请写出计算方法
Or think about the loss and gain at every point of the occurance of a number or trade.
19 value of the shoe no gain no loss
25 price of the shoe no gain no loss
50 fake bill no value
50 from the neighbor gain
shoe and 25 to the buyer, loss 19 and 25
50 real bill returned to the neighour, loss 50
hence the loss would be 19+25+50, the gain is 50
In total his loss is 19+25+50-50=44.
 
-44 块.
