　What a hero....except there was one tiny issue. He was wrong. The answer he’d given to Lena ended up being incorrect, a fact quickly pointed out by family friends when mum Molly shared the exchange on Facebook.

　　真是一位英雄啊……除了一个小问题—他的答案是错误的。当妈妈莫莉将二者的交流分享在脸书上后，有朋友立刻指出他给莱娜的答案不正确。

　　The actual answer is to add the numbers in the second parentheses and multiply that answer - and that alone - by two, then add it to the numbers in the first parentheses. Lena’s mum, Molly, didn’t seem to mind. "I didn’t believe her and asked for a screen shot. I thought it was pretty funny. And I love that they went ahead with it," she told ABC news .

　　事实上应该是先将第二个括号里的数字相加，然后只将第二个括号算出的数字乘以2，然后再与第一个括号里的数字相加。然而莱娜的妈妈莫莉并不介意，“我不相信她，我要求截图，我认为这很有趣，我很喜欢他们之间的互动。”她告诉美国国家广播公司新闻网。

　　If you’re worried about the police department’s mathematical abilities, stand down. The red-faced Lt. Gruber took to the Marion Police Department’s Facebook page to explain. “Hoping it is truly the thought that counts since apparently I cannot!” he joked. “Especially since the answer was wrong, it was very nice for Molly to acknowledge our attempt to help her daughter with some math homework.”

　　如果你对于警察局的数学能力有所担忧，放心吧。羞愧的格鲁伯少尉在马里昂警察局的脸书主页上写道：“希望这是算得出来的真正的‘答案’，以为显然我算不出来!”他开玩笑道。“尤其是虽然我的答案不正确，但是莫莉承认了我们确实是想帮助她女儿的数学作业，这很好。”

　　It looks like Lena has forgiven him for his wrong answer - he’s visiting her at school. “Tomorrow he’ll be joining my daughter for lunch at school, and is bringing her an autographed shirt to commemorate their going viral,” Molly told CBS .

　　看起来莱娜已经原谅了格鲁伯给的错误的答案—他将要到学校看望她。“明天他将要和我的女儿在学校一起吃午餐，并且送给她一件亲笔签名的衬衫来纪念他们的‘走红’，”莫莉告诉美国国家广播公司新闻网。

　　“I am surprised, I thought it was just a goofy life moment to share with some friends, but it seems to really be striking a chord with people.” Maybe next time Lena’s should just ask her mum’s mates for help...

　　“我很惊喜，我以为这是可以和朋友分享的搞笑的人生经历，然而看起来似乎引起了许多人的关注。”可能下一次她应该向妈妈的朋友寻求帮助……
