Even a friend of mine made a mistake in solving this cunning example.

Mathematics has always been an important science. And in our digital age, its importance is only growing. And owners of the most important, promising and popular specialties increasingly need to be able to operate well with numbers, know mathematical laws.

And so the editorial board. "Site" Continues to please readers with tricky mathematical tasks. If you're in, help set an example. Such regular classes will not forget how to work with numbers. Besides, it's a good warm-up for the mind. So put the calculator aside and try to solve everything without third-party assistants.



Help me set an example.

1. What arithmetic action will you perform first? Divide and then multiply? Maybe you should pay attention to the brackets first. Or do you start with brackets and then multiply by 3? If you do not remember the basic rules for solving such examples, you will easily get confused. Can you avoid it to give the right answer?
   
   
   
   
2. Perhaps this abundance of twos will cause bad associations among those who did extremely poorly in school. But excellent students will immediately understand what is what and what actions should be performed first.
   
   
   
   
3. And now it is time to indulge in memories of those who, as a schoolboy, consistently received their threes and considered it a good result. Can you handle all these threes now to get the right number instead of the question mark? Also check our answers below.
   
   
   
   

Tips and answers to examples

1. First perform actions in brackets, and then move from left to right. Then we get: 6 ÷ 3(6 – 3) = 6 ÷ 3 × 3 = 2 × 3 = 6. As you can see, the answer is the same as the first digit of the example. Or did your calculations produce a different result?
   
   
   
   
2. Division and multiplication take precedence over addition and subtraction. Therefore, an excellent student transforms the example in the right way: 2 – 2 ÷ 2 + 2 × 2 = 2 – 1 + 4 = 1 + 4 = 5.
   
   
   
   
3. Now it's time to solve the example you saw in the preview. To begin with, remember that 33 = 3 × 3 × 3 = 27, 32 = 9, and 3o = 1. Then the solution will not become a problem 33 – 32 + 3 – 3o = 27 – 9 + 3 – 1 = 20.
