6/7
which was the closest similar scenario I could think of. We are told (disingenuously unfortunately, but that topic's for another week) that negative numbers don't have square roots... then in University "Hey! That wasn't right! We're now going to teach you about Complex numbers...". This poll is a bit different situation then, as not everybody went to University, but it does illustrate the lasting division over the issue (1/3rd of people still believe no square roots for negative numbers).

7/7 Note:University people teach things like Complex numbers, Matrix multiplication, etc, NOT order of operations - that is taught in High School (I've never seen a HS teacher get these questions wrong). If you wanna know about a topic, then ask a person who teaches that topic! IM summary: Terms can be bracketed, so they are resolved at "B" with TDL, may include an exponent, resolved by "E", but either way fully resolved before "M", so people treating them both as IM already missed the boat!
