I mean, obviously ten.

But I at least understand 16.

I deeply worry about the percentage just next to the other three numbers.

Your obviously is only a convention and not everyone agree with that. Not even all peogramming languages or calculators.

If you wanted obviously, it would have to have different order or parentheses or both. Of course everything in math is convention but I mean more obvious.

2+2*4 is obvious with PEDMAS, but hardy obvious to common people

2+(2*4) is more obvious to common people

2*4+2 is even more obvious to people not good with math. I would say this is the preferred form.

(2*4)+2 doesn't really add more to it, it just emphasises it more, but unnecessarily.

Nope. Rules of Maths

Neither. Multiplication is always before Addition, hence "obviously"

Of course everything in math is convention

Nope. The vast majority of it is proven rules

2+(2*4) is more obvious to common people

Weird then how many people were able to get this right without brackets for centuries before we started using brackets in Maths (which we've only had for 300 years)

Tell that obvious to over half the population who get this wrong

Way less than half actually. No teachers or students ever get this wrong, only adults who have forgotten the rules, and poll after poll puts this down around 40-45% of adults.
