What is this "order of operation" cult now with math?

[Vtile]

I just came across a two days ago with this '8/2(2+2)=?'

Well I had to say that I'm honestly really perplexed with the whole PEDMAS or similar religeaus people touting this order of operation religion. It seems that only thing that matters is this order of operation acronym and rest of the superset rules are thrown where light do not shine.

..But the expression is staged for trolling, but the last nail to the coffin is the fact that wolfram alpha is giving the absolutely wrong answer instead of the better "invalid formatting" than HP48 (Droid48 for android) gives (as for a computer).

Edit. Ps. Subject seems to be semantic war between different branches of mathematics.
