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.
Someone mentioned this community below; I wanted to highlight it.

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.
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.
I think the one exception is their money, you definitely need some basic math to use it.
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.
