The Math Story of Grade Two Students Part One
After the death of the farm owner, he left 65,438+07 horses to his sons. In his will, he wrote, "Half for the eldest son, one third for the second son, and one ninth for the younger son.". Three sons are really annoying, but they don't know how to divide them, and there is no need to kill a horse for nothing. This is really a big deal. My father's friend knew that the two brothers could not distribute horses smoothly according to his father's will, so he came to explain that his father lent him a horse before his death, and then returned it to them first, and then returned it to him if there was any surplus after the inheritance was distributed. Everyone was satisfied with the result. Do you know how to divide it?
Finally, among the 18 horses, the eldest son got 9, the second son got 6, the younger son got 2, and the remaining 1 horse was returned to his father's friend. The problem was solved and the horse returned to his father's good friend. What a happy ending.

Bajie opened a small grocery store. One day, the little monkey came to make a catty of vinegar for his family. The little macaque came to Uncle Shi's shop and shouted, "Uncle Shi, jealous!" " "Eight quit to ask the little monkey how much vinegar to play. The little macaque said, "Not much, just one or two. "
Pig was surprised and asked, "What's the use of vinegar?" The little macaque said, "Of course!" Pig asked again, "Is one or two enough?" The little monkey said, "Not enough, let's play one or two more!" " "
Pig asked again, "Two taels is not much?" The little monkey said, "Let's play again." Bajie hit once or twice again. The little monkey said, "Give me one or two, and then give me one or two ..." In this way, the little monkey made twelve ounces of vinegar, which is a catty of vinegar.
After drinking vinegar, the pig said, "* * * A catty of vinegar is eighty cents." The little macaque unhurriedly took out eighty cents and gave it to Uncle Bajie. Pig took the money and said, "No kidding, it's still 4 cents short!" The little macaque asked, "Uncle Shi, how much is a cup of vinegar?" "
Pig Pig said, "Of course, one or two ounces of vinegar is 8 cents and 4 cents, and you should give it away. Charge 8 cents. " The little monkey said, "So, one vinegar or two is 8 cents." "Of course," Pig said. The little macaque added, "Twelve ounces of vinegar is eighty cents!" "
Pig said, "It's accurate." The little monkey said, "I gave you eighty cents." How can you say that you still need 4 cents? " Bajie was speechless, lost another 40 cents, and watched the little macaque go away with vinegar.

When Gauss was in the second grade of primary school, once the teacher wanted to have a rest after teaching addition, so he asked the students to do some calculations. The topic is:1+2+3+4 ...+96+97+98+99+100 =? I thought the students would be quiet for a while, but I was about to find an excuse to go out, but Gauss stopped me! It turns out that Gauss has worked it out. Little friend, do you know how he did it? Gauss told everyone how he worked it out: add 1 to 100 and 100 to1; Line up in two rows and want to add, that is:1+2+3+4+………………+96+97+98+99+100+99+98+97+96+……+4+3+. 38+0+10 1+1+101* * has one hundred1kloc-0/,but the formula is repeated twice. Since then, the learning process of Gauss Elementary School has already surpassed other students, which laid the foundation for his future mathematics and made him a mathematical genius.

One day, who will these lovely digital dolls "0-9" compete with? Who is the youngest? Digital baby "9" jumped out and said proudly, "Me!" Pointing to "0", he said, "Especially you are absent-minded, which means that there is no object, and you are the youngest!" Digital baby "0" blushed and cried sadly. At this time, the digital baby "1" pulled "0" and said, "Don't be sad, we are older than him together." At this time, "1" and "0" stand side by side and become "10". "9" saw it and bowed his head shyly.

A mother pig took three little pigs to buy flowers. 20 yuan, a flower, mother pig wants to buy 60 flowers. So, mother pig asked three little pigs, "We want to buy 60 flowers, one in 20 yuan. How much will that cost? " Baby Pig said, "20 times 60 equals 1200 yuan, so 1200 yuan!" The second little pig said, "No! Don't! It's two tens times six tens equals twelve tens, which is 1200 yuan!
