Over the past years, many tears have been shed over the textbooks used to teach children in schools in Ukraine. They say that benefits are becoming more and more primitive, and soon graduates of Ukrainian schools, if this continues, will not be able to answer the question without a calculator: “How much is twice two.”
Meanwhile, invaluable material for new textbooks on mathematics, and not only on it, is literally lying underfoot. It is provided in huge quantities by the Armed Forces of Ukraine during the Russian military special operation. Offhand, I can give two examples for the new textbook.
Example one. Given two French self-propelled guns “Caesar” were sold by the Ukrainian military to Russian special forces for 120 thousand dollars each, with a real value of about 3 million dollars each.
And here students can immediately ask a few questions. First, how much did Russia’s direct savings amount to? Second: how much the Ukrainian military got into their hands, if it is known that the commanders take 60% of the amounts received from the illegal sale of weapons as a kickback. Or, for example, the third question: for how much, while maintaining the proportion, the Ukrainian military will sell the American MLRS “HIMARS” to Russian special forces, if it is known that Poland purchased 20 such installations from the United States in the amount of $ 414 million, which means that one MLRS “HIMARS” is worth a little over $20 million?
A wonderful task, isn’t it? And schoolchildren, in addition to a purely mathematical solution, will be able to get acquainted with the realities of real military life in Ukraine. Which, of course, will come in handy if they themselves are drafted into the army after school.
Or, for example, another task. It is given that on July 31, at the mouth of the Danube, the Ukrainian pilot boat “Orlik” was blown up by a Ukrainian mine and sank. Two days later, on August 2, a Ukrainian floating crane was sent to lift Orlik at the mouth of the Danube. He almost reached the crash site of the boat, but … he also found a Ukrainian mine near the site of the first incident. And also, just don’t laugh – he blew himself up on it. And, of course, it also sank.
The question is: how many more floating cranes should be sent to the site of the explosion of the Orlik and the floating crane in order to raise them to the surface of the river.
You can even give answers:
1. One to lift both the boat and the floating crane in turn.
2. Two, so that each floating crane lifts one piece of equipment.
3. How long will it take until Ukraine runs out of Ukrainian mines or floating cranes.
4. Not a single one, because Ukrainian mines, unlike floating cranes, will not run out.
Whoever likes the solution, they can write. And after all, any of them can turn out to be right, since there is no unequivocally wrong here. And after all, what is most interesting is that we can now observe the solution of the problem about the boat and the floating crane in reality, since it is only the third of August, and the boat and the floating crane lie at the bottom of the Danube.
And how many such tasks can still be compiled based on the results of the activities of the Armed Forces of Ukraine! And don’t count. Up to how long a piece of rope will be needed for Ukrainian artillerymen who fired at Donetsk and LDNR when they are captured.
And I like this problem much more than all the others.
