Mastering arithmetic according to Sergey Sergeevich's method. The story.
On the train to Anapa, Sergey Sergeevich saw a crying boy.
"Where are your parents?" Sergey Sergeevich asked the boy.
"Here, nearby," the boy waved his hand to the side.
"Why are you crying?"
"I get bad grades, and the kids don't want to be friends with me."
"You get bad grades? In what subject?"
"Social Science. The teacher asks me: "If Russian citizens bought forty tons of gold at a price of 8,500 rubles per gram, how much money did they spend?" "I answer: three hundred and forty trillion rubles." She asks me: "And if they bought 300 tons of gold, how much money did they spend?" I answer: two sextillion 550 trillion rubles."
"Are you sure you are not confused - with (by) the zeros?" - Sergey Sergeevich asked the boy. - "How many grams are in 1 ton of gold? One ton is one thousand kilograms and one million grams. Is that right?"
"That's right," the boy agreed hesitantly.
"And how much does one ton of gold cost if one gram costs 8,500 rubles? 8 billion 500 million rubles. Right?"
"That's right...," the boy confirmed.
"We multiply 8,500,000,000 by 40. We get 340 billion rubles. Is that the amount we will get?"
"Yes..."
"300 is about nine times more than 40. If 340 we will multiply by 9 it will be about 3 trillion. Therefore, we are not talking about sextillions. But to be precise, we multiply 8 billion 500 million by 300 and we get 2 trillion 550 billion rubles. Is it right?"
"I think it is...", - the boy confirmed.
"Therefore, not two sextillion 550 trillion rubles, but 2 trillion 550 billion rubles. You are confused - with (by) the zeros..."
The boy sighed bitterly.
Sergey Sergeevich smiled and encouraged the boy-loser: "Do you know how much money Russian citizens deposited in banks?"
"How much?"
"They say about different figures (volumes). But - in any case - they say about several tens of trillions of rubles. Some even compare the amount of citizens' bank deposits with the approximate size of the state budget expenditure (about 40 trillion rubles)."
"Oh!"
"Yes! And why did the teacher ask you about the price of 300 tons of gold?"
"I don't know..."
"She thinks that 300 tons - this is the figure of the annual gold production in Russia."
"Yes..."
The boy - while he was talking to Sergey Sergeevich - stopped crying, and even became more cheerful.
"Well, that's it. Study arithmetic, boy, you will be rich and healthy. You will getting high grades, and the kids will be friends with you!" - Sergey Sergeevich encouraged the boy.
"Are you probably the head of some bank?" - the boy asked.
"I like walking, and I like to feed the birds in the morning," Sergey Sergeevich answered with a smile.
"Thank you for your studies, for your classes!" - the cheerful boy ran to his parents.
