Mathematical Breakthrough (6)

The dazzling array of wands puzzled the members of the math team. Some wands are surprisingly short, some are longer than arms, some are finely crafted and engraved with patterns, and some wands are just a small stick, which keeps their eyes busy.

Suddenly, an old man with a wand came up and said, "Have you measured your arm?" The math player shook his head and said, "No,no." Grandpa said, "Let me measure your length quickly, or you won't find your favorite wand." Grandpa said, and went to find the youngest Feifei.

Feifei obediently stretched out her arm. Grandpa measured it for a long time and said, "you are young and suitable for making a lovely wand." Look for it yourself on the right side of the counter. When you see your favorite wand, pick it up, say,' I want you to be my friend', and then answer the math problem spit out by the wand. "

Feifei walked to the right of the counter, picked out the lovely wands that happened to be half her arm, and finally picked out a sky-blue wand with white clouds printed on it, which happened to be made of poplar and lotus that Feifei liked. Feifei said to it, "I want you to be my friend." The wand glows, and it says, "Xiaohong caught ten kinds of fish, including carp, crucian carp and grass carp." Xiaohong said to her classmates, "Take any three fish, at least one carp." How many carp will there be? "Feifei thought," if this carp is less than eight, then I won't take three and it's all crucian carp and grass carp. "There must be eight carp!" Feifei didn't dare to delay. She quickly said to her wand, "There must be eight carp!" As soon as the voice fell, the wand took him to the counter and miraculously said, "Pay here. I like to be friends with you. "

Feifei waited for his team here, only to hear a "sloped" sound. Brother Jiacheng came, and then all the players "changed" here. Feifei said, "Let's pay quickly!" In the end, 20 coins bought 1 1 wands, and the players enjoyed their teammates' wands. Everyone was happy.

The white clouds are blue petals of cordate telosma made of Sophora japonica, the horses are made of holly and narcissus stamens, Jiacheng is made of bamboo leaves of diamond poplar, the hairy ones are sun petals made of black thorn wood, and the petals of Daphne and Tulip are made of morning. Everyone's wand is different, but when you are happy, the problem comes out. How does the team get out of this wasteland?
