The days of drawing cards at Hogwarts

Tom was also nearby and listened to the question.

This problem is quite complicated. The root of the complexity comes from the morbid currency conversion system in the magic world, where 1 gold Galleons can be exchanged for 17 Silver Sickles, and 1 Silver Sickles can be exchanged for 29 Copper Nuts.

Tom really doesn’t understand. Why do you choose two prime numbers as the conversion unit? Isn’t the decimal or twelve decimal system better? Even if the magic world wants to show its unique characteristics, why not choose the most magical number 7?

?

Hard to understand.

However, we can still make a rough judgment. The complete collection of Lockhart is worth 35 Galleons, and the 10% discount is 31.5 Galleons. Whether you want change depends on whether the remaining book fee is enough for 2.5 Galleons.

3 Galleons and 9 Sickles. Judging by my feeling, even with a 20% discount, it is still greater than 2.5 Galleons, so that person needs to make up money.

But then Tom was a little dumbfounded: I'm afraid he needs to calculate carefully how much money he will need to make up.

Hermione:......

She looked like her calculations were overloaded. She was down for a while. In the end, she rolled her eyes and her breathing became short, but she still couldn't get any results. Finally, she took out a pen and paper and did some calculations by hand.

Come to the conclusion: "367.5 Nats, which is 12 Sickles and 19 Nats?"

Lawrence took out something like a typewriter and started tapping away. After a while, he nodded, "It is indeed the money to erase the odd change."

Seeing that both Tom and Hermione were looking at the machine, he smiled sheepishly, "This is a calculator. To be honest, I deliberately made things difficult for you with the question just now. We don't usually have something like this in our store."

Fancy discounts..."

Then he showed Tom and Hermione how to use the calculator. The calculator was covered with metal gears and levers, which gave people an unfamiliar feeling.

The method of use is not complicated. There are three glass rollers on the left side of the calculator, which correspond to the gold Galleons, Silver Sickles, and Copper Nats paid by the customer. There are five rollers on the right side. Enter the price of the book here. The first three

is the currency unit, the penultimate one is the discount amount, and the last one is confirmation. After pressing confirmation, you can enter the price of the next book. Pressing it twice means that all book prices have been entered, and the machine will

The calculation will start. There are also three rollers at the bottom of the machine, where the change is displayed.

After reading this calculator, Tom and Hermione had very complicated expressions: there were so many flaws that they didn’t know how to complain about it.

"So if you enter any number incorrectly, you have to enter them all again, right?" Hermione discovered the key to the problem.

Lawrence:…

"You actually got the correct answer just by calculating in writing?"

Hermione: "It's nothing, I'm just sensitive to numbers."

Tom & Laurence:…

Lawrence coughed twice, "Actually, because it's too troublesome to calculate, Flourish and Blotts Bookstore basically doesn't offer discounts. I'll give you a few more questions."

So Mr. Lawrence asked a few more questions. This time, since there was no discount involved, Hermione could calculate much faster, even faster than Lawrence could type on the calculator.

"Merlin!" Mr. Lawrence scratched his thin hair. He felt that Hermione was simply a monster. It was incredible.

"She is the top student in our grade." Tom reported Hermione's identity.

Lawrence's eyes flickered between the two of them for a while, and without saying anything else, he took Hermione to sign the contract.

After Hermione signed the contract, Lawrence gave each of them a vest with the Flourish and Blotts trademark. Tom and Hermione were considered part of the Flourish and Blotts Bookstore.

Hermione was in charge of the cashier at the front desk, and Tom was in charge of restocking the bookshelves.

For Hermione, the work in the bookstore is very leisurely, and there are not many customers on weekdays. Many people just come in for a walk and then go out. This means that Hermione does not have much work. Her working hours are also normal.

, which happened to be the bookstore's opening hours: nine in the morning to five in the afternoon. Tom came an hour earlier than her to sort out the shelves. Hermione worked five days a week and earned ten galleons a week.

Tom is a little busier. He needs to take out the new books from the warehouse and put them on the bookshelf. At the same time, he needs to put the few books on the bookshelf in small books, and then go back to the warehouse to make up for them. However, because there are not many books sold, they are not popular.

There were only a few books, so Tom became proficient after just a few trips.

Soon, Tom finished his work and began to fish confidently. He sat on the small stool next to the cashier, lying on the counter with his hands, tilting his head and looking at Hermione.

Hermione had long been out of work - the last customer had checked out and left a quarter of an hour ago. At this time, she was reading a best-selling book called "Breaking with the Ghost" with gusto. She felt that someone was there.

Looking at her, as soon as she put down the book, she saw Tom resting his head on the cashier and staring straight at her.

Hermione's face turned red and she slapped the book directly: "What are you looking at? Go and do your work!"

"But my work is done."

"Then find a book to read!"

"Is this book good? This author's books have been selling very well recently."

When talking about books, Hermione opened up her chatterbox and began to talk endlessly about her thoughts after reading. Tom listened quietly next to him, as if he was listening to a stand-up comedy. But after listening for a while, he also had the idea of ​​​​looking for something.

Check out this Lockhart book for ideas.

So he looked for a Lockhart novel and took a look at it. It didn't matter, Tom was also attracted by the stories in it. Lockhart's stories are all "based on real events", and the writing is good, so naturally

Many people buy it.

The first day of work ended like this. At five o'clock in the afternoon, Tom and Hermione left Flourish and Blotts Bookstore after cleaning up. Hermione walked through the Leaky Cauldron to catch her father's car home, and Tom went back to Orly's.

Vander's Wand Shop.

Back at the wand shop, Mr. Ollivander also finished the work at hand. He stood up with a smile and handed Tom a thick notebook and a half-person-sized box.

"You should read this first in the next two days and combine it with what's in the box."

Only then did Tom realize that the big book was an illustration of wand materials, and the box contained samples of various materials. Mr. Ollivander handed the illustration to Tom and left. However, Tom did not return to the dormitory immediately, although Ollivander

Mr. Vander didn't say anything, but he still cleaned the store a little, sweeping the floor and wiping the counter: this is an apprentice's obligation.

After that, he moved into the house provided by Mr. Ollivander. The house was just behind the wand shop. It was small and the interior decoration was very simple: there was only a bed, a chair, a table and an oil lamp.

.There is also a small cubicle next to the house, which is a two-in-one bathroom and toilet.

This will be Tom's residence for the next two months. Although the room is simple, it is very clean, and the various furniture give it the right feeling.
