We strain the convolutions and recall school knowledge to solve this difficult example with brackets.

Interesting mathematics extracurricular It's necessary for every student. After all, in noisy lessons it is difficult to learn the material at a good level. But at home in a calm atmosphere you can deal with any mathematical wisdom. And this process will be exciting and pleasant. And in such an atmosphere, any knowledge gained is best fixed in memory.



Today's edition. "Site" I would like to take a few examples slowly. And here, both adult readers and schoolchildren can search for a solution. Try your hand, remember the mathematical rules and give the right answers. Can we do that?

1. In the first task, we have examples where food is drawn instead of numbers. Try to figure out the numbers behind cheeseburgers, pizza slices and ice cream cones. After all, only with all this information, you can solve the lower example.

2. In the second example, you will have to deal with emoji. Here we have a know-it-all smiley face (who is wearing glasses), embracing a smiley face and kissing a smiley face. There are also different numbers behind each emoji. And you have to find these numbers to solve the bottom example. 587264

3. Finally, let me give you an example that you may have seen in the preview. There are brackets and various arithmetic operations. What is there to decide and in what order, so that a strict teacher of mathematics did not slap a deuce, but praised for excellent knowledge of the material passed?
   
   
   
   

Tips and answers

1. If three cheeseburgers equal 300, then one hides 300 ÷ 3 = 100. Then, from the second example, we understand that two horns of ice cream are equal to 200 – 100 = 100. And so behind one horn of ice cream is 100 ÷ 2 = 50. Then for two slices of pizza should be 90 - 50 = 40. And behind one piece of pizza is 40 ÷ 2 = 20. So now we can write down the last example in numbers: 100 + 50 + 40 = 190.
   
   
   
   
   
   
2. Behind the know-it-all smiley face is 33 ÷ 3 = 11. Then the two hugging emojis should be 13 – 11 = 2. And so one such warm smiley hides a unit behind it. From the third example, we understand that the kissing emoji is 11 – 1 – 1 = 9. Then, without any problems or hesitation, we write down the lower example with numbers. We get 9 + 11 + 11 + 1 = 32.
   
   
3. Now it is the turn of the most common example. Here, first of all, you need to solve actions in brackets, and only then go through everything else from left to right. Then the example will be solved by the following stages: 15 ÷ 3(4 + 3 - 2) = 15 ÷ 3 × 5 = 5 × 5 = 25.
