"A Ninja from Takigakure receives a mission to assassinate a Konoha Ninja. During the assassination attempt, the Takigakure Ninja throws a shuriken from 400 kilometers away."
"Question: If the shuriken travels at a constant speed of 100m/s, how many minutes will it take for the shuriken to hit the target? (1 kilometers = 1,000m)"
"Hiss—"
After reading the question, Konan couldn't help but suck in a breath.
'What kind of Binja throws a kunai from that far away?'
'The Land of Waves truly had some extraordinary talents.'
'Could a shuriken thrown from 400 kilometers away even cause any damage?'
'And what was this strange symbol? What did it mean?'
Unable to understand the first question, Konan moved on to the second one.
"A Ninja on patrol at sea accidentally has an artery cut by a pirate's kunai. By the time they are sent to the hospital, they have already lost 2000ml of blood."
"It is known that an adult ninja has a total blood volume of 10,000ml. The blood is currently being lost at a rate of 100 ml/s, while the hospital is transfusing blood at a rate of 300 ml/s."
"Question: How many seconds will it take to fully replenish the injured Ninja's blood?"
'?'
Konan's brain short-circuited for a moment.
'What is this?'
'Why are they losing blood while getting a transfusion? Can't they stop the bleeding first?'
Although she still didn't understand the strange symbols, she could understand the concepts of blood loss and transfusion.
'Was the medical condition in the Land of Waves so backward that they couldn't stop bleeding?'
"Hey! Do you know how to solve this?"
Izumi, seeing Konan reading so intently, couldn't help but asked.
Konan hadn't expected Izumi to suddenly ask her a question and was momentarily at a loss for how to respond.
After hesitating for a while, she could only awkwardly shake her head.
This was a bit embarrassing. She was a ninja who had experienced two Ninja World Wars, yet she couldn't even understand a child's homework.
"I'm not very familiar with these symbols."
Since she didn't understand, Konan pointed to a few mathematical symbols in the textbook and asked about them.
"Ah, you mean these symbols? We just learned them today."
Izumi, seeing where Konan was pointing, understood her confusion and explained.
"This is 'meters,' this is 'meters per second,' this is 'milliliters,' and this is 'milliliters per second.' Do you understand now?" (T/N: For those confused, remember that Naruto World use Japanese Language not English, so the meters and the others are written in alphabet. That's why Konan said it's symbols.)
The questions weren't difficult for Izumi because the teacher had explained them that morning.
With her abilities, once she understood the principles, she could easily apply them. What really confused her was that these two questions seemed a bit unrealistic.
"I understand."
Konan nodded in understanding and continued to study the questions carefully.
This time, she could read them without any issues. She realized that the core of these questions was simple calculations.
Even in Naruto's previous life, these would have been elementary school-level math problems. For Ninjas with sharper minds, this wasn't particularly difficult to learn.
Konan did a quick mental calculation and arrived at the answers.
Although she had never formally studied mathematics, her years as a Ninja had honed her logical thinking skills.
And making explosive tags was far more complicated than this.
Konan casually picked up a pen and wrote the answers on a blank sheet of paper. Izumi glanced at them and was surprised to see they matched her own answers.
She had initially thought Konan might be illiterate. She often heard Naruto say that 90% of the Ninja World was illiterate.
But this wasn't her concern. Since they had just started learning math, the teacher had only assigned two problems for homework. Now that they were done, she took out the textbook issued by the school and began memorizing its contents.
Konan watched with interest, silently memorizing the material as well.

At the Land of Waves' Ministry of Finance Building.
Kakuzu had just finished calculating this month's profits from the shipping company and the various domestic expenditures. The corners of his mouth couldn't stop curling upward.
Gato's shipping company owned over a hundred large cargo ships. Currently, only a few were responsible for transporting supplies for the Land of Waves, while the rest were out generating wealth.
Whether it was transportation, leasing, or maritime traffic, the income from each ship was a sum that ordinary people couldn't even imagine.
Especially since many high-ranking officials or wealthy merchants from the Five Great Nations liked to hold strange banquets on the ships. They had plenty of money, and Kakuzu made sure to charge them heavily.
After deducting the current expenses for Ninja and worker salaries, construction materials, and school operations, the shipping company's net profit was still quite substantial.
The Land of Waves' national treasury was growing richer.
Looking at the numbers on the paper, Kakuzu felt a sense of fulfillment he had never experienced before.
Knock knock knock!
Just as Kakuzu was lost in his small moment of happiness, a knock sounded at the door.
"Come in."
Kakuzu's voice carried a hint of euphoria, and he didn't care at all that someone disturbed his happy moment.
A staff member walked in with an information sheet, unfazed by Kakuzu's enamored expression. He knew their Minister of Finance seemed to have a peculiar love for money, and he didn't seem to care whether the money was his or not.
"Minister, an explosive tag supplier has arrived today, wanting to sell explosive tags in the Land of Waves."
"Explosive tags?"
Kakuzu's expression turned serious, and he lowered his head to think about the current demand for explosive tags in Land of Waves.
The most direct use of explosive tags was to enhance a Ninja's combat ability, as a single explosive tag was powerful enough to kill a Ninja.
Currently, the ones who needed combat power the most were the cargo ships constantly transporting goods. There had been incidents of pirates raiding the ships, which had infuriated Kakuzu so much that he had wiped out all the major pirate groups along the nearby routes.
However, there were still some stragglers operating in small groups, making it difficult to eliminate them completely. Even when hiring Ninjas to protect the ships, the quality of the Ninjas varied, and losses still occurred.
'If each ship were equipped with enough explosive tags, perhaps these losses could be reduced.'
'Moreover, according to the leader's plans, the Land of Waves would need a large number of explosive tags in the future.'
'This deal was worth considering.'
Kakuzu made up his mind and asked, "Where is this person now?"
"In the reception room near the Security Department."
"Then let's go take a look."
Kakuzu stood up, took the information sheet handed to him, and walked out, glancing at the unfamiliar name on the paper.
But when he arrived, he was completely stunned.
"V-Vice Leader?!"
