It is not uncommon for certain puzzles to go viral and capture the attention of many people, both because of their apparent simplicity and their underlying complexity.
The appeal of mathematical puzzles
Mathematical puzzles have a universal appeal. They push us to think creatively and find intelligent solutions to problems. That’s why they are often shared and discussed online and spread so virally.
A recent example is a middle school math puzzle that has baffled many internet users in their 20s and 30s. This puzzle, which involved a combination of simple arithmetic operations, troubled Internet users. However, if you follow the basic rules of mathematics, the answer is not that difficult to find. The secret to solving this puzzle lay in identifying operational priorities and understanding the basic rules of mathematics.
The importance of analysis and conclusion
Mathematical puzzles often emphasize our ability to analyze and deduce information, rather than our pure mathematical knowledge. These skills are essential for solving complex problems and are also tested through IQ tests.

An example of this type of puzzle is a number sequence with a question mark representing a missing digit. To solve this puzzle, it is necessary to apply logic and analysis, carefully examining the order and looking for patterns or relationships between the numbers.
Math skills and personality
Math puzzles can also teach us more about our personalities and the way others perceive us. By understanding how we approach and solve problems, we can better understand our strengths and weaknesses and the way we interact with others.
Interestingly, math skills have been studied by science. Researchers have wondered whether math teachers and math whizzes might have a biological advantage. One study examined whether a person’s math skills were related to levels of two important neurotransmitters involved in learning: GABA and glutamate.
Researchers in cognitive neuroscience at the University of Oxford in the United Kingdom examined GABA and glutamate levels in the brain to find out whether these neurotransmitters can predict future math skills. GABA and glutamate are two natural amino acids that play complementary roles: the first inhibits or reduces the activity of neurons in the brain, while the second makes them more active. Your values fluctuate over the course of your life.
Not only did the researchers find a connection between math skills and neurotransmitter levels, but they also found that these levels changed as children grew and became adults. This research was published in the journal PLOS Biology.
Here is the answer
Firstly, it is important to take a pragmatic approach and identify priority actions. In the fourth grade math curriculum, multiplication and division must occur before addition and subtraction. Therefore, it is not appropriate to calculate additions and subtractions linearly, e.g. E.g. first 9 – 3, then 6 – (1/3) and then 18 + 1, as this would produce false, erroneous results, as is the case for most internet users.
However, the question of fraction remains. How do you divide it? In reality, you need to use a method called “inverse multiplication.” Therefore, we need to multiply the numerator by the denominator, which is also equal to 3. So the expression becomes (9 – 3×3 + 1). Then you simply multiply the numerators and denominators together to simplify the fraction. So (3×3/1) is equal to 9. Now everything just needs to be calculated: 9 – 9 + 1 = 1. And that’s all, that’s all.
