Grandson - the guy does not miss, solves difficult examples and makes Grandma remember mathematics

Addition examples It’s a simple task that even a three-man can do. You think it's that basic, too? We're in the newsroom. "Site" We found several interesting examples of addition, each of which has its own catch.

And therefore, finding the right solution will not work for every arrogant adult. Especially if you didn’t take math lessons seriously.

And the older the person, the harder it will be to cope with the numbers. Therefore, you can check not only yourself, but also older relatives of the Soviet hardening. Good. warm-up.



Do you think that you can not be intimidated by examples of addition? Maybe it is. But we very much doubt that many adults who last opened a math textbook decades ago remember even the basic rules. It's time to check it out.

1. The first example you can see in the preview. To solve it, you need only a few simple actions that can be performed without a pen and notebook. But you need to remember how to deal with negative numbers. Can I get the right answer?
   
   
   
   
2. In the second task, there are several examples at once, but each of them uses only addition. Can you calculate the values behind each geometric figure to solve the last example?

3. And to solve the last task, we suggest dealing with strawberries, plums and lemons. All the conditions of this problem can be seen in the picture below. To solve, you will have to perform not only addition, but also some other operations. But don’t worry, there’s nothing complicated. Just be careful and there will be an answer.

Tips and solutions

1. There is a rule that a negative number (which with a minus) evenly becomes positive, and oddly remains negative. And indeed (-3)2 = 9, and (-3)3 = -27. But if there are no brackets, then a negative number in an even or odd degree will remain negative. Remembering these simple rules from school, we try to solve our example. The result is -32 + 32 + (-3)2 + 32 = -9 + 9 + 9 = 18.
   
   
   
   
   
   
2. Immediately calculate which numbers are hidden behind each geometric figure. Behind the circle we have 45/3 = 15. Then behind the square is hidden (23 – 15) / 2 = 4. So behind the polygon we have (10-4) / 2 = 3. Then the last example is as follows: 3 + 4 + 4 + 15 = 26.
3. A similar solution has the last problem with a colorful condition. Behind strawberries lies 15/3 = 5. Behind each plum (13 – 5) / 2 = 4. But the lemon is 12 – 5 – 4 = 3. Then the last example becomes absolutely clear: 5 * 2 + 4 + 3 * 3 = 23.
   
   
   
   

Here, even simple examples of addition can be so slightly confusing. Do not forget to write in the comments, whether you managed to find the right solution for each task.
