I feel like I am getting trolled
Isn't 17 the actual right answer?

Exactly
So it's just an unfunny meme?
I think it's meant to play with your expectations. Normally someone's take being posted is to show them being confidently stupid, otherwise it isn't as interesting and doesn't go viral.However, because we're primed to view it from that lens, we feel crazy to think we're doing the math correctly and getting the "wrong answer" from what we assume is the "confident dipshit".
There's layers beyond the superficial.
I fell for it. It's crazy to think how heavily I've been trained to believe everything I see is wrong in the most embarrassing and laughable way possible. That's pretty depressing if you think about it.
As most memes are.

Some people insist there's no "correct" order for the basic arithmetic operations. And worse, some people insist the correct order is parenthesis first, then left to right.
Both of those sets of people are wrong.

Presuming PEMDAS is our order of operations and the 5 next to the parentheses indicates multiplication...
2+5(8-5) -> 2+5(3) -> 2+15=17
Other than adding a multiplication indicator next to the left parentheses for clarification (I believe it's * for programming and text chat purposes, a miniature "x" or dot for pen and paper/traditional calculators), this seems fine, yeah.
...I worry about how many people may not understand how to solve equations like these.

Pemdas, parenthesis first, for a total of 3. Then multiplication, 15, then addition. 17. What's hard about this?

I got some people really angry at me when I suggested writing some math expression with parenthesis so it would be clearer. I think someone told me that order of operations is like a natural law and not a convention, and thus everyone should know it or be able to figure it out.
I sometimes like to add unnecessary parentheses or brackets to section things off and improve legibility, but I don't do any math stuff collaboratively, so I have no idea whether others would find that disruptive or helpful.

Any PEMDAS enjoyers in chat?
I assume p is for "parentheses", because where I grew up it was BEDMAS, for brackets.

PEMDAS bitches.
It's interesting that you can somewhat tell where you are from based on this, I learned it as BODMAS

Precedences are just made up social constructs, don't let the system restrict you, you can evaluate this expression however you want. Go wild.

(* (+ 2 5) (- 8 5))
Hope some LISP can clear this up
Edit:
( + 2 ( * 5 ( - 8 5 ) ) )

Hrmm.
I read that as resulting in 21.
My education system did fail me.
I plugged that into ghci as 2+5*(8-5), and it says 17.
:(
I did (2+5)*(8-5).
Doh.
[Edit: (Double doh! Mistyped that here as 5+2. XD)]
You do parenthesis first and then multiplications and then sums, you did parenthesis, then sums, then multiplications, wich is wrong.
