A strange, fun, and exciting middle school like no other is coming to the world!
The best math novel written by a KAIST brainiac and a novelist.

Mathematics Specialized Middle School is a place for gifted students in mathematics that was established 10 years after the closure of Korea Science High School.
The school begins to come alive with the arrival of its first batch of quirky freshmen.
The main characters are Jin No-eul, a computer genius and cute troublemaker; Im Pa-rang, the math god and tsundere; Heo Ran-hee, No-eul's watcher and the one who never cries even when lonely or sad; and Han Areum, a sasaeng fan of the idol group Limit.
While struggling with the math problems thrown at them every day, the children learn of the existence of the secret organization 'Zero'.
As we get closer to zero, the great secret hidden within it is revealed… .

In a harsh math education environment where the percentage of dropouts is increasing, a KAIST engineering student and a novelist met and, after three years of preparation, published a math novel for teenagers.
『Mathematics Specialized Middle School』 is a comical, lively, romantic, and mysterious math novel series that perfectly combines novelistic fun and mathematical knowledge to elicit empathy from teenagers.
Author Kim Joo-hee, who has established herself as a solid presence in the world of serialized novels on Naver, has created characters so charming and lively that they could easily form fan clubs.
Comical, romantic, and mysterious events unfold without pause around them.
The tightly packed and captivating storyline, which includes a strange love triangle, the competitive nature of middle school students, and mysterious incidents that will make you explode with curiosity, is enough to capture the hearts of teenagers.


It faithfully reflects the middle school mathematics curriculum, from prime factorization to magic squares, Fibonacci sequences, and equations, within a solid novel line, making it a good guide not only for current middle school students but also for prospective middle school students who want to experience middle school mathematics in advance.
The mathematical knowledge presented in this book is not one-sidedly taught, but rather is explained step-by-step, focusing on principles from the learner's perspective, so anyone can read it comfortably and without burden.

As I pushed open the glass door and entered, there were five laptops in the lobby.
Several children were standing in front of it, looking at the monitor.
No-eul also stood in front of an empty laptop.
There were three square boxes floating on the monitor, and numbers inside them were blinking and changing rapidly.
Looking closely, I saw that 1, 2, 3, and 4 were rotating in sequence.

Below that, there was a box to enter your name and student number, and it said, "Press Enter to determine your three-digit dorm room number." When Noeul entered the information and pressed Enter, the rotating numbers stopped.
At that moment, a new message window popped up.

─ Would you like to decide on number 121?
'The first number would indicate the floor.
The first floor doesn't have a great view, so come back!'
When I clicked the 'No' button, a new window appeared.

─ You can select the room again by solving the following problem.
The dormitory has a total of 4 floors, and 2 people are assigned to each room.
If no rooms have been assigned yet, what is the probability that you will be assigned a room on the third floor?
Noeul smiled faintly.

'Is this the math middle school?'
Since each square can contain the numbers 1 to 4, the total number of possible cases is 4×4×4=64, which is 64.
On the 3rd floor, the first seat is set to 3, so 4 x 4 = 16, 16 rooms are possible.
In that case, ×100 = 25, there is a 25% chance that you will be assigned to the 3rd floor.
When I typed 25 in the blank space, the number pad started spinning again.

Noeul pressed the Enter key again.
Then, the phrase 'Room 201, Jinnoeul' appeared on the screen.
I was going to keep trying until I got to the 4th floor, but decided to give up.
It's a waste of energy to go up and down to the 4th floor every day just for the view.

Noeul chose room 201 and headed to the second floor.

“Come out in groups and take one basket from the back.
Inside the basket, there is a rectangular block measuring 30 mm in width, 15 mm in length, and 20 mm in height.
Stack the blocks on the green board without any gaps to create the smallest cube and submit it.
“Only the first group to arrive will receive 4 points.”
Noeul, who had been feeling a bit irritated from sitting, suddenly got up and went to get the blocks.
Noeul, who had brought the blocks, sat down and muttered.
“Can’t we just stack these up to make a cube?”
“What do you mean, roughly? There’s a whopping 40,000 won at stake.”
That's right.
A scholarship of 4 points, or 40,000 won, is awarded for one assignment.
As soon as she put down the basket, Ranhee started stacking the blocks here and there.
Arum seemed to be calculating something silently, while Noeul and Parang looked at the children without saying anything.
“When you stack blocks, the width increases in multiples of 30, 60, 90… 30, the height increases in multiples of 15, 30, 45… 15, and the height increases in multiples of 20, 40, 60… 20.
But since all sides of a cube must be the same length, shouldn't we find the common multiple of 30, 15, and 20? Since it's the smallest cube, it's the least common multiple!"
As Ranhee spoke, Noeul ruffled her hair.

“Oh my goodness.
“Have you solved everything?”
“Oh, shit! My hair is tangled!”
While Ranhee was glaring at Noeul as if she was going to devour her, Areum finished calculating.
"The least common multiple is 60, isn't it? I hope I didn't make a mistake in my calculations. I tried it two ways."
Ranhee, who was worrying with Areum, looked at the sunset.
“Stop being quiet and get involved! You’re better at math than me.”
“I didn’t solve it.”
Ranhee, who was falling into a state of frustration, belatedly realized that there was a top student, Parang, in her group.
Ranhee and Areum's gaze turned to Parang.
The indifferent Parang said as he stacked the blocks.
“What Areumi solved is correct.
“To make the length of each side of the cube 60mm, stack 2 cubes for width = 2, 4 cubes for height = 3, for a total of 2×4×3 = 24 cubes.”
Ranhee and Areum's mouths dropped open at Blue's explanation.
“You weren’t even calculating.”
“I did the math in my head.
“I finished calculating, but I didn’t tell you because you guys kept solving it.”

After a while, Jeong Tae-pal, the club manager, entered the classroom.

“I will explain about opening a club.
There are a total of 21 clubs currently scheduled to open.
A simple test will be used to determine whether or not the club will be approved.
“The test items are designed to combine the characteristics of the club with mathematics, and group members can solve the problems together.”
The classroom was in an uproar.
It was another test.

“If you check the notice on the website, the test date, location, and required materials for each club will be announced.
Any club that fails the test will be automatically disbanded.
“That’s it.”
When Jeong Tae-pal left, No-eul became dazed.
I didn't know that creating a club would be this difficult.
The other children also got up and grumbled.
Noeul, who returned to the classroom, stared at the blue with a gloomy expression.
"why?"
Noeul explained the test to Parang.
“You have to pass a test to get permission to open a club.
“I think it’s probably a math problem.”
“I guess I’ll just have to pass.”
As Blue spoke indifferently, Noeul's expression became one of enlightenment.
Jeong Tae-pal clearly said that they should solve it 'together', and there was blue in the blue sunset.
