The person who gave the problem also said that whoever solves this problem must have an IQ of 120 or higher.
A typical simple math form of elementary school age based on quantitative thinking, imagination and logical ability has recently been excitedly tried by many netizens. At first glance, it is still quite difficult, the feeling is not easy to move, but after careful observation, many people still give the correct answer.
The problem given is very simple: “Move any ONE stick, so that the calculation 1 – 2 = 4 or 1 47 = 21 becomes correct”. The person who gave the problem also said that whoever solves this problem must have a non-medium IQ.
Many netizens have tried this trick problem. However, many people have to give up before the math problem. So how to move the stick to make this unreasonable calculation correct. The answer is very simple, we just need to move the stick once as follows:
In the first calculation, take the last stick in the letter Z to subtract. So we have the calculation: 11 – 7 = 4.
In the second calculation, take the three rods of the 4 in the second term and move to the first term. Thus we will have the calculation: 14 7 = 21.
After seeing the answer, do you feel surprised because it is so easy? However, this fast-paced calculation still makes many people give up!
Mathematics seems dry but is actually extremely interesting and contains a lot of logical thinking questions, requiring learners to have a high IQ, plus the ability to analyze and closely observe. Many Math puzzles offer “trap” data and we have to think carefully to come up with the right answer.
Before that, the problem of filling in numbers from 1 to 9, was taken in the Math and Vietnamese Grade 3 Weekend Worksheet of the University of Pedagogy Publishing House, making many adults… stunned because it was so difficult. It is known that this is a math problem from 6 years ago, but it was shared by netizens to test their IQ to see who is better… 3rd graders.
At first glance, the problem is just basic calculations, the topic: “Fill in the numbers from 1 to 9 in the blank to get the given result” also seems very… elementary, but when you start working on it. It makes me feel stressed out because I’m too puzzling.
According to experts, the problem has 362,880 possible numbers, but only a few correct answers. With the ability of adults, being able to think and reason logically, after exclusion, you have to try several dozen cases to find the answer.
Many people have had to give up before this trick problem.
