Where is the dollar?

Three people stayed in a hotel, and the price per person per day was 10 yuan. Everyone paid 10 yuan, and the total was the boss 30 yuan. Later, the boss gave a discount of 5 yuan and asked the waiter to return it to them. As a result, the waiter embezzled 2 yuan, and each of the remaining 3 yuan returned 1 yuan, which means that each person spent 9 yuan's money. Three people spent a total of * * * 27 yuan, plus

The waiter is corrupt. 2 yuan always ***29 yuan. Where did the dollar go? ?

Second, mathematics common sense?

People call 12345679 "Leak 8". This "number without 8" has many surprising characteristics, such as multiplying by multiples of 9, and the product is actually composed of the same number. People call this "uniform". For example:?

12345679*9= 1 1 1 1 1 1 1 1 1? 12345679* 18=222222222? 12345679*27=333333333? ……? 12345679*8 1=999999999? These are all 0 times to 9 times of 65438+9. ?

And 99, 108, 1 17 to 17 1. Finally, the answer is:? 12345679*99= 122222222 1? 12345679* 108= 1333333332? 12345679* 1 17= 1444444443? …? … 12345679* 17 1=2 1 1 1 1 1 1 109?

This is also called "uniform".

Third, a brief history of mathematics.

Mathematical magician

198 1 One day in summer, India held a mental arithmetic competition. The performer is a 37-year-old woman from India. Her name is Shagongtana. On that day, she will compete with an advanced electronic computer with amazing mental arithmetic ability. ?

The staff wrote a long list of 20/kloc-0 bits, asking to find the 23rd root of this number. As a result, it took Shagongtana only 50 seconds to report the correct answer to the audience. In order to get the same answer, the computer must input 20,000 instructions, and then calculate, which takes much more time than Shagongtana. ?

This anecdote caused a sensation in the world, and Shagongtana was called a "mathematical magician".

Mathematical humor jokes? 100 integral?

After the final exam, Xiao Liang went home and said, "I got 100 this time." Mom and dad are very happy after hearing this. ? Xiao Liang went on to say, "It means that the two doors add up 100 points." Dad will hit when he hears the hand-waving, and his mother advises him: "Even if you get 40 points in Chinese, you should get 60 points in arithmetic. There is always a level! " Xiao Liang said indignantly, "Mom, it's not that algorithm! The language is 10 and the arithmetic is 0. Isn't it 100 when added together? ?

How old is little Li Jing?

An uncle asked how old Smarty was, and he said, "If I subtract my twice age three years later from my twice age three years ago, it is equal to my present age? ?

Cross the bridge?

Is there an A today? b？ c？ d？ At night, four people will walk from the left to the right of the bridge. Only two people can walk on this bridge at a time, and there is only one flashlight. You must cross the bridge with a flashlight. The fastest time for four people to cross the bridge is as follows: a? 2? Points; B, is it? 3? , integral; C, is it? 8? Points; d？ 10. Fast walkers have to wait for slow walkers. How can I get there? 2 1? Integral? Let everyone cross the bridge.

The story of a mathematician when he was a child?

Euler (1707 ~ 1783)?

Euler, Swiss mathematician, member of the Royal Society. ? Euler was fascinated by mathematics since he was a child, and he was an out-and-out mathematical genius. /kloc-became a student of a prestigious Basel school at the age of 0/3,/kloc-obtained a master's degree at the age of 0/6, and was promoted to a professor at the age of 23. 1727 was invited to work in the Academy of Sciences in St. Petersburg, Russia. Overwork blinded him. However, it didn't affect his work? . Euler has an amazing memory. Hydrogen theory 177 1 a fire in St. Petersburg reduced his large collection of books and manuscripts to ashes. With his amazing memory, he dictated and published more than 400 papers and many works. Euler, a mathematical superstar in the 0/8th century, is in calculus, differential equations, geometry, number theory, variational theory and so on. He has made great contributions in various fields, thus establishing his position as the founder of variational method and the pioneer of complex variable function. At the same time, he is also an excellent popular science writer, and his popular science books have been reprinted for 90 years. Euler is the most prolific mathematician ever. It is said that his precious cultural heritage was enough for all the printing presses in St. Petersburg to be busy for several years at the same time. ?

As one of the four mathematicians who have made the greatest contribution to mathematics in history (the other three are Archimedes, Newton and Gauss), Euler is known as "Shakespeare in mathematics". ?

Famous sayings of mathematical celebrities?

Mathematics is the queen of science and number theory is the queen of mathematics. Gauss?

As long as a branch of science can raise a large number of questions, it is full of vitality, and no questions indicate the termination or decline of independent development. -Hilbert
