My and Her Perfect Diary

As the security personnel slowly opened the entrance curtain, a vibrant airflow rushed into the scene, bringing countless curious and expectant eyes. The wisdom of the old village chief was once again revealed. He cleverly balanced the popularity of each booth to ensure that every contestant could show themselves on a fair stage. Otherwise, the booth of Little Star would have been surrounded by enthusiastic fans of the Su family father and daughter, becoming a unique landscape.

Xiao Xingxing, it's really you! I'm so happy to see you! A young woman dressed fashionably and smiling walked through the crowd and walked straight towards Xiao Xingxing, her eyes sparkling with excitement and joy. She is a loyal fan of the Su family and daughter, and one of the first audience members to arrive on this special day. Her words were like a spring breeze, making Xiao Xingxing feel unprecedented warmth and support.

Uh... Hello, sister! Xiao Xingxing responded shyly, with a hint of childishness and surprise in her voice. She looked up at this beautiful woman who was about 20 years old and had outstanding temperament, and her heart was filled with gratitude and appreciation. At this moment, she seemed to see herself and her father Su Yunze working together on the stage and gaining recognition. That persistence and dream were infinitely magnified at this moment.

Zeng Xiaoxian, who was standing by, couldn't help laughing when he heard the name "Su's father and daughter fan", and muttered to himself: "It seems that my 'pickle army' still needs to be expanded!" Then, his "grand plan" was met with collective eyerolls and ridicule from a group of friends in the Love Apartment, adding a bit of relaxed and joyful atmosphere to this tense and exciting game. Under a dreamy starry sky background wall, in a high-end toy store shining with warm lights, a burst of crisp and pleasant laughter came - "Hehehe, my little star baby, your laughter is brighter than the stars!" This warm shout instantly made the beautiful sister standing by, wearing a dazzling light as if she had just walked out of a fairy tale world, feel infinite joy in her heart.

“I want this sparkling magic ball, and that dream book that can tell stories, and oh, that mini music box!” The little star blinked its eyes like the brightest stars in the night sky, and its little hands drew dreamy trajectories in the air, and every finger exuded infinite curiosity and desire for the world.

However, in such a fantasy space, there is an unwritten rule that quietly guards this purity: each visitor's wish can only be transformed into three treasures and taken away, in order to maintain balance and harmony and prevent those little guys with super powers from over-consuming the magic of nature.

The beautiful sister smiled softly, gently guided the little star's finger, and stopped at three treasures that attracted her at first sight. "This magic ball carrying the secrets of the universe only costs ten stardust coins; the storybook that can make your dreams come true, eight is enough; and the music box that can play the music of the stars is a treasure worth fifteen stardust coins." Her voice, like the breeze of a summer night, gently brushed every corner.

When it comes to arithmetic, Xiao Xingxing is not an ordinary person. She is not only a classmate of Wang Shanshan, the star of wisdom, Sha Junjun, the little science expert, and Guo Ruirui, the little logic queen, but also a member of the legendary advanced fully enclosed "Star Academy". Here, every step of the children's growth is imbued with the wisdom of the stars, and even the basic mathematical concepts are endowed with infinite imagination.

But when it comes to two-digit addition, Little Star's school journey has not yet touched the sea of ​​stars. Fortunately, Teacher Su Yunze, a knowledgeable and talented tutor at home, has used his wisdom and patience to plant the seeds of mathematics and logic in Little Star's heart. In addition, with her unique sensitivity and love for numbers, these three small challenges are nothing more than easy jumps between stars for her.

"Haha, the answer is thirty three star dust coins!" Little Star held a colored pencil and quickly jumped numbers on the special starry sky calculation board. Finally, he proudly announced his answer, with the joy of success flashing in his eyes.

Among the crowd watching, there were bursts of exclamations and discussions:

"Oh my, whose little boy or princess is this? He's so good at math at such a young age!"

"Haha, the charm of aristocratic education is indeed extraordinary."

"I have a cousin who won the silver medal in the National Mathematical Olympiad when he was only eight years old. He is also a rare talent. But it seems that this child is also a future star!"

"Children nowadays are really getting stronger and stronger. It seems that with good nutrition, their brains are developing rapidly."

“Maybe, but it’s more about the dreams in their hearts and the passion to explore the unknown world. Just like this little star, they illuminate every possibility with their pure hearts.”

Thus, in this world of praise and reverie, Little Star and the treasure she chose together wove a new chapter of a fairy tale about wisdom, dreams and love. In the live broadcast room woven by the bright stars, a unique "Interstellar Arithmetic Show" was quietly staged. Little Star, the brightest innocent star in the night sky, was lighting up the hearts of every audience with her light of wisdom.

"Hey, little star, here I have a fifty-dollar chip from the Interstellar Bank. You have to calculate the change carefully for these treasures in your store!" A beautiful customer wearing a star-studded long dress, who seemed to have traveled through time, showed the future currency in her hand with a smile. The three items in her hand shone with a strange luster under the light.

A flash of surprise and excitement flashed in Little Star's eyes, as if she was accepting the most mysterious challenge in the universe. Her little hand once again clenched the magic pen that seemed to connect the galaxy and a piece of paper that could record the mysteries of the universe, preparing to conduct an interstellar financial calculation.

"Oh, this interstellar merchant's arithmetic problem is really not easy!" The little guy muttered to himself, but in his mind he had already built an interstellar bridge made of numbers, connecting the total price of the goods on one side and the change on the other.

“Fifty… minus thirty-three… Well, zero minus three isn’t enough. We have to borrow strength from the 'ten' in five…” Little Star’s voice was full of the courage to explore the unknown. Her pen tip jumped on the paper, as if she was drawing a star map of the universe.

"Four minus three, there is a ray of starlight left, plus the borrowed ten, the total is... Wow, seventeen! But Dad said that we have to confirm it first." Little Star's eyes flashed a cunning, and then he immersed himself in the journey of verifying addition. "Seventeen plus thirty-three, let me see if we can get back to the original fifty..."

"Okay, okay, I found the answer, it's seventeen!" Little Star announced excitedly, as if he had just solved a cosmic mystery. The live broadcast room was immediately flooded with a sea of ​​comments of "Come on, Little Star", each sentence shining with support and encouragement.

Next, there was a carefully planned interstellar currency exchange ceremony. Little Star skillfully opened an "interstellar treasure box" filled with fine change like cosmic dust, and carefully selected a star-studded ten-yuan chip, a colorful five-yuan gem, and two coins flashing tiny electric lights, forming a perfect change picture.
