The daughter of a professor, a teacher of higher mathematics, offers cavaliers a simple example, but so far there has not been a chosen one, which answers on the move without error.

Many people can’t make friends with mathematics, and some have no desire to do so. As an excuse, they say that they will not need mathematical wisdom in life. Therefore, you should not fill your head with unnecessary information. But can this knowledge be superfluous?

Today's edition. "Site" offer figure out, which was shared by the daughter of a professor, teacher of higher mathematics. She encrypted her phone number here and suggested that the cavaliers try to find the answer.

The beauty believes that if a potential chosen one is not able to solve even such a problem, then there is nothing to talk to him about. Shall we try to surprise her? And then we'll solve a couple more problems so that this math training can be more useful.



Solving a big example

1. What number did this wayward lady encrypt? For the convenience of readers, we provide the task immediately in the image below. Try to solve a big example without mistakes, because the slightest inaccuracy can completely change the final answer. In the second part of the article we will provide our answer. Don't forget to check everything.
   
   
   
   
2. If the first example worked out, then there should be no problems with the second. However, we offer to solve it, because here too there are difficulties. And in the abundance of units you can definitely get confused. Try to avoid mistakes and give the right answer.

Tips and answers

1. This great example can be solved in parts. (√64 × 4 × 102 × 103) = 8 × 4 × 100 × 1000 = 32 × 100 × 1000 = 3,200,000. To divide by 1⁄2 is like multiplying by 2. Therefore (26 ÷ 1⁄2 × 103) = 52 × 1000 = 52,000. Also (√16 × 102 + 70 × 1⁄2) = 4 × 100 + 70 / 2 = 400 + 35 = 435. It remains only to add all three numbers: 3,200,000 + 52,000 + 435 = 3,252,435. Looks like we figured out the number of the math teacher's daughter. It's just hard to know which city she lives in to get the remaining digits of the beauty's phone number.
   
   
   
   
   
   
2. The first thing to do is multiply. Then our example will take the following form: 1 + 1 + 1 + 1 + 1 + 0 + 1 + 1 + 0 + 1 + 1 = 8. As you can see, if you did not miss anything, then finding the right answer is quite simple.
3. First we perform actions in brackets, then multiply, and only then everything else. So we get 6 × 5 – 2 + 5 × 2 = 30 – 2 + 10 = 28 + 10 = 38. Right?
