Ning Yunxi was indeed very overjoyed about this and said: "The HP-35 scientific calculator produced by the company is the world's first handheld scientific calculator, which has great significance as a milestone in electronic engineering and computers. Before that, engineers had all taken calculation rulers, including three rulers in one place."
Cao Deying was very pleased to hear her words: "My husband said that it is definitely right to give this to Teacher Ning. Teacher Ning can understand the meaning of this." It seems that Cao Deying and his wife had a deep discussion in order to give Ning Yunxi gifts.
Ning Yunxi turned around and showed his son what the calculator looked like. Several other children who had never seen the calculator surrounded him.
Leilei's little finger was pressed on the numeric keyboard of the calculator under the guidance of his mother. Listening to the sound of the bumps when the keys were pressed, the kid's little face showed a big and strange spirit. After pressing 11=, a 2-character appeared on the display screen. The children collectively exclaimed.
When the Cao family saw Ning Yunxi and the children's expressions as if they had found treasures, they praised Cao Deying one after another.
"Our sister-in-law is worthy of drinking foreign ink. It's different," said Tracy.
Cao Da’s wife said: “Of course.”
Cao Deying said to his third sister-in-law Ximin's mother: "It's Ximin's turn."
Ximin, my son didn't know where to go out today, and he hasn't returned home yet. Ximin's mother thought.
When Meng Chenxi left his home with his family, she never saw him come back, which was a little surprised.
In the evening, the Meng family said goodbye to the Cao family. When they left, Cao Deying warmly invited them: "You must all come next week's wedding banquet."
It's said it's next week, but it's the day after tomorrow, and the next day.
On the way back, Ning Yunxi talked to the children about the clothes and some etiquette they had to wear that day. After all, this banquet was different. There were many educated and knowledgeable people, including many famous scientific scholars like Dou Xiao.
It is said that Junjun's father Cai Qing is in the ranks of invitations, which means that Junjun's family will come.
In the evening, before Meng Chenhao returned home, he had heard about his son and his wife taking care of it. When he got home, he walked into the bedroom and saw his son lying on the bed, holding the clothes his mother made for him. His little head was not sure what he was thinking, and his little face was rosy and smirking.
Ning Yunxi walked into the room for the third time and reached out to his son for the wrong clothes and said, "I have said it many times. Give me that clothes and mom wash them for you. You want to use them for fun and then play with them."
Leilei shook his head and hugged his clothes tightly: Don't do it, don't do it~ I always feel that my mother will secretly throw away his clothes in a blink of an eye~
Ning Yunxi was so angry that he rolled his eyes.
Seeing that his wife was so angry, Meng Chenhao said to his son: "Mom can only wear beautiful clothes after washing this clothes."
When Leilei heard his father say this, he immediately sat up: Can you wear it?
"Hey hey hey, it's not this one!" Ning Yunxi quickly stopped the child's father and said, "I'm wrong. I've washed the two right clothes and hung them on the balcony. This one is the wrong clothes."
"What happened wrong?"
"Yes, I didn't know how to do it before. I did it asymmetrically and I can't wear it for him." Ning Yunxi said a little embarrassedly.
