The math problem of Ma Yun Company stumped tens of thousands of graduate students: Xiaoming borrowed 500 yuan from his father, 500 yuan from his mother and bought a pair of shoes.
980 yuan owed by Xiao Ming to his parents has nothing to do with his remaining 10 yuan, 980+ 10 = 990 yuan, which has no practical significance, but a subtraction relationship, 980- 10 = 970 yuan, which shows that he still owes his parents 970 yuan. When this problem is wrongly compared with 990 and 1000, 990 yuan is regarded as the money owed to his parents.
