Oh 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
