MATHEMATICS

"The side of any triangle is determined with the formula of A squared plus B squared minus 2AB cosine C…"

"The quadratic formula can be used to find the x intercepts of any quadratic function…"

"You can solve for local minimum and maximum values by finding when the derivative of the function is zero…"

A hundred Ectoplasm clones gave math notes at a hundred separate chalkboards on a hundred separate topics. The students of 1-A took notes in varying states of panic. Kaminari drooled on his chin as sparks crackled out of his frazzled hair, Iida's engines fired up as his arms moved quickly enough to ignite his paper with each stroke of his pen, and Shoji made a writhing sea of arms to scribble notes on his back.

Yaoyorozu used her Quirk to make whole stacks of paper with notes from each chalkboard. Sadly, said papers had their contents scrambled together, leaving the trigonometric functions with a basic derivative proof unceremoniously grafted to their left kidney.

Izuku sat at the eye of the storm, motionless save for his eyes flickering between all the clipboards. Bakugo paused his frantic note-taking every so often to scowl and mutter about being up to something.

Simultaneously, all the Ectoplasm clones said, "And that's every maths lecture for the next three years. Now, here's the pop quizzes. You aren't allowed to use your notes. I hope you were paying attention!"

"WHAT!"

Each clone had its own stack of quizzes. By the time they passed them out, each student had a mountain of math problems.

"You have one hour to finish them all."

"How is that fair?" Mineta shouted.

"What?" the clones asked. "These only took me five minutes. You have plenty of time."

Izuku's desk was the only one without a quiz. Ectoplasm himself brought out a different stack, one far taller than the rest. While the other students openly wept as they tore through their quizzes, Izuku raised his hand.

"Excuse me, but these do not appear to be quizzes."

Ectoplasm gave Izuku a deadpan stare. "Yesterday, you found the last digit of pi, solved world hunger to the nearest millionth decimal point, determined that the answer to life, the universe, and everything was 42, and calculated the average airspeed velocity of an unladen sparrow, both African and European. There's only one way I can challenge you further: tax exemptions."

Izuku nodded and mumbled calculations under his breath. Within moments, the air around him grew uncomfortably warm. Smoke wafted from his ears, and sparks flew from his hair. His head twitched erratically. His voice rose in pitch and volume, growing faster and faster as Izuku's brain frantically tried to process Ectoplasm's taxes.

Izuku wrote a number, and his head slammed into his desk. Ectoplasm worked the tax forms out from under him and cheered. "Hah! I get an extra five-hundred yen back! Take that bureaucracy!"

In the margins of his quiz, Katsuki scribbled, "Robots weak against taxes."

Why teach a lecture a day for a hundred days when you can teach a hundred lectures per day for a single day?
