Wow, you all must be genuises or something.
I went to a decent primary school in Australia and spend a year ( out of phase, so put forward into the second half of Year 3 and then Year 4) in the US at age 8. The thing that threw me at this age, that was part of the natural progression in that stage, was 'subtract with carry' (I'm pretty sure that was it).
I was 'put forward' past this interesting tidbit in my US school, assessed on a test that was almost entirely centeres around it, found wanting, and placed in the lowest class in school with about 7 streams. Each test I moved up a class. All up they regarded it as a triumph of American education :-)
Neither of these schools was terrible, either, and both had 'subtract with carry' around year 3. That's a far cry from longhand division.
No-one at my kids current school is doing long division in Year 2, either, although I have creeping doubts about its rigor.
I am hoping this pace continued for all y'all, so that you were doing calculus in Year 7, and proving exotic conjectures by Erdős in your first or second year of university, etc. :-)
