The head of the housing and communal services seemed that he was a natural mathematician, but a cunning example knocked him off his rut.

Mathematics is an interesting science. But those people who did not do it during school, probably think differently. Therefore, they prefer not to remember all these intricate rules with formulas and theorems with axioms.

Needless to say, if even simple examples that can be solved by elementary school students, sometimes turn out to be too much for adult uncles and aunts who occupy serious positions.

And today's edition. "Site" He suggests stretching the brain a little, solving several simple mathematical tasks. Such Examples for Independent Solutions In just a few minutes, they will show you how well you remember the mathematical rules that a strict math teacher tried so hard to put into the heads of students.



Examples for self-solving

1. The first example seems pretty simple. What can be difficult if you add two to three? And everything else does not seem unprecedented. However, to correctly solve the whole example is not for everyone. As a result, many people get different answers, although there is only one correct answer. The only question is whether you can find the right answer.
   
   
   
   
2. The second example already seems more complicated, because here you will have to divide and multiply, and you need to deal with brackets correctly. Try to remember the basic mathematical rules, without which you can not do when solving this example. And don't forget to check your answer with ours. We hope the answers match.
   
   
   
   
3. In the last example, there is a zero that can confuse many. Be careful not to make a mistake that will make your answer wrong. And at the same time offer to solve this and our other examples to younger students (if there are any nearby). Let’s see who is better at such tasks: adults or children.
   
   
   
   

Tips and answers

1. The first thing you need to deal with brackets, only then do the multiplication, and add “3” will have at the very end. Therefore, the example will take the following form: 3 + 2 * 2 = 3 + 4 = 7.
   
   
   
   
2. Brackets and in the second example should be considered first. However, after brackets you will have to divide, and only then multiply. So we get: 18 ÷ 3 * 3 = 6 * 3 = 18. If the sequence of actions is incorrect, you can get, for example, 2.
3. First we perform division and multiplication, and then add and subtract. So we get 9 – 0 + 1 = 10. It's pretty simple!
   
   
   
   

We hope that solving these examples is not a problem for you. In any case, share your answers in the comments. And solve other interesting examples that not everyone managed to cope with.
