An example from an elementary school math textbook, not all adults can solve it. Bashny.Net

Let's talk about who this is today. filly. Not filled with any food or drink. A full of knowledge and able to solve complex mathematical problems. Editorial "Site" Asks you to test yourself if you can solve the example of the school curriculum correctly. Only 10% of people on the planet can solve this example in the right sequence.



Mathematics is a school subject that few people like. All these problems, examples, equations require attention and perseverance. For most people, this example seems very difficult. Few people in adulthood use school rules. And modern man has enough electronic devices that in two seconds will calculate any example. But do we only need mathematics to solve examples? Can modern man do without mathematics?



Mathematics is the foundation of all basics. Queen of Science, as they call her. Without mathematical calculations, it is difficult to imagine anything in our world. In addition, the main function in school in mathematics classes was to develop in children the ability to think logically and quickly make decisions. In addition, people with advanced logic and the ability to analyze the number of correctly made decisions are many times more. The brain is a muscle that must be constantly trained. A person who solves mathematical problems until old age does not suffer from Alzheimer’s disease, multiple sclerosis, dementia.



So let's go back to our example. What should be done first to solve this problem? It is very simple, in just two actions. But the most important thing is to determine which action should be done first and which should be done second. Let's remember the sequence in which we were taught to solve examples in math classes. First you need to perform the action of division. It is a priority. Let's remember together what actions are performed first in the examples. If there are brackets, then first we perform actions in brackets, and then behind them.



If there are no brackets, but there is a sign to multiply or divide, then we perform multiplication first, and then division. If in the example there are signs to multiply or divide and plus or minus, then first we do multiplication or division, and then addition and subtraction. So in our example, first we divide. Divide 240 by 2 and get 120, but this is only half of the solved example. Let’s see how this example will be solved.



So the example is half-solved, which means halfway through. The second thing we do is subtract. Because in this case, subtraction is the second action after division. So we subtract 120 out of 250. How much did you do? Check your mathematical knowledge. The correct answer is 130. If you have a different number, try again. Write in the comments if you got the right answer.
