A meticulous teacher set a clever example for the children, my husband and I could not decide.

Fine if mathematics It goes home. In a calm home environment, parents can patiently and slowly explain to their child the basics of working with numbers. And in a noisy classroom, where the teacher needs to convey information to several dozen students at once, the prepared child will feel more confident. The main thing is that parents themselves know mathematics well.

And today's edition. "Site" Asks readers to test their knowledge and solve a few tricky examples from the school curriculum. You will have to use memory to find long-forgotten rules on the far shelf. Otherwise, it is unlikely to be possible to solve examples without mistakes.

Preparing children for mathematics

1. Try to solve the example we put in the preview. Although there are only units and twos, but in arithmetic operations it is quite possible to get confused. Understand what actions to perform in the first place, to confidently and quickly find a solution.
   
   
   
   
2. The second problem, apparently, is given to those who are trying to get a job in some transport company. After all, here we have ships, trucks, and aircraft. Try to find out what the numbers are. And also solve the bottom task in the picture.

3. The last example is the most striking. However, the person who tries to solve this will not be easy. Still, try to master all those peaches, bananas, and oranges to write the right number instead of the question mark.
   
   
   
   

Tips and answers

1. Do division and multiplication first, and then add. By remembering this basic rule from middle (if not junior) school, you will quickly find your way to a solution. As you can see, the answer here was quite simple.
   
   
   
   
2. There are more examples, so in one fell swoop everything will not work out. First we find out that if the sum of three trucks is 15, then one truck hides 15 ÷ 3 = 5. From the second example we find that the ship is 6 ÷ 3 = 2. We also understand that behind the plane there is 12 ÷ 3 = 4. Therefore, the lower example is as follows: 5 + 2 + 4 = 11.
3. The last task is similar to the previous one, but there are difficulties. We find out that the peach hides 30 ÷ 3 = 10. Then eight bananas equal 18 – 10 = 8. So 1 banana is equal to one. From the third example, we understand that one and a half oranges are equal to 4 – 1 = 3. And since an orange and a half is 3 halves, then 1 half of an orange is 1. Then the last example we can write in numbers. The result is 1 + 10 + 3 = 14.
