Liu Bei led generals Guan Yu and Zhang Fei to ask Zhuge Liang to come out to help, but they never met twice in a row.

After a while, Liu Bei ignored the objections of Guan Yu and Zhang Fei and decided to see Zhuge Liang for the third time.

When I arrived at Zhuge Liang's house, I found Zhuge Liang sleeping. In order not to disturb Zhuge Liang, Liu Bei led Guan Yu and Zhang Fei to stand outside the door and wait quietly. After a long time, Zhuge Liang still didn't wake up. Zhang Fei was a little unhappy and said loudly, "What can this Zhuge Liang do? When I saw my eldest brother's visit, I pretended not to see it and slept all the time. Let me set a fire in his backyard to see if he wakes up? "

Liu Bei and Guan Yu quickly caught the grumpy Zhang Fei.

After a while, Zhuge Liang finally woke up and dressed up to see Liu Bei.

Brother, let's go home. What can such a thin scholar do? "Zhang Fei saw a thin scholar wearing a black silk scarf and a heavy crane, and he was so angry that he didn't dozen 1 come.

"If the general can count, I'd like to show him." Zhuge Liang shook the goose feather fan in his hand and smiled and said to Zhang Fei, "I will say a number first, then the general will say a two-digit number at will, then I will say another number, and the general will continue to say any two-digit number, and finally I will say a number."

"Who wouldn't!" Zhang Fei thinks it's a little simple.

"The general don't have to talk. I know now that the sum of all the figures that the general and I said is 233. " Zhuge Liang still said with a smile.

Zhang Fei thought, "How is that possible? He knew the total before I said it? See how I embarrass this Zhuge Liang! "

"Please ask Mr. Zhuge to quote us the figures." Zhang Fei had a smile on his face.

"35。"

"Then I say 37." Zhang Fei casually said a number.

"62。"

"46!" Zhang Fei really said another number without thinking.

"53。 General, can you add up all the figures you and I quoted just now and see if the total is 233? "Zhuge Liang was not nervous at all, and said to Zhang Fei with a smile.

"35+37+62+46+53, who wouldn't add this!" Zhang Fei quickly listed the formula and began to calculate.

The result is really 233. Seeing this result, Zhang Fei felt a little incredible. You don't say!

"Say it again, I wasn't ready just now!" Zhang Fei refused to accept it.

"The sum of the five numbers we returned is still 233." Zhuge Liang still shook his fan and said.

"35。"

"89。" Zhang Fei thought for a long time before choosing a two-digit number.

" 10。"

"25。" Zhang Fei hesitated for a long time for fear that Zhuge Liang would know.

"74。"

Zhang Fei carefully added up these five numbers, and the result was really 233.

"Do it again, not this time!" Zhang Fei still doesn't believe it!

Several times in a row, no matter what two digits Zhang Fei said, and finally add Zhuge Liang's number, the result is still equal to 233.

What is the reason? Is Zhuge Liang a divine man who can predict the prophet?

Looking at the puzzled look of everyone, Zhuge Liang explained: "No matter what kind of two-digit number General Zhang said, I will quote a sum that is added up with the sum quoted by the general. If the general quotes twice, I will quote twice with the general to make up 99."

"I see, Mr. Zhuge will divide the first number 35 into two 99' s, which just adds up to 100, so the result is 200. And 35 MINUS 2 is 33,200, and the sum is exactly 233! " Guan Yu soon understood the truth.

"Why don't you count off every time, but just 100? Isn't this better? " Guan Yu is a little confused about this.

"If the two reports add up to 100, I will report first, and General Zhang will probably guess that I cheated!" Zhuge Liang answered with a smile.

"Solving problems can be solved not only by force, but also by careful observation and brain analysis." Zhuge Liang smiled and said to Zhang Fei.

This time, Zhang Fei was completely convinced!
