Dad: At the Beginning, The Empress Brought Her Daughter to the Door to Force Her Marriage

After playing for a while, a light wind blew, bringing a strange floral fragrance into the bedroom.

Xuanzhu and the other four little darlings all twitched their noses, and their big dark eyes opened round.

"Wow, it smells so good!"

"It tastes a little sweet!"

"Go and see what it is!"

...

The little girls quickly got up from the reclining chairs, completely forgetting their previous exhaustion, and ran out of the bedroom quickly.

Soon they saw that several pots of new flowers appeared in the garden.

The flowers in these pots are purplish-blue, with large beds of turquoise leaves, and the flowers above are like golden stars.

And the sweet floral fragrance just now came from these flower pots.

Xuanzhu's big black eyes rolled around: "Could this be the star honey flower that Aunt Tong said?"

She remembered that when Tong Shuzhu came to deliver flowers last time, she specifically mentioned that there would be a new variety of flowers next.

Judging from the shape of these potted flowers, the little girl concluded that they should be the new flowers mentioned by Tong Shuzhu, the star honey flower.

Xuanhan likes flowers and plants the most, and pays special attention to the nature of flowers, she nodded:

"They are exactly the same as Aunt Tong said, they must be Xingmihua!"

Xuanxi squatted beside the flower pot, and her little finger counted the flowers on it:

"What a beautiful flower, there are nine in this pot alone!"

Xuanhan's beautiful big eyes blinked:

"I remember Aunt Tong also said that Xingmihua grows very fast and can double as much in three days at most."

"Why don't we count the total number of flowers here, and then count them again in three days, do you think?"

Xuanzhu, Xuanxi and Xuanyou clapped their little hands at the same time: "Okay, let's count together!"

With the arithmetic method taught by Lin Xuan, the little girls quickly counted nine flowers in each pot.

Then add all the flowers in the nine pots together to calculate a total of 81 flowers.

Xuanzhu said: "There are eighty-one flowers now. In three days, we will see if there are one hundred and sixty-two flowers."

"Yeah!" Xuanxi nodded.

Xuanhan thought for a while and asked, "Then if three days later, on the sixth day, will it be troublesome for us to count?"

The little girl thought, although they all know basic arithmetic.

But counting so many flowers first, and then adding them up one by one, seems very troublesome, and some are beyond their understanding.

Xuanzhu thought for a while, then nodded and said:

"Xuanhan is right, since you want to count honey flowers, of course there must be a better way."

"I remember that Brother Haoyu's school will teach them a way to quickly calculate a lot of numbers. If they use that method, they will definitely be able to get the most Xingmihua!"

"Hmm!" Xuanxi also remembered that Donghuang Haoyu once showed off his arithmetic, "Then let's let Daddy teach us!"

"OK!"

Xuanzhu, Xuanhan and Xuanyou nodded without hesitation.

And the little girls felt that maybe Lin Xuan's method would be better.

After all, he is the most powerful father in the world in his mind.

As long as it is the method he taught, it must be the best method in the world!

"Daddy Daddy!"

The little girls rushed into the kitchen and hugged Lin Xuan's thigh at the same time.

"Can you teach us a great method of arithmetic?"

Lin Xuan put down the kitchen utensils and looked at the four fleshy faces with a doting face: "Of course!"

Xuanzhu said, "It's better than what Brother Haoyu and his college teach!"

"Just now we counted the star honey flowers, and found that it will be difficult to count in a few days!"

Xuanxi nodded: "Yes, it's a bit difficult to calculate with the previous method!"

Xuanhan had a firm look on her face: "I believe that Daddy must have the most powerful method in the world!"

Seeing so much expectation and trust from her daughters, Lin Xuan said confidently:

"Don't worry, Daddy will definitely let you learn the most powerful arithmetic method."

Possessing the holy book of extreme Taoism, he knows that the arithmetic level of this world is not developed.

The school where Donghuang Haoyu is located is the top school in Beixuantian, but in fact arithmetic is still at a very low level.

And have the perfect dad tutorial.

Lin Xuan could immediately find a high-level arithmetic method suitable for Xuanzhu and the others to learn.

That is a must-have arithmetic artifact in elementary school...

Ninety-nine multiplication formula!

A few spirit fires popped up to control the cooking heat, and Lin Xuan came to the palace hall with four little girls in his arms.

Then he took out a piece of paper and wrote the formula of the ninety-nine multiplication on it.

Xuanzhu and the others were stunned: "What is this? It looks amazing!"

Lin Xuan smiled and said, "This is called the formula of the nine-nine multiplication. As long as you remember the above knowledge, you can calculate a lot of things at once."

"Nine-nine multiplication formula!"

When Xuanzhu and the others heard it, their eyes lit up.

"This must be very, very powerful!"

The little girls only knew that there were formulas for practicing exercises, but they didn't expect that there were formulas for arithmetic.

As you can imagine, this must be the most powerful arithmetic method in the world!

"Dad, then you teach us quickly!"

Being pestered by the little girls, Lin Xuan's father's love burst into the air: "Okay, daddy will teach you now!"

"First of all, this 'one-for-one' means that there is one flower in a flowerpot, so there is a total of one flower."

"'One, two, two' means that there are two flowers in a pot, so there are two flowers in total."

"By analogy, 'three three get nine' means that there are three flowers in each of the three flower pots, and there are nine flowers in total."

In order to make it easier for the little girls to understand, Lin Xuan specially used flowerpots and flowers as examples.

Xuanzhu's beautiful big eyes rolled around and raised her little hand excitedly:

"I see! We had nine pots of flowers just now, and there are nine flowers in each pot, that's 'nine nine eighty-one' flowers!"

Xuanxi and Xuanhan nodded: "Yes, it's really fast to use this formula!"

Xuan You bit her finger and studied it for a while, her big eyes suddenly lit up: "Oh~ that's how it is!"

Lin Xuan saw that his daughters understood quickly, and added:

"Multiplication is a simple arithmetic method derived from addition. Combining it with addition can calculate many numbers faster and better!"

"For example, if eighty-one flowers are doubled, we divide eighty-one into eighty and one, and then multiply each by two times and add up, that is..."

Xuanzhu, Xuanxi, Xuanhan, and Xuanyou thought for a while, and raised their little hands at the same time: "One hundred and sixty-two!"

"By the way, babies are so smart!"

Lin Xuan laughed happily.

These little cuties have really improved their responsiveness as they get older.

The speed of their learning is really terrifying.

As the father of these smart and cute little babies, Lin Xuan's heart is really full of pride and pride.

"Next, you should memorize the formula of the nine-nine multiplication first, and then use it more."

"Got it! Daddy is awesome!"

After Lin Xuan and the little girls finished talking, let them recite the formula by themselves, then turned and walked towards the kitchen.

Ding!

The mechanical sound of the system suddenly sounded.

"You have a quick mind, allowing your daughters to master the most important arithmetic formulas, reward: extreme swordsmanship!"
