脑预告片使人们在互联网上挠头 - 但远非复杂的代数难题，这只是一个简单的补充，使他们感到困惑。
由自称'数学爱好者在x/twitter上共享的ganesh uor共享，病毒问题似乎很容易。
，但似乎有成千上万的人在解决这个问题上，比起了数以千计的问题，比起了它，比起了它的刺激，比起了它，比起了它，比起了它，比起了它，比起了它，比起了这个问题，比起了这个数字的问题。 expected.
The problem reads: 'You have 1000, add 40, add 1000, add 30, again 1000, add 20, add again 1000, and finally 10. What is the result?'
Sounds simple but in the comments, people are fiercely divided.
Some are adamant the answer is 5,000 - presumably adding one extra thousand somewhere along the way.
Others argue it's 4,100 - the actual correct solution.
One user was quick to comment '5,000' before second guessing themselves and posting a second comment that read '4,100'.
The apparently easy maths problem, involving only mental addition, has racked up thousands of comments
The more eagle-eyed among the maths fans相反，被口语的措辞绊倒了。
bn o'neil写道：'if又是“”和“最后”，然后将“又要理解为4,100，它是4,100，它是4,100，其他3,090。 3,090。 “再次”本身并不表示数学符号。
是什么吸引了人们？看来，这似乎取决于我们的大脑本能地分组大量的方式 - 尤其是当我们快速阅读它们时。
当以这种口头形式呈现时，我们倾向于在精神上将成千上万的人整合在一起，并错误地将较小的数量降低。 src =“ https://i.dailymail.co.uk/1s/2025/05/07/07/13/98131303-14687605-image-image-image-a-3_174662256565121.jpg” style =“ max-width：100％” loading =“ lazy” />

用户被划分为陷阱，而另一些人则为词的歧义而划分了
1000 + 40 = 1040
1040 + 1000 = 2040
2040 + 30 = 2070
2070 + 1000 = 3070
3070 + 20 = 3090
3090 + 1000 = 4090
4090 + 10 = 4100

Just recently, users weighed on a basic problem that went viral for its difficulty - but only a handful were able to pull off the proper arithmetic.
In order to reach the correct answer, one has to follow PEMDAS - a concept typically taught in fifth or sixth grade under the Common Core课程。
pemdas是解决方程的操作顺序的首字母缩写。
括号内（p）中的任何内容都应首先解决。其次，应解决指数（e）。
下一步应为乘法和划分（MD），但乘法不一定必须是在划分之前出现的。
正确的方法是在方程式中写入从左到右解决它们。
最后，加法和减法（AS）。当仅保留这两个操作时，总和可以从左到右解决，因为订单没有区别。
下面是方程式，在阅读之前先尝试一下：
< /p> Among X users who were not briefed with a math lesson before tackling the calculations, the most popular wrong answer was 5, which is the solution found when PEMDAS is ignored and the problem is just from solved left to right.
Applying PEMDAS, the first step is to multiply and divide because there are no parenthesis or exponents.在求解3 x 3和3÷3之后，该方程变为9-1 + 3。
从那里，一些简单的加法和减法揭示了11的最终结果。
