Will you see the example of the most beloved Soviet teacher?

It is no secret that mathematics is one of the most important subjects in school. And it is not only that the child learns to operate with numbers, which is definitely useful to him in life. Mathematics is generally useful for brain development. And when Kids decide mathematicsThey're progressing very quickly.

Mathematics helps to develop logical thinking, teaches to analyze, systematize, find patterns and draw conclusions. It also provides insights into tactics and strategy, and makes you work with abstract things.

And today's edition. "Site" Think about math for at least a few minutes. Try to solve a few tricky examples that are not as easy as it may seem at first glance. It takes a couple of mathematical rules to find the right answers.



Children decide mathematics

1. To solve the first example, you need to know how to multiply and divide by fraction. And it is not superfluous to know in what order it is necessary to perform all arithmetic operations. If mathematics in school enjoyed your respect, then the relevant knowledge should be preserved.
   
   
   
   
2. To solve the second example, you will have to cope with brackets. There is also division, multiplication and subtraction. Do not get confused in the sequence of mathematical calculations and give an accurate answer.
   
   
   
   
3. The last example will not be particularly difficult if the person remembers how the numbers vary to varying degrees. You have to figure out what the number 5 is to zero. What number should I put in instead of a question mark? Also, do not forget to check our answers in the second part of the article.
   
   
   
   

Tips and answers

1. Multiplying by 0.25 is like dividing by 4. Dividing by 0.25 is like multiplying by 4. So our example becomes more understandable. 4 x 0.25 + 4 ÷ 0.25 = 4 ÷ 4 + 4 × 4 = 1 + 16 = 17.
   
   
   
   
2. First we perform actions in parentheses, then we take up division, and multiply only at the very end. Those are the rules. Therefore, 8 ÷ 4 (8 - 4) = 8 ÷ 4 × 4 = 2 × 4 = 8.
   
   
   
   
3. Any number to the zero power is equal to one. It should be noted that these are numbers other than zero. In our case, the rule is fully followed, so 5o = 1. Then 5 + 5 × 5 + 5o = 5 + 5 × 5 + 1 = 5 + 25 + 1 = 31.
