I think we have two answers 1 and 2 ,asics white, respectively ,asics gt 2150 black 温家宝：采用多种办法坚定避免物价过快上涨, and if you answer 0 , then you are really completely idiot proof
I think the answer is 2 , there are two methods
Accounting Law :
gross income : 9 +11 = 20
Total expenditure : 8 +10 = 18
balances : 2

practical method :
example, you have 10 bucks , You spent 8 bucks to buy chicken
10-8 = 2 You have two yuan
sell your nine yuan ,nike air maxes 95, 2 +9 = 11, you have got 11 yuan and 10 yuan to buy your
Back 11-10 = 1, the rest of your body you 11 yuan 1 yuan
sold, 1 +11 = 12, your body will have a 12 per
than your original 10 yuan, to make the 2 Yuan

formula
0-8 +9-10 +11 = 2


analysis on the wrong answer , answer a lot of people , because that is the second transaction When that lost a dollar to see their analysis :
who has 8 million, eight yuan to buy , sell nine yuan ,louis vuitton tie, who has nine yuan to 10 yuan
bought it , just like other people by 1 million, And then sold for 11 yuan, profit of 1 million, then that person back to this one yuan , equal to not make

explains nothing seems wrong, but one of the loopholes is that you take 1 million, by After the money is 10 yuan , 11 yuan was earned selling 1 million, back to him is tantamount to not make a profit,coach backpacks on sale, which was wrong , in fact, you earn 1 million, because you're only 9 million, into a 11 Dollars, but with others , by 1 million,coach scarves, back to him is 2-1 = 1 , not 0
borrowed one yuan you had 9 million, borrowed money is not yours, it means you use your own 9 yuan bought a second chicken , and sold for 11 yuan , of course made ​​a 2 yuan, 1 yuan for others of course, but also his left one yuan myself ..
