The bells of Geneva Internally Academy rang with the kind of authority only an old boarding school could manage.
Not loud. Not dramatic.
Just enough to make every tenth-grade student in Class 2 sit up as if the building itself had cleared its throat.
"Math," groaned Lavi de Venta, dropping her forehead onto her desk. "Why does math always arrive like a tax collector?"
Across the aisle, Erica Lasison snorted into her notebook. "Because it knows we're weak."
Ruby, the TV-headed robot student sitting by the window, turned her screen toward them. A bright pixel face appeared, then changed to a tiny frown. "Correction: some of you are weak. I have already calculated my weakness and found it to be minimal."
"Ruby," said Tara, "you once tried to solve fractions by rebooting."
"It was a strategic restart."
Playful Zoe spun her pencil between her fingers. "I respect that. If I could reboot my brain before quizzes, I'd be a legend."
Kindness Chloe leaned over with a gentle smile. "You'd still have to study, Zoe."
"Rude," Zoe said, grinning.
At the back, Lily was arranging her pens in perfect color order, Ava was rereading the same page for the third time, and Mia was whispering to herself as if the textbook might answer if spoken to politely.
Near the boys' side, Louis Fabulous had his tie arranged in a way that suggested he believed the uniform had been designed specifically for him. "I'm not worried," he said, lifting his chin. "Math is simply arithmetic wearing a serious face."
Finn looked over. "That sentence means nothing."
"It means I'm calm."
"You're sweating," said Jake.
"I perspire elegantly."
Sam, who had been trying to hide a calculator under his desk, muttered, "I'm going to fail elegantly."
Shy Heist—who was only called that because he moved like he was apologizing to furniture—peeked at the door and whispered, "Is Mr. Hocus in a bad mood today?"
Cool Guy Ethan leaned back in his chair. "He's always in a bad mood. It's his style."
As if summoned by the insult, the classroom door swung open.
Mr. Hocus entered with a stack of test papers under one arm and the expression of a man who had personally declared war on laziness.
He was tall, narrow-shouldered, and sharp-eyed, with silver spectacles perched low on his nose. His chalk-stained sleeves were rolled to the elbows, and his shoes clicked across the floor like punctuation.
He dropped the stack on the desk.
"Good morning, Class 2."
A few students answered. A few pretended to be dead.
Mr. Hocus folded his hands behind his back. "Today, we begin the most important unit of the term."
Ruby's screen flashed: **Danger detected.**
Mr. Hocus nodded toward her. "Exactly. Algebra."
A collective groan rose from the room.
Mr. Hocus raised one eyebrow. "I heard that."
Zoe raised her hand. "Sir, respectfully, algebra has a bad reputation."
"And yet," Mr. Hocus said, "it remains undefeated."
He turned to the board and wrote in clean white strokes:
**LESSON + STUDY = 3 HOURS**
Then, below it:
**CHECK. CHECK. CHECK.**
"Three hours?" Lavi repeated. "Per lesson?"
"Per day," said Mr. Hocus.
The room went silent in the way only teenagers can go silent: not with peace, but with horror.
Erica frowned. "Three hours of math?"
"Three hours of focused study," said Mr. Hocus. "Not three hours of panic, doodling, and pretending the problem will solve itself out of pity."
Louis raised a hand. "Sir, what if one studies for two hours and fifty-nine minutes with exceptional passion?"
"Then," said Mr. Hocus, "one has not studied enough."
Ruby's screen blinked. "This is mathematically cruel."
"This is mathematically effective," said Mr. Hocus.
He tapped the board. "Listen carefully. A perfect math study routine has three key points."
The class straightened slightly. Even Ethan looked interested, though he would have denied it under oath.
"First," Mr. Hocus said, "understand the method. Do not memorize blindly."
He wrote:
**1. UNDERSTAND**
"Second," he continued, "practice until your hand stops trembling."
He wrote:
**2. PRACTICE**
"Third," he said, turning to face them, "check your answers. Then check them again."
He wrote:
**3. CHECK, CHECK, CHECK**
Finn muttered, "He really likes that phrase."
Mr. Hocus pointed the chalk at him. "Because mistakes multiply when ignored."
"Like rabbits," Zoe said.
"Like rabbits," Mr. Hocus agreed, as though this was a serious scientific comparison.
He began handing out worksheets. "You will work in groups today. I want cooperation, clarity, and no theatrical despair."
Louis lifted a finger. "What about elegant despair?"
"No."
"Pity."
Mr. Hocus read names from the list. "Erica, Lavi, Ruby, Tara, Zoe, Chloe, Lily, Ava, Mia—front row group. Louis, Heist, Max, Ethan, Finn, Jake, Sam—back row group."
Jake groaned. "Sir, that sounds like a punishment."
"It is a learning opportunity."
"That's worse," Sam whispered.
Mr. Hocus continued, "Each group will solve the same ten problems. You have one hour. At the end, I will check your answers."
Ruby's screen lit up with a digital timer. "I can help monitor time."
Mr. Hocus looked at her. "Useful."
Zoe leaned toward Erica. "We should pretend to be brilliant."
"We should become brilliant," Chloe corrected softly.
"See? That's why you're the kindness one."
Chloe smiled. "It's not a title."
"It is now," said Tara.
The worksheet landed on Erica's desk with a dry slap.
She glanced at the first problem and made a face. "This is not math. This is a threat."
Lavi picked up her pencil. "Let's survive it."
---
The first twenty minutes were almost peaceful.
Almost.
Ava and Mia were whispering through the first set of equations. Lily had already completed two problems and was checking her work with such concentration that her eyebrows had practically become a second pair of glasses.
Ruby rotated her screen to show a neat list of steps.
"Problem one," she announced, "is linear. Problem two is a trap."
"It's not a trap," said Tara.
Ruby paused. "Then why does it feel like one?"
Zoe was attempting to solve a fraction problem by drawing little stars around the numbers. "If I decorate it, maybe it'll behave."
Erica snatched the paper just enough to glance. "That is not a method."
"It's a lifestyle."
Across the room, the boys' group had descended into chaos.
"Okay," said Max, tapping the desk. "We just need to isolate the variable."
Louis flicked a hand. "We need elegance, not isolation."
"We need answers," said Finn.
Ethan had his calculator out, but he was using it like a weapon of confidence rather than a tool. "I've got it."
Jake peered at his page. "You've got the wrong page."
Ethan froze. "What?"
Sam slapped a hand over his mouth to hide a laugh. Heist, meanwhile, was carefully lining up his pencils. "Maybe if we organize the stationery, the equations will feel less aggressive."
"Nothing about this is less aggressive," said Max.
Louis leaned over the worksheet. "This one is easy. It's just asking for the value of x."
"Then answer it," said Finn.
Louis smiled. "I would, but I'm preserving suspense."
"Suspense is not a math strategy," Jake said.
Mr. Hocus moved between desks, silent as a shadow with chalk dust on its collar. He stopped at the boys' table first.
"Mr. Fabulous."
Louis sat up straighter. "Yes, sir?"
"Why is your answer written in cursive?"
"Because it deserves beauty."
"It deserves accuracy."
Louis's smile faltered. "Of course."
Mr. Hocus pointed to the line. "You added instead of subtracting."
Louis blinked. "A minor artistic disagreement."
"No. A major numerical error."
He moved on.
At the girls' side, he paused over Erica's page. "Show me your working."
Erica pushed the paper forward. "I did."
Mr. Hocus scanned it. "You skipped a step."
"I knew the step."
"You assumed the step."
"I respected the step."
"You failed the step."
Lavi coughed to hide a laugh.
Mr. Hocus looked at her. "And you have made the same mistake on the next problem."
Lavi's mouth opened. Closed. Opened again. "Sir, respectfully, that's rude."
"It is educational."
Ruby's screen flashed a worried face. "He is in one of his 'truthful' moods."
Mr. Hocus heard that too. "I am always truthful."
Zoe raised her hand. "Then truthfully, sir, why does math hate us?"
Mr. Hocus considered that with surprising seriousness. "It does not hate you. It resists laziness."
Zoe pointed at the worksheet. "This one is resisting me personally."
"Then resist back," he said.
Chloe looked up. "Sir, could you explain number six again?"
Mr. Hocus's expression softened by half a degree. "Of course."
He took the chalk and, in a few quick strokes, broke the problem into smaller parts.
Ava blinked. "Oh. That makes it less terrifying."
"Good," said Mr. Hocus. "Math is rarely terrifying when approached properly."
Mia raised a hand. "Sir, what if we approach it improperly by accident?"
"Then," said Mr. Hocus, "you check your answer and correct the accident."
Ruby made a tiny mechanical hum. "That is the most responsible sentence I have heard all week."
The hour passed in a blur of erasers, muttered equations, and the occasional cry of betrayal.
Then disaster arrived wearing a perfectly ordinary face.
It began with Sam.
He stared at his paper and whispered, "No."
Finn looked over. "What?"
Sam pointed at the last problem. "I got a different answer from everybody."
Jake leaned in. "Maybe everybody else is wrong."
"Maybe you're wrong," said Max.
"Maybe all of you are wrong," said Heist in a small voice.
Louis, who had been trying to recover from his earlier errors, suddenly sat up. "Wait."
Ethan frowned. "What?"
Louis scanned the final line of his work. "I think I copied the wrong sign."
A silence spread.
Then Zoe gasped. "I did that too."
Erica looked down. "No, wait—"
Lavi turned pale. "Oh no."
Ruby's screen flickered. "I have also copied the wrong sign."
Tara stared at her page. "That would explain why my answer is negative and emotionally upsetting."
Chloe looked between them. "Did anyone get the same answer as Mr. Hocus's example?"
Nobody answered.
The room began to buzz with panic.
Ava whispered, "We all got different answers."
Mia's voice trembled. "That can't be right."
Lily had gone very still. "It means we made a mistake somewhere."
"Somewhere?" Zoe repeated. "That is not comforting."
Mr. Hocus heard the rising noise and turned from the board.
"What is the matter?"
Erica stood halfway from her chair. "Sir… I think the worksheet may be wrong."
The entire class turned to stare at her.
Mr. Hocus's face became unreadable. "Explain."
She swallowed. "The final answer doesn't match the method you taught."
Lavi added quickly, "We checked it twice."
"Three times," said Ruby.
"Four times," muttered Heist.
Mr. Hocus took the worksheet from Erica and read the problem. Then he read it again.
Then he walked to the board.
The class watched him write the equation.
He paused.
The chalk hovered.
Zoe whispered, "Oh no."
Mr. Hocus adjusted his glasses, then slowly erased one symbol and replaced it.
The room held its breath.
He finished the calculation.
The answer on the board was different from the one printed on the worksheet.
Sam's eyes widened. "Sir?"
Mr. Hocus stared at the board, then at the paper.
Then, in the most terrifyingly calm voice imaginable, he said, "The worksheet contains an error."
A collective explosion followed.
Louis threw both hands in the air. "Aha! We were sabotaged by the paper!"
Finn rubbed his forehead. "That is not a sentence I expected today."
Jake laughed once, sharply. "So we were right all along?"
"Not all along," said Mr. Hocus. "Some of you were wrong in the correct direction."
Zoe pointed dramatically at the ceiling. "Justice."
Ruby's screen displayed fireworks.
Chloe smiled with relief. "So our answers weren't all bad."
"No," said Mr. Hocus, looking displeased but honest, "they were not."
Erica folded her arms. "Then the worksheet was the problem."
"Yes."
Lavi leaned back in her chair. "I would like to formally blame the worksheet."
"Noted," said Mr. Hocus.
Then, to everyone's astonishment, he sighed.
Not a tiny sigh.
A real one.
The kind that admitted the universe had, for once, embarrassed him.
"I made the error," he said.
The room went completely quiet.
Mr. Hocus looked at the board as if it had betrayed him personally. "I copied the wrong sign while preparing the sheet."
Zoe's mouth fell open. "You?"
"Yes."
Ruby's screen flashed: **Teacher error detected.**
"Do not enjoy this," said Mr. Hocus.
"I am not enjoying it," Ruby said. "I am documenting it."
Louis covered his smile with one hand. "Sir, this is historic."
"It is unfortunate," said Mr. Hocus.
"It's kind of amazing," said Sam.
Mr. Hocus turned to him. "Do not make this a festival."
Heist raised a timid hand. "Sir… does this mean we passed?"
Mr. Hocus looked at the class.
Then, very deliberately, he said, "It means you checked your work. That is the point."
The students blinked.
He continued, "A perfect math student is not one who never makes mistakes. It is one who notices them."
The room quieted again, but this time it was a thoughtful quiet.
Chloe nodded slowly. "So the checking matters as much as the answer."
"More," said Mr. Hocus. "Because the answer without verification is only a guess wearing confidence."
Ethan let out a breath. "That was annoyingly wise."
"Thank you."
"That was not a compliment."
"I know."
Zoe raised her hand again. "Sir, does this mean we don't have to do the worksheet again?"
Mr. Hocus looked at the paper. Then at the class.
Then he said, "You will do the corrected version."
The whole room groaned.
He lifted a finger. "But."
The groan stopped.
"If you finish it properly," he said, "I will reduce tonight's study session from three hours to two and a half."
Ruby's screen lit up with a huge smiling face. "Negotiation successful."
"That is not negotiation," said Mr. Hocus.
"It is in spirit."
"Ruby."
"It is in pixels."
Despite himself, Mr. Hocus's mouth twitched.
It was so small that half the class missed it.
The other half gasped as if they had witnessed a solar eclipse.
Louis leaned toward Finn and whispered, "I think we just saw the rare smiling Hocus."
Finn whispered back, "Don't startle it."
The corrected worksheet was handed out.
This time, the class worked differently.
No one rushed.
No one guessed too quickly.
Even Louis checked his signs twice and once more for pride.
Erica and Lavi argued over a fraction until Ruby stepped in with a projected step-by-step breakdown on her screen.
Tara organized the group's work into neat columns.
Zoe, surprisingly, stopped decorating the margins and actually followed the method.
Chloe helped Mia slow down and explain each step aloud.
Lily caught a sign error before it spread.
Ava found the exact place where her calculation had gone off.
On the boys' side, Max became the unofficial logic captain. Finn checked every result. Jake, who had been skeptical at first, admitted the method was faster than chaos. Sam stopped apologizing to the numbers and started questioning them instead. Heist, with trembling courage, corrected Louis's equation before it could become a tragedy.
Louis placed a hand over his chest. "You saved me from mathematical humiliation."
"I saved us all," Heist whispered.
"Heroic."
"Please don't say that too loudly."
When the final papers were collected, Mr. Hocus sorted them in silence.
Then he looked up.
"Much better."
The class relaxed at once.
"However," he added, "some of you still treat multiplication like a rumor."
Zoe groaned. "There it is."
"Tonight," Mr. Hocus said, "you will study for two and a half hours. Not because I enjoy your suffering, but because repetition builds confidence."
Erica raised a hand. "Sir?"
"Yes?"
She glanced around at the others, then back at him. "Could we study together in the common room?"
Lavi nodded. "Group study might help."
Ruby's screen brightened. "I can time the sessions and check answers."
Chloe smiled. "We can help each other."
Ava added, "And catch mistakes before they grow."
Mia nodded. "That sounds less terrifying.
Mr. Hocus studied them for a long moment.
Then he said, "Very well. But no whispering about answers without showing the steps."
Zoe saluted. "Yes, Commander Math."
"I am not a commander."
"You are to us."
That earned a few laughs.
Mr. Hocus adjusted his glasses and gathered the remaining papers. "Remember the key points."
The class answered in a messy chorus:
"Understand."
"Practice."
"Check, check, check."
He nodded once. "Good. Dismissed."
Chairs scraped back. Books were packed. The room filled with relieved chatter.
As the students spilled into the corridor, the evening light slanted through the tall Geneva windows and turned the hallway gold.
Louis walked beside Heist, still talking far too grandly about his "near-victory."
Ethan bumped shoulders with Finn and said, "Admit it. That was actually kind of fun."
Finn snorted. "You only say that because you survived."
Jake looked back at the classroom door. "Mr. Hocus was right, though."
Sam blinked. "About what?"
Jake shrugged. "About checking."
At the front of the group, Erica glanced at Lavi. "Next time, we're reading every sign."
Lavi groaned. "I hate that you're right."
Ruby rolled smoothly beside them, screen glowing with a cheerful face. "I have already prepared a study schedule."
Zoe pointed at her. "Of course you have."
Chloe smiled. "That's helpful."
Tara stretched her arms. "Two and a half hours. We can manage that."
Ava nodded. "Together, yes."
Mia looked less frightened than before. "Together sounds better."
Behind them, Mr. Hocus stood in the doorway, watching the class disappear down the corridor.
He glanced at the corrected worksheet in his hand, then at the chalk dust on his sleeve.
"Check," he murmured to himself.
Then, after a beat, "Check again."
And for the first time that day, he looked almost pleased.
