An arithmetic example that a student of Soviet hardening will solve in thirty seconds

If in school times the solution of mathematical examples was given to a child with difficulty, then in adulthood he will most likely experience problems with this. After all, if a reliable foundation has not been laid, then the person will then simply be too lazy to return to the material already passed through in order to fill the gap in knowledge. And then even the simplest example will not be able to correctly solve.

To check this, the editors of "Site" today will offer several diverse examples from school textbooks at once. Think the solution will be easy? Yes, but only if you remember your math lessons very well. A good opportunity to test yourself.



Solving Mathematical Examples Questions

1. The first example doesn't seem too complicated. But if you look at the answers of many readers, then some people manage to make a mistake here. Try to remember your math teacher and his teachings to find the correct answer. 10/2 (4 - 2) =?
   
   
   
   
   
   
2. The second example is built on just one number. However, different arithmetic operations and the order in which they are performed will confuse anyone, even an attentive reader. (3 + 3) (3 + 3) / (3 + 3) =?
   
   
3. The third example caused quite a stir on the Internet at one time. Users were divided into two camps, and each was confident in his righteousness. Even using smart calculators gave different results. Although the answer is obvious to those who received well-deserved fives in mathematics. 8/2 (2 + 2) =?
   
   
   
   
   
   

Solutions and Answers

1. To solve the example, you need to remember what any math teacher has probably repeated more than once: first we do the actions in parentheses, and then everything else. 10/2 (4 - 2) = 10/2 * 2 = 10 .
   
   
   
   
   
   
2. Remember and apply the parenthesis rule to solve the second example. Then we multiply and divide in order from left to right. (3 + 3) (3 + 3) / (3 + 3) = 6 * 6/6 = 6 .
   
   
   
   
   
   
3. Some users assured that the result should be 16. Others considered the correct result 1. Who has the right to advise whom to improve their knowledge of mathematics. First or second? Why do disagreements arise? This is due to the fact that some people first multiply, and only then divide. Although, according to the rules, multiplication and division should be done in the order of writing (from left to right), unless, of course, parentheses are present here.
   
   Therefore, it would be more correct to solve the example as follows.
   
   8/2 (2 + 2) = 8/2 * 4 = 4 * 4 = 16 .
   
   And in order to consider 1 as the correct answer, you need to slightly change the example by adding one more parentheses. Then 8 / (2 * (2 + 2)) = 8 / (2 * 4) = 1 .
