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

My education system didn't fail me, I failed it.
Any PEMDAS enjoyers in chat?
I assume p is for "parentheses", because where I grew up it was BEDMAS, for brackets.
Yes, indeed - it encompasses parantheses, brackets, and braces.
2+5(8-5)
For anyone wanting to see a different way of solving it with distribution:
2+58-55 2+40-25 42-25 17
So long as you follow the basic math rules, you can solve it in many different ways to get the same result.
With formatting fixed:
2+5*8-5*5
2+40-25
42-25
17use backslashes pefore asterisks so that the markdown parser won't think you inted to write in italics
\*like this\*
*like this*
Worth a reminder that *'s get converted to italics. At first I saw the 2+58-55 and was very concerned for your education.
Let's keep it easy. There's 2 + all the other number who results in 15 = 17.
Someone may mistake by doing 2+5 then the rest of the operation, resulting in 21. But is wrong.
Could also fuck up and get 51
(* (+ 2 5) (- 8 5))
Hope some LISP can clear this up
Edit:
( + 2 ( * 5 ( - 8 5 ) ) )

Pemdas, parenthesis first, for a total of 3. Then multiplication, 15, then addition. 17. What's hard about this?
What's hard about it is people are fucking stupid.
No, it's written poorly to drive engagement. People read left to right and try to do math that way too, but if you want to be mean to people who don't remember things they learned in elementary school then never applied in real life you write it like OP.
(8-5)5+2
Far easier for most people, but then you don't get the arguments...
you go the other direction below the equator
Legit gave me pause for like half a second. Damnit lol

I'm sorry but isn't this elementary school math?
It became a meme a few years ago, people would post problems like this and argue about whose was right, as if there were no objective truth. It hurt to watch.
ya this one is super unambiguously PEMDAS, the one that has more of an argument is the one with the division of whether a/b(c) is a / (b * c) or (a / b) * c
