In the digital kingdom, all numbers have to compete to see who is of great use and who can be king in the digital kingdom.
On the day of the game, the numbers were all talking. What do you want to ask? Of course, I mean for my own use. Everyone didn't notice that the "0" baby at the beginning of the number was omitted, and all the numbers were ignored. There are only two digital babies left in the final, one is "9" baby and the other is "0" baby.
Now the question is: Add "9" baby and "0" baby after the number 100 to see which number is bigger. "9" the baby said firmly, "My side is big." So, we put them together. After 100, adding 9 equals 1009, and after 100, adding 0 equals 1000. Indeed, this side of "9" is bigger than "0". So, the "9" baby sat on the throne.
Baby "0" ran away from home in anger. One day when Xiaohong was doing arithmetic, she couldn't work out a problem, 3× 8-24 =? how much is it? Because "0" baby left the digital kingdom, the child can't write. So all the characters in the digital kingdom went out and searched for three days and nights, and finally found the "0" baby. However, what if the "0" baby refuses to go home? Ha, the smartest scientist in the digital kingdom, Baby No.8, has an idea. It said, "Let's have a game! Baby won't go back if she loses. If it wins, it will go back with us. " After the contest between the king's "9" baby and "0" baby, "0" baby won. The original "8" baby said: "10-() =? If you have to count who is big, who will win. " 10-9 = 1,10 =10, of course, baby 0 won. "8" The baby also said, "Look, no matter which number the baby 0 stands on the right, which number is enlarged by 10 times." When the "3" baby and the "7" baby did the experiment, it was really like that, and it suddenly became 30 and 70!
"0" baby finally returned to the digital kingdom with everyone, but it was ashamed of running away from home and blamed itself for being too headstrong and not striving to be king. "9" baby became a minister.
Son, do you think "0" baby is important?
Find a small number of friends.
One day, Shu was bored at home and wanted to go out to find friends, so he sneaked out.
It came to the grass in front of the door and met the equal sign. The decimal shouted, "Who are you?" When the equal sign heard this, he proudly said, "I am the creator of every formula in the kingdom of mathematics." For example: 5×3= 15, 8+4 = 12, 4÷2=2, 20-8 = 12 and so on. I created so many numbers. Now you know who I am! "Decimal shook his head and said," You are not the friend I am looking for. " Said, and ran away.
Decimal came to the windmill village, and the wind from the windmill almost made the decimal stand unstable. At this time, he saw the greater than number and asked, "Who are you?" "You don't even know me," said the symbol of Bigger. "I'm a little famous in the kingdom of mathematics. I am greater than the symbol greater than and less than the symbol greater than! " For example, many numbers are cited, such as 5 > 2,10 > 5,60 > 59. Decimal shook his head and said, "You are not the friend I am looking for." So, the decimal is gone again.
The decimal jumped to the pond. At this time, it saw the score and asked happily, "Who are you?" The music score says, "My name is music score. I can divide a thing into many parts! " "For example, the score lists many scores such as 3/ 10, 25/ 100, 17/40. Decimal looked at the score and thought, huh? How do I feel deja vu when I look at these numbers? At this time, I ran over, saw the scores and decimals, and said happily, "So you are all here, you two are twin brothers!" " "Decimals and fractions are surprised:" Why? " You see, 3/10 = 3 ÷10 = 0.3,25/100 = 25 ÷100 = 0.25, 17/. In fact, we are all family, but our faces are different. Although we look unremarkable, the kingdom of mathematics cannot be separated from us. "Take a closer look at decimals and fractions, ah, really. If the mathematics kingdom lacks fractions and decimals, it will all become integers!
Therefore, decimals and fractions have become inseparable friends.
