Every night before going to bed, I make examples so that your brains don’t rust, try it too.

Mathematics is the most important science, a good knowledge of which allows you to have a solid basis for studying anything. Regular classes in mathematics allow you to keep the brain in tone, have a charitable effect on the work of memory.



So today's editorial office. "Site" Dedicate a few minutes to working with numbers. I mean, first examples in mathematics From today's collection will be forced to include intelligence. After all, these tasks are unusual, here one calculator can not do. Try to solve examples in your mind.

First examples in mathematics

1. The first task will be warm-up. We have five rows of numbers, each with an equal sign and a number. Try to understand what logic is hiding here to enter the required number instead of the question mark. You'll be surprised how simple it is.

2. If in the first task it was not necessary to count, then in the second we have four examples at once. You will need to know what numbers are hidden behind each image. Can you handle it fast enough?

3. The last example you've seen in preview. And if you can deal with the previous examples, then these will not be a big obstacle. In any case, do not forget to check our tips and solutions in the second part of the article.
   
   
   
   

Tips and answers

1. It makes little sense to look at the left side of the example. Pay attention to the numbers after each equal sign. So you immediately notice the simplest arithmetic sequence: 4, 3, 2, 1. Therefore, it may be assumed that instead of the question mark, you should enter “0”.
   
   
   
   
2. If we analyze the first example, we understand that one caterpillar is 21 ÷ 3 = 7. Then a couple of hours is 19 – 7 = 12. Therefore, for one hour 12 ÷ 2 = 6. And behind the red flower in this case hides 15 - 7 - 6 = 2. The lower caterpillar is longer by one division, so it will no longer be 7, but 8. A pair of flowers then hides 2 + 2 = 4. And if the clock shows not 6, but 5 hours, then the value of the picture will not be 6, but 5. Then we get this example: 8 + 4 × 5 = 8 + 20 = 28.
   
   
3. We understand that one dog will be 60 ÷ 3 = 20. Then 6 bones are equal to 26 – 20 = 6, and three bones are equal to 3. Therefore, for two bunches of bananas 15 - 3 = 12, for one bunch of bananas - 12 ÷ 2 = 6. The last example is 20 + 3 × 6 = 20 + 18 = 38.
