1. Mirror question
Pleasant Goat and Boiling Goat saw a mirror hanging on the tree. In the mirror, Big Big Wolf pointed at a clock. The time on the clock was 10:50. Big Big Wolf said: "Do you know the real time? If you don't know how to do it, you are fools. If you know how to do it, you sheep are still fools!"
Boiling Sheep thought for a long time and said : "Isn't the time you see in the mirror 10:50?" Pleasant Goat said: "The object seen in the mirror is opposite to the actual object." Boiling Goat said: "Isn't it 2 o'clock? "What about 20 minutes?" Pleasant Goat said, "No. The actual time and the time in the mirror add up to 12 o'clock." Fei Yangyang also understood and said, "I understand, the actual time is 1:10." /p>
2. A few horns
The Pleasant Goat and the Boiling Goat walked for one kilometer and reached the road down the mountain. They saw another piece of paper with three equilateral triangles drawn on it without crossing. How many angles were there in it and how many right angles were there? Then Feiyangyang said: "This is not simple." Pleasant Goat said: "Each triangle has 3 angles. If there are 3 triangles, 33=9, there are 9 angles. An equilateral triangle does not have a right angle."
3. Multiplication formula
The Pleasant Goat and the Boiling Goat walked another kilometer. They saw a piece of paper that said: "When you see this piece of paper , you just have a good sleep, because this is your last sleep. What is 45 times 11?" Feiyangyang said: "It's not easy! Calculate 45*10 equals 450 first, and then add it. 45 is equal to 495!" Then Pleasant Goat said: "There is another simple way, 4 5 equals 9, put 9 between 4 and 5, it becomes 495!"
4. The rope has How long
Summer is here, and mom and dad take Xiao Cong to the mall to buy air conditioners. After choosing the air conditioner, Dad asked the salesperson to tie it up. Unfortunately, the salesperson ran out of rope. Xiao Cong volunteered to go to the service desk to get the rope.
Xiao Cong trotted all the way and arrived at the service desk. He said politely: "Hello, uncle! Please give me a 2 cm long rope. I want to tie up the air conditioner." The uncle ate a piece first. Shocked, and then said with a smile: Are you mistaken? What can be tied with a 2cm long rope? It’s a 2-meter-long rope! "Xiao Cong embarrassedly took the rope and ran back. He thought: That's right! 2 centimeters is only as wide as two fingers, which is too short, and 2 meters = 200 centimeters! No wonder my uncle laughed at me!
Children, you can’t be careless in mathematics. When we understand the unit of length, we must connect it with life, and we must not just imagine it. You see, Xiao Cong made such a big joke because of this. Don’t imitate it. Hey!
