Xiao Ming borrowed 500 yuan from his father, bought a pair of shoes, used 970 yuan, and left 30 yuan. Xiao Ming also returned 10 yuan to his parents. Xiao Ming still had 10 yuan. Xiao Ming lost his parents' 490490 + 490 2980, plus Xiao Ming's 102 in 990, where's 10 yuan?
When you buy 970 shoes, you use your parents' 485. If you have 30 left, you give your parents 10. If you have 10485 plus 10, you will get 495495. If you add 495, you will get 990. If you add 10 yuan, you will get 1000 yuan
There is another question. Xiao Ming borrows 500 yuan from his parents. It costs 970 yuan to buy shoes, and there is 30 yuan left. He also gives 10 yuan to his parents, and there is 10 yuan left. Now he owes 980 yuan to his parents, plus the 10 yuan he has left, 990 yuan. Where is the 10 yuan left? This is also the problem of borrowing in accounting
Logic misleading
They borrowed 500 yuan from their parents, and 970 yuan was used for shopping. The remaining 30 yuan was returned to their parents, 10 yuan each,
This problem is misleading. In fact, it is to borrow 980 yuan from Mom and dad. Don't be cheated. You can see that 970 + 10 = 980. If you borrow 500 + 500 and subtract 20, you will get 980. So if you buy 970, you will get 10
I borrowed 500 yuan from my father, then borrowed 500 yuan from my mother, bought a pair of shoes, spent 970 yuan, left 30 yuan, then returned 10 yuan to my father, returned 10 yuan to my mother, I still had 10 yuan left. Later I thought about it, I owed 490 yuan to my father, 490 yuan to my mother, I still had 10 yuan left, where is 10 yuan left
This problem can be easily solved by primary school mathematics
Borrowing money is recorded as + 500 + 500 = 1000
Spending money for Accounting: - 970 = 30
Pay back for the account: - 10-10 = 10
Assets with positive balance: 10
Debts are negative assets: - 490-490 = - 980
Assets: - 980 + 10 + 970 (shoes) = 0
The problem itself is a thinking trap. The key to solve the problem is not to answer the question, but to find out the logical error of the problem itself. Adding negative assets and positive assets is just to trap people in their own thinking blind spots
