A math story in Class 3, Grade 1.

Xiaoming is a child who likes to ask questions. One day, he became interested in the numbers 0-9: Why is it called "Arabic numerals"? So he went to ask his mother, "Since 0-9 is called Arabic numerals, it must have been invented by Arabs, mom?"

Mom shook her head and said, "Arabic numerals were actually invented by Indians." About 1500 years ago, Indians used a special word to represent numbers. There are 10 words, and you can write both strokes. Later, these figures were introduced into Arabia. Arabs think these numbers are simple and practical, so they are widely used in their own countries and spread to Europe. In this way, it gradually became the number we use today. Because Arabs have played a great role in spreading these numbers, people are used to calling them' Arabic numbers'. "

Xiao Ming heard this and said, "So that's it. Mom, can this be called' making a mistake'? " Mom smiled.

High school math story

The animal school held a children's song competition, with the elephant teacher as the referee.

The little monkey raised his hand first and began to recite: "I can calculate carry addition, and the digits can only be added if they are aligned." The number of digits should be aligned with the number of digits. When the number of digits exceeds ten, the number of digits should be advanced to ten. Add ten and one to count quickly and accurately. "

As soon as the little monkey finished speaking, the puppy began to recite again: "abdication and subtraction are not difficult, just align the numbers." If the single digits are small enough, ten people can borrow one. If ten people return, one will be ten, and if they return, one will be missing. How to reduce ten digits, ten digits will be reduced again and again. "

Everyone applauded their wonderful performance. Teacher Elephant said, "Their nursery rhymes make us understand that both carry addition and abdication subtraction should win the championship, ok?" Everyone agrees and applauds them.

A long time ago, the kingdom of mathematics was chaotic. The 0-9 brothers not only dominate the kingdom, but also boast of their greatest skills. The math angel was very angry when he saw this situation. He sent three little angels to the math kingdom to establish order and avoid chaos.

He smiled and said, "We are judges sent by angels to help you govern your country. I am an equal sign, and these two are' greater than sign' and' less than sign'. Whoever they speak to is greater. Whoever they point to is small. "

When the ten brothers heard that they were judges sent by angels, they obeyed the orders of God and ... and from then on, the mathematics kingdom had a strict order, and no one would violate it.
