He was abducted by Hagrid when he turned 11 so that would place him maybe around the fifth or sixth grade.

I don't know if canonically there are math classes at Hogwarts.


The thought came to while I was watching the anime Mashle. If you are into Harry Potter and One-Punch Man I'd recommend giving it a watch.

I mean, there must be a reason why wizards are constantly perplexed by muggle technology.

[–] AbouBenAdhem 134 points 9 months ago

And why goblins have to do their accounting for them.

The series would have ended much sooner if Harry had brought an AK47 to hogwarts

Although that could also be them being perplexed by the fact that muggles did it with no magic at all.

Imagine us discovering a species that developed computers and tech just like ours, but using neither transistors nor electricity.

[–] someguy3 14 points 9 months ago (4 children)

I'm not familiar with the series, what's muggle technology?

[–] reddig33 49 points 9 months ago* (last edited 9 months ago)

Muggles is wizard slang for non-magical human beings. Like Darren on Bewitched would be a muggle. He cooks his food using an oven instead of magic. The oven is muggle tech.

[–] [email protected] 23 points 9 months ago (1 children)

Muggle is a racial slur used by magic-able people to refer to magic disabled people.

[–] EndlessApollo 20 points 9 months ago (7 children)

Not a slur, you're thinking of mudblood

Non magical people living in the real world. It's you. You're a muggle.

Hermione mentioned in the first book that wizards tend to absolutely suck at things that are typically Muggle, like logic, so it follows that they probably suck at math too.

[–] [email protected] 51 points 9 months ago (2 children)

Logically, that does follow, but we're talking about wizards here.

I mean, the very existence of magic kind of nullifies the concept of math as a means to ascertain objective fact.

What good is 2+2 when 2 eyes of newt plus 2 legs of frog leads to random quantities of dancing forks with literally no respect as to the how because magic?

Math can't quantify a world where physical laws are replaced by literal nonsense, and if math could ultimately explain the mechanics of magic and predict the outcomes of its applications, the magic wouldn't be magic anymore, it would just be another great force of the universe like gravity or electromagnetism to be mapped by the scientific community.

[–] [email protected] 22 points 9 months ago

I always wondered the opposite of the harry potter universe.

So much of math was difficult to teach or obscure because of difficulties in visualization or computation. Surely there would have been at least one wizard over hundreds of years that could figure out how to use the powers of illusion magic to visualize things? To demonstrate integrals to the unfamiliar? To render a fractal like a julia set?

Even if magic iteslf followed little internal logic, it could be used as a tool, surely? But that's the sort of fridge logic (warning tv tropes link) that maybe didn't belong in a story book like Harry Potter. I had to stop reading anyway around the time house elves were introduced, anyway. I took issue with that stuff even when I was a kid.

[–] [email protected] 19 points 9 months ago (2 children)

Exactly what more than 5th grade math do you need in such world?

I think a lot of people forget what they learn in 5th grade math. You learn negative numbers. You learn unit conversion, fraction, prime, square roots.

Would more math help absolutely. Especially with the logic wizard seems to lack. But it is not like many people use higher level math today anyway.

"Arithmancy" is their name for math classes and is mentioned several times throughout the books. It is one of Hermione's favorite subjects.

At one point, the real world evil witch that is JK Rowling suggested that Arithmancy is like dviniation, but with math, saying they use numbers to predict the future. I take this to mean that the wizarding community discovered calculus independently from the rest of the world and mistook it for a new form of magic.

[–] [email protected] 29 points 9 months ago

Divination with maths is statistics.

To be fair, I suspect the average adult in real life probably only remembers, and uses, 5th grade math.

My wife, who is a big potter fan, told me they take traditional classes as well, but they are shown off screen as they aren't interesting to the story.

[–] I_Has_A_Hat 23 points 9 months ago

Pretty sure they explicitly talk about those kind of classes in the books. They don't have scenes in them, but I remember Ron and Harry complaining about arithmetic, or mathematics, or something like that.

[–] beefcat 14 points 9 months ago* (last edited 9 months ago)

"Arithmancy" is what they call their math disciplines and it's mentioned a fair bit in the books, though understandably never really shown in the movies.

I'm sure Hogwarts also covered general education stuff but that would be boring to us so they focused on the magic stuff. That's my theory though.

[–] [email protected] 39 points 9 months ago (2 children)

They literally go through the class schedule in each book. General studies are not in it.

[–] [email protected] 18 points 9 months ago (1 children)

Can you imagine how absolutely ignorant the average Hogwarts student must be then?

[–] [email protected] 33 points 9 months ago (6 children)

Wizards are, as a whole, pretty damn stupid in that universe to be fair

Boring? This is the same universe where wizards canonically defecated in the streets and used fecal vanishing spells.

However, when Hogwarts’ plumbing became more elaborate in the eighteenth century (this was a rare instance of wizards copying Muggles, because hitherto they simply relieved themselves wherever they stood, and vanished the evidence), the entrance to the Chamber was threatened, being located on the site of a proposed bathroom.

I’m just over here chuckling at your casual statement that Hagrid abducted Harry.

[–] [email protected] 18 points 9 months ago

He broke down his door, mutilated his cousin, threatened his uncle, then lured Harry away with cake (which was eaten by said cousin).

[–] [email protected] 18 points 9 months ago (1 children)

Isn't arithmetic a class in Hogwarts and just a fancy word for maths (not a native speaker)? I think only Hermione takes it though and it's only mentioned in the books.

[–] A_A 36 points 9 months ago* (last edited 9 months ago)

arithmancy - which is pseudomaths in a sense....

So that would put him only a couple years ahead of most republicans

They have arithmancy but Harry never took it AFAIK
