Chapter 0005: A Detailed Comparison of Strengths Among Competitors

Luffy smiled and said, "Mom, you can go wherever you want! I just find it a bit strange. I've been studying and working alone outside for so long, living by myself is completely fine."

Luffy smiled and said, "I will report to the clinic tomorrow. I just got back today and got stuck here buying some daily necessities."

It is unclear who initiated the applause, but the enthusiastic clapping of everyone gradually merged into a unified sound

After 5 minutes, he returned home, and it was nearly 5 o'clock. Sally was preparing dinner, and Luffy put the food that Sally had instructed him to buy, including milk, beef, eggs, orange juice, tomatoes, and broccoli, into the refrigerator

I will continue with my training plan. Yesterday, I reviewed half of the latest cases and procedures from various countries, and today I need to continue. The flying knife has just hit the target, and I still need to practice.

206.5, with a 5% discount, the total after discount is 196.175, rounded to a total payment of 196.18 yuan. Jesse, the guest paid 200, and the change is 3.82 yuan

Wow, this is also possible, impressive! Everyone's faces lit up with excitement. They felt the atmosphere of being live spectators at the International Mathematical Olympiad.

Old John was the first to pay, pushing the shopping cart to the side, picked up the calculator on the table, and began to calculate slowly

"Ah, you are twisting me again. Let's have a conversation, not violence." David was taken to the kitchen by a certain lady for a thorough reprimand

Next!" Molly shouted happily

Old John over there also shouted, "The calculations are done, the price is right, Jack is impressive"

OK, you all should rest early. If there is anything abroad, call me.

"Find 0.54 yuan," Lu Fei said.

David and I praised him, agreeing that Jack is very intelligent

Seeing that all the customers had left and the new shoppers had not yet come to settle their bills, Lu Fei smiled and said to Molly and Jesse: "Since the backlog of customers has been cleared, I will head back now."

Isn't this a bit inappropriate? If I actively go to help, will the supermarket staff think I'm being a bit meddlesome?" Lu Fei asked with confusion

Gentlemen, this young gentleman is Jack, the son of Sally, the owner of the lakeside ranch located to the north of the town. He is the newly hired doctor at the clinic in town. The Chinese are all very good at mathematics, so let him help everyone with the calculations.

Sally hesitantly said: "Well, actually, it has been a long time since David and I traveled. We booked tickets to Europe and plan to stay there for about a month. We leave tomorrow. As soon as you return, we will be leaving. You won't be unhappy about that, will you"

"Alright, alright, Mom just suddenly really wants to go to Europe, to visit my friend Lisa in the UK. Come on, come on, it's time to eat. David, come over and help with the meal." A glint of menace flashed in Sally's eyes

"It's just a small matter, nothing much, as long as it helps everyone. I just returned to the town today and will be on duty at the clinic tomorrow. I hope to serve the folks in the town well," Lu Fei said with a smile, waving to those around him.

The total price is 39.46.

He turned back and loudly addressed the onlookers, saying: "Ladies and gentlemen, has anyone reviewed this? Is there any miscalculation?"

At this point, the atmosphere became even more lively, and everyone lined up one by one to follow.

After Sally and David finished speaking, they got up and went to the third floor to attend to their own matters. Lu Fei shook his head, picked up his luggage, and went up to the second floor. He entered the room and tidied up a bit. He gathered the clothes he brought home, along with the items he bought from the supermarket and the books, and organized them in the wardrobe. He placed the money his mother gave him on the bedside table.

Luffy sat at the table, looking at his mother and David with a puzzled expression

... ... ... The above omits numerous calculation processes ...

The nurse Mandy at the clinic in town was also in line to check out when she saw Lu Fei and came over to greet him. Being long-time locals of the town, they were all familiar with each other, especially since the two would be working together in the future. Mandy warmly inquired about Lu Fei's situation

Mandy said happily: "What are we waiting for? Please help everyone, I am eager to go home; the little one at home is waiting for me to return and cook for him."

Sally said somewhat unnaturally: "Why do you care where Mom goes to have fun? I just want to take advantage of being able to move and see the scenery in the distance with David. Anyway, the ranch is on the right track now, and we have Ranch Manager Richard taking care of everything for us, so there's no need to worry." After saying this, she looked at David, signaling him to speak.

Next '', after 15 seconds: '' 78.23, payment 80, Jesse will receive 1.77 yuan

"It is time to speak up, otherwise I won't have enough time to arrange things at home," David muttered

The residents who had completed their transactions did not leave; they were all watching the live math show. With approximately 20 seconds per person, the 30 individuals accumulated were cleared in just 10 minutes. Even Lu Fei had calculated his own shopping cart, totaling 330 USD.

"You received 40, how much change is it?" Jesse awkwardly touched his forehead

I know Jack; I heard he became a doctor. Let's give it a try

Most people heard it and gradually quieted down

Closing my eyes, I entered the training hall

By the way, you are of Chinese descent, right? I have heard that people from your culture are generally very good at mathematics. Since you are a university student and have attended medical school, you must be quite proficient in mathematics

Alright, you go to the room www.hetushu.com to tidy up a bit and rest early

After Luffy finished washing up and got into bed, he lay there staring at the ceiling, feeling a vague sense of unease. He understood his mother Sally's character well; she was not an impulsive person. What could be the reason for her urgent trip to Europe? Never mind, a mother’s will is beyond her child’s control. Seeing that David and his mother appeared to be in good spirits, it should not be anything serious. Let her do as she pleases.

Next, 3.99, 2.58, 9.99...

Next, after 20 seconds: 156.8, with a 5% discount, totaling 148.96, payment 150, Jesse receives 1.04 yuan in change

Mandy walked up to the cashier and shouted loudly, "Hey everyone, please be quiet, I am Nurse Mandy from the clinic, let me say a few words"

Molly and Jessie both came over to thank her; if the accounts were miscalculated today and they were given too much money, they would have to make up the difference.

Luffy smiled as he walked up to the cash register, speaking loudly to the cashier and the customers: "I am Jack, and I hope to assist everyone. Cashier Molly, please announce the prices of everyone's items one by one. I will calculate the total, and then cashier Jesse will handle the payments and change. After paying, the uncles and aunts will push their shopping carts to the side to double-check their purchases. If there are any issues, I will recalculate; if everything is fine, they can leave.

A middle-aged woman hurriedly pushed her shopping cart over.

Wow, so fast, that's amazing, but I just don't know if it's right, the crowd was excitedly discussing.

Don't worry about so much, come help quickly, how much worse can it get

Indeed, I have also considered it; it is completely excellent and truly impressive

Next '', after 23 seconds: 233.5, with a 5% discount, totaling 221.825, rounded to a payment of 221.83, and the payment for the book is 230, Jesse receives 8.17 yuan back

The middle-aged woman cheerfully paid an exact amount of 130, then counted out 7 cents for Jesse. Without checking again, she walked aside, smiling as she watched the commotion.

I haven't calculated it; adding up more than 10 items and factoring in the discounts is too difficult. However, I trust you

"Alas, David, you have worked hard." Luffy shook his head and sighed

After dinner, the couple meticulously went over important matters with Lu Fei, including the house keys, car keys, the usage of appliances, the safe keys and passwords, and other significant details. They reiterated the important points three times before finally easing up and letting Lu Fei go.

"We will depart from Reno Airport for a direct flight to London tomorrow afternoon. You will be going to the clinic for work, and we will manage on our own," Sally said

"Son, come here, sit by the dining table, I have something to discuss with you. David, you come over too," said Sally

You Huaxia people are just too modest and low-key, all being from the same hometown, who still cares about this

Everyone gradually dispersed with smiles, feeling that today was well spent, adding a bit of conversation to their tranquil lives. Mandy also smiled at Lu Fei and waved goodbye.

Molly finished counting the ten items priced at 2.99, 3.99, 6.3, 8.99, 19.99, 1.29, 26.99, 13.99, 33, 5.49, and 16.99, concluding her report

In such situations, everyone tends to feel a bit anxious, and many people gather in front of the checkout counter. If you are not buying anything, it is better to leave directly. It is not easy to come out here in this small town in the United States, as most people drive to the supermarket to purchase a week's worth of necessities. If you decide not to buy anything and just go home, it can be quite a waste of time. It is better to continue waiting in line to pay, although it is uncertain when it will be your turn.

The total amount is 136.92 yuan, exceeding 100 yuan for both the total price and the book fund. A 5% discount is applied, resulting in a total of 130.074 yuan, which rounds to 130.07 yuan

"Don't look at me, I can go anywhere. It's all your idea. Your mother also acted on a whim, suddenly saying a few days ago that she wanted to go to Europe, and she hastily booked the tickets overnight. If it weren't to see you, she might have flown out that very night." David quickly shifted the blame. He also felt that it was a bit excessive for the two of them to go out right after Jack had just returned.

Luffy pushed the shopping cart out of the supermarket, loaded the purchased items, both large and small, onto the pickup truck, and drove home

It's not bad; my mental calculation skills are indeed passable. Mainly, it was because my mother had me do a lot of exercises when I was young, which trained me.

Luffy said: "Alright then, if no one has any objections, I will give it a try." He thought to himself, as an outstanding youth of Huaxia who has received 9 years of compulsory education, am I still afraid of mental arithmetic? This is basic skill, alright... Moreover, as a newly promoted genius, my IQ has long reached 180, am I being arrogant?

Everyone was talking at once. The cowboys of the West respect knowledgeable individuals and have heard that the mathematics of the Huaxia people is quite impressive

I have calculated it; not a single point is missing. Well done, young man

The cashier made several consecutive errors in calculations, and some customers were arguing with the cashier. The residents of the town became even more uneasy, and those who had already checked out could only verify their bills once again.

First, 1.99, 3.59, 4, 5.6, 15, 1.29, 7.99, completed. Molly reported the unit prices of the goods

Luffy asked curiously, "Didn't you just travel around Southeast Asia two months ago?"

Alright, let's do it this way. Young people are quick-witted. Stop dawdling, hurry up. Come on, everyone was talking in a chaotic manner, many with smiles on their faces, feeling that they were about to witness a good show, quite interesting.
