I think that ordering of calculation was taught around 5th grade back in my day (11yo)
Yeah, I'd say the same for central europe. 5th and 6th grade are when they throw a lot of math expression rules at you.
Thanks for confirming. I probably sounded too condescending but I wasn't sure if it was a false memory.
I loved math as a kid though, so I ran through the curriculum as fast as I could to get to the good stuff. I think having older siblings helped - it gave me a preview of more interesting material.
My memory is shit, it was apparently 27 years ago if you're right but I have no recollection to when it was. But it's like cycling: it's simple and once learned you never forget it.
Now I'm learning how to weld. We're learning Ohm's law, which is the same as order of calculation: easy basic shit, a bit far in my memory but you never forget it. But others in my class are really struggling with it. I don't get it.
U = I R so R = U / I and I = U / R. P = U I so U = P / I and I = U / P. U=Volt, I=Ampère, R=Ω(Ohm), P=Watt
This was first year in high school if I remember correctly.
