Whoever gives the answer, it should be easy to understand

Dad's plus Mom's total of 980, note that part of this 980 (970) bought shoes, and part (10 yuan) belongs to you, that is to say, 10 has been included in 980, you can't add any more, you should add 20 (these twenty are not from your parents) a total of 1000

Why do you only owe your parents 490 yuan each? Because you each paid back 10 yuan. So what about the original 1000 yuan, and the remaining 980 yuan?

970 out of 980 bought leather shoes, right? You left for 10 bucks, right? Therefore, the title itself is confusing, it uses 980 and adds 10 pieces of its own, which is not right, because the 10 pieces you left are already counted in the 980 block.

980 should be added, and you will pay back 10 yuan to your parents.

This problem can be easily solved with elementary school math:

Borrowing money is credited: +500+500=1000

Spending money is outgoing: -970=30

Repayment is outgoing: -10-10=10

Balance is positive equity: 10

Debt is negative: -490-490=-980

Assets: -980 + 10 + 970 (shoes) = 0

The problem itself is a thinking trap, and the key to solving it is not to find out the logical error of the problem itself, and to add up negative and positive assets in order to trap people in their own blind spots.

What is the money owed to parents for buying shoes, so it is 490 + 490-10 = 970, that is, the price of leather shoes. That is, expenditures.

So there's no $10 problem. What does 490+490+10 mean?

It's good to calculate this kind of problem by means of income and expenditure, and don't be fooled by the deceptive numbers.

The total income is 490 + 490 = 980

Spend 970 and leave 10 on your own

There is no extra 10

These are two different processes, not simply a matter of additive.

Modern Chinese bai Mandarin is the kind of common language that is easy to understand.

Because there are many local Chinese and ethnic languages in China, and even the ancient vernacular language of the dao has caused inconvenience to cross-regional communication, it is necessary to have a common language that can be applied to most people, which is the "modern Chinese Mandarin" designed by Chinese experts in the last century.

This is the kind of language that is "easy to understand" that is common to the people of the whole country.

Even so, we still don't understand the "easy-to-understand" language, which can only mean that the primary school teachers are not teaching well, and on the other hand, we are not learning well, but most people think that the teachers are not teaching seriously.

As a result, we have an understanding of "easy to understand".

Plain and easy to understand: It is a way for people to use words that are common to everyone and easy for the other party to understand.

If we say, Hong Kong dialect is the "easy-to-understand" Mandarin in Hong Kong.

Then, there is still a difference between Hong Kong dialect and mainland Cantonese, and Hong Kong dialect does not include Cantonese.

But Cantonese people can use Mandarin. Listening, speaking, reading and writing can be in Mandarin.

Hong Kongers also don't need an interpreter to use Mandarin.

Therefore, the kind of language that is easy to understand is the modern Mandarin Chinese that allows all parts of the country and all ethnic groups to communicate in popular language.

Yes. Now is the time of the real vernacular.

Is it necessary to translate vernacular into classical Chinese?

In fact, the problem is not that it cannot be understood in layman's terms.

Rather, it is a gap in the language format of the local dialect.

Although modern Mandarin Chinese has long been popularized in our local area, our primary and secondary school teachers cannot achieve complete modern Mandarin Chinese education.

In their mainstream spoken language, they also always maintain "the local accent does not change and the sideburns fade".

This phenomenon can even appear in textbooks of various subjects.

For this reason, when the teacher cannot teach the Chinese accent correctly, we need to carefully learn the Chinese phonetic transcription and pronounce the Chinese pinyin according to the "Xinhua Dictionary".

And keep reading to practice pronunciation.

It is also necessary to continue to be familiar with and proficient in the language format of Mandarin Chinese through other literary works, radio stations and CCTV news.
