There is no doubt that algebra evolved from arithmetic. As for when the subject of algebra was born, it is not easy to say clearly. For example, if you think "algebra" refers to the solution of bxk=0

That is now.
So, in fact, in the development of human mathematics, the concept of algebra has already appeared.
Jieyu has been shackles for a long time, and it is just a little bit closer to breaking through.
The person who gave her guidance was naturally Liu Zheng.
Liu Zheng chuckled: "That's right."
Jieyu said excitedly: "Then geometry is space?"
Liu Zheng was startled again and nodded in confusion.
"I understand!"
Then......
Jieyu picked up his pile of files again, slammed the door and left.
I......
Liu Zheng touched his nose, that's it?
He laughed dumbly.
He quite liked the busy days these days. These north-gazers would wait for him every day, explaining this and that, many strange questions, so there were many strange answers to them.
It's really good...
Teaching and preaching makes people feel comfortable.
"Haha, Liu Zhizhou got up very early today!"
Liu Zheng got up and went out to wash up. Wang Chao had already arrived.
Liu Zheng smiled and said: "Mr. Dean, today is..."
Wang Chao laughed, not knowing whether it was true or not, and said leisurely: "I feel very relaxed these days when Liu Zhizhou is here! It would be great if Liu Zhizhou can always be in the academy."
ah?
Liu Zheng smiled bitterly.
This cultural man's words are just different. Does this mean he thinks he has stayed in the academy for too long? That makes him a dignified dean without any sense of existence?
This is so funny.
On the cloud, he wished he could lock himself away for a month so that he could not catch up with Xie Tianyao's birthday when he returned.

How good is your pen? Naturally, these books must be signed by the dean, otherwise Liu Zheng is afraid of my name and cannot convince the public!"
Wang Chao's eyes lit up: "Is this true?"
Liu Zheng smiled and nodded: "Of course I take it seriously."
People have suffered a loss, why should they be allowed to eat another candy? Liu Zheng's understanding of people's hearts has reached its peak. He knows that Wang Chao will definitely feel unhappy if he forcibly cooperates with the academy. At this time, he cannot
Instead of suppressing him too much, he wanted to raise his status, and books were the best opportunity. People in this era care most about reputation, but Liu Zheng no longer needs these.
What can I do if I sign it for him?
"Hahahahaha, Liu Zhizhou is so awesome, so good! Then I have to rush to adapt it even if I forget about food and sleep!"
Wang Chao laughed happily.
at this time.
Suddenly there was a rush of footsteps, and when I looked back, I saw Qin Changfeng with an anxious look on his face.
Something happened?
