Are there schools that don’t teach calculator usage? Even 10-15 years ago German schools (at least in the states I looked at) had the option to teach math with either basic calculators, scientific calculators, or computer algebra systems in grades 9-13 (I think) with most schools picking scientific calculators even back then. I would expect that to have moved into earlier grades and more advanced devices nowadays.
