You're smarter than a Japanese first grader if you master a mysterious example.

Mathematical tasks for students can be quite difficult. Even an adult with a college degree (and a lot of experience) can find a solution. And if the reader solved such problems for the last time a couple of decades ago, now there is almost no chance to remember anything.

Today's edition. "Site" It offers some fascinating numbers assignments where many adults get lost and give the wrong answers. Of course, those caring parents who regularly help their children with homework, for sure will easily solve any problem. But will everyone else manage? Try your hand.



Challenges for schoolchildren

1. This simple example became popular in Japan and then gained popularity around the world thanks to social media. This is probably because a lot of people don’t like math (and in faraway Japan, either). The note also indicates that this example was in textbooks back in the 80s, but then it could easily solve 90% of students. Today, only 60% of young people can cope with this task. Is it true that even in Japan, mathematics is getting worse? Anyway, try to find a solution to this short example.
   
   
   
   
   
   
2. As a second task, we offer another clever example. There are brackets, and division, and multiplication. You'll have to add up the numbers. Try to remember the main rules that a good math teacher never tired of repeating. Without this knowledge, it will be difficult to solve this example correctly.
   
   
   
   
3. And finally, another intricate example, when solving which is quite easy to get confused. Of course, hard excellent students will easily get out of this difficult situation. Test your knowledge of mathematics and try to find the right answer in this case.
   
   
   
   

Task tips

1. The main problem here is that many simply do not remember how to divide a number by fraction. But this mathematical operation will be the first. First you need to divide and multiply, and only then add and subtract. Dividing a number by a fraction is like multiplying it by the same fraction, having previously changed the numerator and denominator places. Then our example gets a slightly different, but more understandable form: 9 - 3 * 3 + 1 = 9 - 9 + 1 = 1.
   
   
   
   
   
   
2. Immediately, first of all, you need to perform actions in brackets, and then perform the remaining operations from left to right. Then we get 9 / 3 * 3 = 3 * 3 = 9.
3. The last example seems rather cumbersome, but it should not be frightening. Recalling the teachings of a good teacher, we simplify the example: 3 + 3 * (3 + 0) + 0 = 3 + 3 * 3 = 12.
