Remember the mathematical rules of elementary school and solve the example without hesitation

In ardent haters of mathematics, all its wisdom and rules are poorly held in mind. And it takes a couple of years not to deal with any problems and examples, as the principles of their solution are completely forgotten. But not every adult remembers it. How to solve an example correctly with brackets or other “complex elements”.

Today's edition. "Site" It invites readers to understand a few examples that seriously puzzle adults and educated people. Try to distract yourself from worries and household affairs. Solve examples and compare your answers with ours. Perhaps these simple tasks will allow you to mentally return to a carefree childhood for at least a couple of minutes.



How to solve an example correctly

1. At first glance, it seems that there is nothing complicated in the first example. However, mistakes are often made in the decision. Try to open the brackets by all the rules so that the final answer is 100% correct. And if in doubt, then check yourself by our tips in the second part of the article.
   
   
   
   
2. In the second example, there are all four basic mathematical operations. Therefore, we will have to perform division, multiplication, addition, and subtraction. We hope that you still understand in what order to do everything. And put the right number instead of the question mark.
   
   
   
   
3. The third example is the most cumbersome, but you've seen it before. We assure you that a calculator is not required here (and it will not help much). However, if you remember the mathematical rules of elementary school, the answer will soon be found. Quick, accurate and without a single hesitation!
   
   
   
   

Tips and answers

1. The first step is to open the brackets, and then perform the remaining mathematical operations in the example. Therefore, 8 ÷ 4 (5 - 3) = 8 ÷ 4 × 2 = 2 × 2 = 4. Everything is very simple if you follow the rules.
   
   
   
   
2. For the correct solution of the second example, it is necessary to remember that division and multiplication are performed first. 2 × 5 + 5 ÷ 5 - 2 = 10 + 1 - 2 = 9. Too easy again?
   
   
   
   
3. Again, we need to deal with brackets first. Therefore 24 ÷ 6 (4 – 3 + 2 – 1) = 24 ÷ 6 × 2 = 4 × 2 = 8.
   
   
   
   

We hope that these examples helped you to warm up a little intellectually. Solve our other, more complex examples. I also find solutions to problems that really make you think.
