任何人都可以快速的計算出結(jié)果,如果他知道了運算的規(guī)律.
讓你的朋友在黑板上寫下任意一個五位數(shù),然后你在下面也寫下一個五位數(shù),要求這個五位數(shù)每個數(shù)字對應的上面的數(shù)字相加等于9.
讓你朋友在你寫的五位數(shù)下寫第三個五位數(shù),然后你以相同的方法寫下第四個五位數(shù).他寫完第五個數(shù)字后,你畫一條橫線在下面,然后快速計算然后寫下總數(shù),你甚至可以從左到右寫出答案.
你怎么做到的呢?你從第五個五位數(shù)中拿走兩個數(shù)字,然后在你的答案前面加個2,有趣嗎?
個人翻譯,不懂的地方可以問我^-^

Anybody can learn to count fast if he knows the secret of following trick.
Ask your friend to write any five-figure(五位) number on the blackboard. Then you write your five-figure number under it. You choose your figures so that each one with the figure above it will make nine.
Tell your friend to put a third five-figure number under your number. Then you write a fourth number in the same way. After he has written the fifth number, you draw a line under it and quickly write the sum(總和). You may even write it from left to right.
How do you do it? You take away two from the fifth number and put 2 in front of your answer. Is it interesting?
