I borrowed 500 from my father, borrowed 500 from my mother, bought a pair of shoes, and used 970. The remaining 30 yuan, I returned 10 yuan to my father, 10 yuan to my mother, and I left 10 yuan. I owe 490 yuan to my father, 490490 + 490 = 980 yuan to my mother. Plus my own 10 yuan = 990 yuan, where is the remaining 10 yuan? Who else has such a question?

They asked if there were any similar questions, and what did you answer

Xiao Ming borrowed 500 yuan from his father and 500 yuan from his mother. He went to the shoe store to buy a pair of shoes and spent 970 yuan. The rest was 30 yuan. He returned 10 yuan to his father and 10 yuan to his mother. He left 10 yuan. Finally, he owed 490 yuan to his father and 490 yuan to his mother,
490 yuan * 2 equals 980 yuan, plus 10 yuan, equals 990 yuan. Where is the other 10 yuan?

If you return 10 yuan to your mother, you will owe 490 yuan to your father and 480 yuan to your mother. A total of 970 yuan is owed, and 30 yuan has already been returned. If you don't add 10 yuan left by Xiaoming, 20 yuan has already been returned. If you add 10 yuan left by Xiaoming, 20 yuan seems to be 10 yuan left. In a word, the 10 yuan has already been returned. Adding up the money owed and the money left by Xiaoming, of course, 10 yuan is less
Maybe not. It's been a long time

Xiaorui borrowed 500 yuan from her father and 500 yuan from her mother. She bought a pair of sneakers and spent 970 yuan. There was 30 yuan left. Xiaorui returned it to her father
Xiaorui borrowed 500 yuan from her father and 500 yuan from her mother. She spent 970 yuan on a pair of sneakers and left 30 yuan. Xiaorui returned 10 yuan to her father and 10 yuan to her mother. She left 10 yuan. Xiaorui still owes 490 yuan to her father and 490 yuan to her mother (490 + 490 = 980 yuan) and 980 yuan plus 10 yuan to her mother = 990 yuan. Where is the remaining 10 yuan?

First of all, if you return 10 yuan, it's equivalent to borrowing 980 shoes, 970 shoes, and 10 yuan. Your 20 yuan is just right

Xiao Ming borrowed 500 yuan from his father and 500 yuan from his mother. He bought 970 yuan for a pair of shoes and left 30 yuan. He returned 10 yuan to his father, 10 yuan to his mother and 10 yuan to himself. He owed 490 yuan to his father, 490 yuan to his mother and 490 + 490 = 980 yuan. He still had 10 yuan. Where did he go?

This is a logical concept of words. 980 of them are related to the return of 10 yuan to their parents. Their 10 yuan is related to 970 yuan and 30 yuan to buy shoes
