"Lady, there's nothing wrong with teaching the mantra to the rich man for her husband, right?"

Hong Tao took the princess and Lian'er back to the house, and asked the princess's opinion while narrating the mantra for Lian'er to write and record. His own calligraphy is simply miserable, in fact, the hard pen is also fucked up, so I have to let Lian'er do it for me.

"The rich man was given by the eldest brother, and he grew up in the palace since he was a child, so he knows the severity. If Da Lang is not at ease, the concubine can intercede with the eldest brother and let her go back to the palace. ”

The princess is really virtuous, she has no objection to her husband's decision, and she helps to pick up the gaps together, but the final decision is still in the hands of her husband.

"Don't ask the official family for this, I'm afraid the palace is not a good destination for rich adults. As long as she can really help her husband manage the Flying Eagle Club well, no matter how much she has the ability, it doesn't hurt to learn. However, the rich lady is a woman after all, and she is not good at asking too much for her husband, so she has to rely on her mother to explain the benefits and disadvantages to her. ”

The abacus is a small skill of carving insects in Hong Tao's eyes, this thing is very useful, but it is not qualitatively helpful to the country, anyone can learn it. But with his character, he will never give people benefits for no reason, and he has to try to do something as an equivalent exchange, otherwise he will feel uncomfortable from the heart.

“…… The rich adult is still a marriage match, or the concubine will go to beg the mother, and Lang Jun will take her in......" After listening to Hong Tao's concerns, the princess thought so, but her way of dealing with the problem was very distinctive and thorough.

"No, no, there are already eight people in the house, and the ninth one will have to add another expense. The rich man is here to help our family make money, so let her do the best job. ”

For his wife's generosity, Hong Tao didn't feel half gratified. As the saying goes, there must be something hateful about the poor. The princess is in the main responsibility of the previous colt, but she herself is not without any problems. Being too weak and too magnanimous is sometimes a shortcoming, and it is still a very fatal shortcoming.

The abacus mantra is divided into four parts, addition, subtraction, multiplication and division, of which division is divided into at least two kinds. Hong Tao only learned addition and subtraction, multiplication was taught by himself in the extracurricular interest group, and he had never learned division at all, probably the meaning was understood, but the formula was no longer remembered.

But that's not too much of a problem, as simple calculations are concerned, addition and subtraction alone are almost enough, and multiplication, which is beyond the scope of everyday use. No matter how complicated the calculation problem is, you can only use a pen to calculate, anyway, it is definitely not reliable for him to push the abacus division formula backwards.

In fact, as long as Hong Tao himself doesn't mention it, the princess, Lian'er, and Fu Ji can't think of division at all, and the mantra of addition and subtraction alone has already made them intoxicated.

However, whenever one suddenly comes into contact with a new thing with obvious benefits, people will inevitably ignore its shortcomings, and it will only be slowly figured out after long-term use.

Now the three women are in a state where they can't think of anything, they only know how to pull the abacus beads according to the formula, and even the posture of each finger has to ask the colt again and again whether it is correct, for fear that a certain action is irregular and affects the calculation result.

Hong Tao is not hypocritical with them, he will answer when he asks, learn how he wants, anyway, he can pull it anyway, even if he only uses a finger pestle, as long as the mantra is not used wrong, the result is the same.

"Today's competition with the doctor of the Academy of Mathematics is all up to the rich man, don't be nervous, the rich man is no worse than those doctors in terms of the number of techniques, but now with the help of the abacus, he will be able to win a big victory."

The reason why the abacus is a magical tool is not all about the convenience of calculation, and one thing is also very important, that is, it is very simple to learn. As long as he is a person who can count, even if he can't read, he is no slower than any mathematician by just relying on rigid formulas.

In fact, the root of this is not how magical the formula is, it is the crystallization of the knowledge of countless mathematicians for thousands of years. When using a mantra, it is equivalent to a large number of mathematicians of the past standing behind it, and it is strange if you don't win.

In order to make himself look more magical and mysterious in the eyes of the students and teachers of the Arithmetic Academy, Hong Tao decided not to play in person, but to replace himself with Fu Ji. This female official really didn't rely on luck to get to the top, her memory is surprisingly good, and her hard work has thrown herself off several streets.

In just over two days, she almost didn't eat or sleep and practiced with the abacus that belonged to her, and in terms of the speed and accuracy of pulling the abacus beads, she was already a little bit of a catch-up with herself.

It doesn't take much, as long as she is given another half a month to practice, then it will be necessary to reconsider the question of who is the master and who is the apprentice. It's a pity that Hong Tao will never give her this opportunity again, and the master in the future will only use his mouth but not his hands.

"The big officials must no longer be commensurate with adults, Ji can't stand it. Since the day before yesterday, Ji has been a student of the great official, and in a few days he will write a document with the eldest princess, and in the future, he will be the head of the family with the eldest official and the eldest princess. ”

At this time, Fu Ji and two days ago were not alone at all, without that arrogance, they were replaced by full of respect, their posture was really low, and they all planned to sell themselves to the Horse Mansion as a servant.

Of course, it is not a slave, this kind of contract is more like an employment contract in later generations, only the right to use but not the property right, and there is still a period of use and remuneration. If there is an irreconcilable conflict, the contract can be terminated at any time after the government referee.

"Does the official know about this?" Hong Tao is still quite satisfied with such a helper, her ability is not inferior to that of any professional shopkeeper, and she is relatively more reliable.

But there is one issue that has to be considered, and that is her identity. So far, Hong Tao has not finally determined whether Fu Ji is suspended from her post in the palace, or whether she was rewarded by the emperor to the Horse Mansion, or simply a detective sent by the emperor.

"The eldest princess will ask the official family for Ji's palace registration, and there will be no extraneous branches."

Fu Ji has actually answered this question very clearly, no matter what her previous identity was, once the palace registration is in the hands of the princess, then she has nothing to do with the royal family. It is no different from those palace maids who were released from the palace, at most they have had the experience of serving in the palace.

"Just because of a little abacus skill?"

Hong Tao felt that Fu Ji's choice was a bit hasty and hasty, and he still had a lot of skills that he hadn't revealed, compared to the abacus, those were the real skills. But as soon as she got an abacus, she surrendered, which is a bit of a punch on cotton, which is not enjoyable.

"In Ji's opinion, the power of abacus is comparable to that of arithmetic, if it can be used throughout the business and Jia Gong in the future, how can it be a small skill?"

Fu Ji refused to agree with Hong Tao's statement, even if she was facing the inventor of the abacus, she was unwilling to admit that this was a small skill of carving insects, and she had to fight for it.

"Well, you're not afraid of death, and I don't care about burying one more, I really don't regret it?" Hong Tao really didn't want to argue with this somewhat dead-eyed woman, her thinking pattern was not on the same line as herself.

"It's a blessing to be able to get the stunt of the big official." Fu Ji's answer was quite crisp and proud.

"It's too early to say whether it's fortunate or unfortunate, but I hope it's as you think......"

Seeing that another innocent person was about to be involved in his own whirlpool, Hong Tao couldn't save him even if he wanted to. The matter of rice sac flower paste is still top secret, no one knows except herself, and she can't tell her a little, and in the end, whether she is lucky or not can only depend on fate.
