Mistic@lemmy.world 11 months agoOh yeah, that’s a fun one.
Where I live, this would be considered juxtaposition, at least by uni professors and scientific community, so 2(4-2) isn’t the same as 2×(4-2).
This way, equations such as 15/2(4-2) end up with a definite solution.
Usually, however, it is obvious even without assuming juxtaposition because you can look at previous operations. Not to mention that it’s most common with variables (Eg. “2x/3y”).
So,
15/2(4-2) = 3.75
While
15/2×(4-2) = 15

Not just where you live, everywhere, in Maths textbooks. Adults forgetting the rules (and unqualified U.S. teachers not teaching what’s in the textbooks) is another matter altogether.
