The fourth grade is easy to get to the final exam.

1, Xiaoming's primary school math exam. When he came back, his mother asked him how he did. Xiao Ming said: "I can basically do it, but I can't work out a problem of 3 times 7." Finally, when the bell rang, I wrote 18 regardless of the willy-nilly. " Niu Niu: Mom, I want to be a mathematician when I grow up. "Well, ambitious mother!

Niu Niu: Mom, I'm going to learn calculation. You buy me snacks of 1 yuan every day, and I can figure out how much you give me a year! Professional characteristics Mathematicians fall in love.

Mathematicians and their girlfriends are walking in the park. His girlfriend asked him, "Do you really mind my freckles?" The mathematician replied softly, "Absolutely not! I was born to like dealing with decimal points. " Who is the meanest?

"You say, who is the meanest person in the world?" "Mathematicians, of course." "Why?"

"They fight for every ounce!" 2. Statisticians

A statistician who has never taken care of his children reluctantly agreed to take care of four young and active children when his wife went shopping on Saturday afternoon. When his wife came home, he handed her a note that read:

"Wipe tears 1 1 time; Tie shoelaces 15 times; Blow toy balloons for each child five times, and the average life of each balloon is 10 second; Warning children not to cross the road 26 times; The child insisted on crossing the road 26 times; I want to do it again on Saturday. " Step 3 subtract

In math class, the teacher said to a student, "How come you can't even subtract?" ? For example, there are ten apples in your house, and you ate four. What is the result? "

The student said gloomily, "I was slapped ten times!" " "4. Five hundred ducks

A male teacher said to two noisy female students, "The voices of two women are like the cries of a thousand ducks."

After a while, the teacher's wife came to visit him. One of the female students came to report it. "Teacher, there are 500 ducks outside the door to see you." 5. Possibility

I visited the weather station and saw many latest weather forecasting instruments. After the visit, I asked the stationmaster, "You said there was a 75% chance of rain. How did you work it out?" ? 」

Without much thought, the stationmaster replied, "That is to say, there are four people here, and three of them think it will rain. 6. Numbers

"Numbers don't lie," said the teacher. "If a house takes one person twelve days to build, twelve people only need one day. One hour is enough for 288 people. 」

A student went on to say, "Seventeen thousand two hundred and eighty people only need one minute, and 1,036,800 people only need 77 right angles."

Teacher: "You haven't proved this geometry problem, how can you conclude that this angle is a right angle?" Student: "I measured it with a protractor." 8. oral examination

In class, the teacher asked the students to judge right and wrong on the spot.

Teacher: "Xiao Lin, please judge." Kobayashi: "I think the answer should be? A mistake? . "Teacher:" Why? "

Kobayashi: "Because Xiaoyan answered in front? Is that correct? But you didn't let her sit down. " 9. Numbers don't lie.

"Numbers don't lie," said the teacher. "If a house takes one person twelve days to build, twelve people only need one day. One hour is enough for 288 people. "

A student went on to say, "Seventeen thousand two hundred and eighty people only need one minute, and 1,036,800 people only need one second. In addition, if it takes six days for one ship to cross the Atlantic, it takes six ships a day. Four cups of 25-degree water add up to boiling water! Numbers don't lie! " 10, Wu Zetian

In history class, the teacher asked, "Who knows who Wu Zetian is?" Student: "Wu Zetian is a mathematician. Five days later, she will be the great mathematician who invented rounding."
