Say goodbye to the children, McGonagall and Luna walked side by side for a while in the Aden Square under the glory of the setting sun. Amy and the ugly duckling were playing hide and seek in the front, and the silver bell-like laughter spread throughout the square.

Luna and McGonagall said that the decimal and nine-ninth multiplication tables caused a sensation and heated discussion in the mathematics of Luodu. The mathematicians of the Los Angeles Empire were verifying the feasibility, because this cryptographic algorithm was used to unify the mainland currency. It has been applied once, which is the result of the collision of different mathematical civilizations of mathematicians of all ethnic groups.

However, in addition to the application of currency, the Los Angeles Empire still maintains its own hexadecimal arithmetic tradition, just as the elves' calculations still follow the hexadecimal.

Although the decimals were collected by mathematicians all over the continent, they have not been valued and extended. In their view, the decimal algorithm is more complicated and difficult to understand, and even re-converted to hexadecimal. Calculation.

It can be said that the mathematicians are caught in the so-called traditional **** and strange circles. They never thought of starting from decimal. This also led to this most advanced and simple algorithm. After several decades, it is still only used in the monetary system. .

And McGonagall's nine-ninth multiplication table can quickly calculate the multi-digit multiplication, as long as you are skilled, even children can easily use it.

This subversive algorithm and discovery is undoubtedly an earthquake for the entire mathematical world. The simple arrangement, including all single-digit multiplications, is enough to solve all the single-digit multiplication problems, enough to easily cope with life. Many questions about currency.

If you can extend it to tens and hundreds digits, the speed and efficiency of the operation is definitely far beyond other hexadecials, and even the possibility of three-digit multiplication is provided, which is almost impossible to achieve in hexadecimal. Even Father Field can only do the simplest three-digit multiplication.

Therefore, during this period, the mathematicians of the Los Angeles Empire gathered in Luodu, and they were discussing this issue. Whether to abandon the hexadecimal notation and comprehensively reform into a decimal number also set off several large-scale debates.

The reformists saw an infinite future in decimal, while the old school thought that decimal is just a false proposition that has not been verified. It has been said that no one has been describing it for decades, and now a dumb fellow throws a random one. The so-called multiplication method is actually unreasonable to subvert the tradition that has been passed down for thousands of years.

McGonagall listened to Luna's description, and couldn't help but smile on his face. He didn't expect that he would throw a copy of the multiplication method, which caused such a sensation in the world.

"Mr. McGonagall, I wanted to go to see you today. I am going to reform the decimal and verify the promotion of multiplication. My grandfather is standing on the side of the reformist, so he wants to invite you to a trip. Luodu, explain to everyone the origin and feasibility of these things.” Luna stopped and looked at McGonagall seriously.

"This may not work. Math is just a hobby for me. I can't leave the restaurant and go to Luodu to tell them about the multiplication." Maggie smiled and shook his head, looking at the peace sculpture in the middle of the square in the distance. Two white pigeons landed on the olive branch and said indifferently: "It is a mission for me to bring a wonderful gourmet experience to the guests."

Luna looked at McGonagall's side face, and the golden afterglow was scattered on him, like a layer of faint sands, yes, this is a genius mathematician, but even a talented chef, compared to Counting the world, it’s a pity that such a chef is less, and some are embarrassed: "I am sorry, Mr. McGonagall, I have made such an unreasonable request to you."

"Nothing, Miss Luna's grandfather is committed to promoting the popularity of arithmetic. It is a great educator. If he has any needs, he can always ask me." Maggie smiled and shook his head, but it wasn't that he forced it, just If he drops the restaurant and goes to Luodu, the system is estimated to be crazy.

Moreover, it was hard to come from Luodu to the city of chaos. He didn't want to go back there so quickly, standing in the middle of the whirlpool, and the ghost knew if it would fall.

At this time, correspondence is naturally the best choice.

"Thank you, I will pass on what you mean to him." Luna’s face reappeared with a smile. Although Maggie didn’t want to go to Luodu, if he was willing to continue to provide his ideas and ideas, it would be good. The news.

The two continued to walk for a while, and McGonagall thought that Luna would raise some questions about the assistance of these children. She did not expect that she did not mention anything from beginning to end, which also increased his goodwill.

This girl is as clean as the white silk scarf on her shoulder. She can do good deeds, but she will not ask others how.

The sky gradually darkened, Luna said goodbye to the two, and McGee also walked with Amy toward the home. When he walked to the center of the square, he saw a row of four meters on the side near the street. The high magic crystal wall, several magicians are directing the workers to debug the installation.

"Starting tomorrow is a war." McGonagall looked at the crystal walls, and there were some expectations in the eyes. These should be the preparations for the battle for the Aden Square food list starting tomorrow. Even if, to do, of course, I hope to be closer to the front.

Back at the restaurant, there were sporadic guests at the door watching the notice. Seeing that Meg returned with Amy, he quickly asked some questions about it: "Mr. Boss, I heard that the restaurant was beaten, you are fine. What?"

"Nothing, the mob has been taken away by the Grey Temple, that is, the restaurant has suffered a little damage, but it does not affect tomorrow's business." Feeling the care of these guests, McGonagall was also moved, smiling and shaking his head.

"Yeah, the bad guys have been burned by Amy's fireball!" Amy nodded and said.

"The little boss is the best." Everyone laughed and heard that Maggie and Amy were fine.

"The boss of Mai, you see that we haven't eaten so late, or do you want to give us some food? If the new product is ready, it's better..." A bald man smiled and looked at McGonagall, behind Although it is not spoken, it is self-evident.

"Sorry, this kind of thing happened today. My young mind has been greatly hurt. I need to take a rest in a calm manner. So I need to slow down and calm down today. Please come back and open tomorrow as usual. Dish." McGonagall refused, and took Amy into the restaurant.

"This..." The guests looked at the closed door and looked at each other.

"Forget it, this time still understand the Mai boss, I just heard that when the accident happened at noon, there was a big bang in the restaurant, a group of dozens of thugs surrounded the restaurant, all kinds of snoring, = gray temple sent The army came over and suppressed it." A little old man said, turning around and leaving.

"So horrible? That's forgotten. Look forward to tomorrow's new dishes. Go ahead and queue up."

Everyone has dispersed.
