The task of young Stephen Hawking for the development of brisk thinking Bashny.Net

Solving various tasks is useful not only for children, but also for adults. After all, we keep the brain in good shape, which helps to cope with everyday tasks easier and faster.

That’s why we publish interesting stories from time to time. mathematical problems with answersSo that readers can check their mathematical abilities, and exercise for the brain.



Mathematical problems with answers Problem conditions

1. It is rumored that this example at one time interested Stephen Hawking. The famous theoretical physicist and writer was sure that not everyone will be able to find the right solution quickly. Is that true? Will many of our readers be able to find the answer?
   
   
   
   
2. The second task is a New Year’s problem created by an unknown artist (perhaps very young). There's a potted tree and a snowman and a star. Will you be able to calculate in your mind what value should be inscribed instead of the question mark?

3. And finally, the problem about Santa Claus, who is in a hurry. He is in a hurry to deliver gifts to everyone who deserves it. Owners of a mathematical mindset will surely quickly solve this problem. But how many humanitarians will be able to find the right answer?

Problem-solving

1. Those who have been particularly attentive in math classes will probably remember that you should first perform actions in brackets. Therefore, the first thing we find is that 5 – 4 + 1 = 2. And then 18/3*2 = 6*2 = 12.
   
   
   
   
2. From the first example, it becomes clear that the green forest beauty replaces the number 18/3 = 6. Then, from the second example, we find that the yellow star is (16-6) / 2 = 5. And the third example will allow us to deal with the snowman: 14 - 6 - 5 = 3. The last example is 5 + 6 + 3 * 5 - 5. First we multiply, and only then we subtract and add. 11 + 15 - 5 = 21.
   
   
3. As for the last problem, we find from the first example that the number 18/3 = 6 is hidden behind Santa Claus. Then Santa Claus riding a deer is equal
   (22 - 6) / 2 = 8. Therefore, a bag with gifts replaces 18 – 8 – 6 = 4. A deer is 8 – 6 = 2. Then the last example is as follows: 8 + 4 + 2 + 4 = 18.
