I don't know how we've managed to get to 2025 and there's still apparently people who haven't seen a thousand shit PEMDAS posts already
#BEDMAS squad reporting for duty
There's billions of people, literally billions of them, and the vast majority do not care about niche online culture. I see you, though.

On lemmy?
The ole lemmy-a-roo
Precedences are just made up social constructs, don't let the system restrict you, you can evaluate this expression however you want. Go wild.
37
2585?
or maybe 258(-)5 = -2585?
Wait...
258 -5 = 253! thats it!!!
Any PEMDAS enjoyers in chat?
I assume p is for "parentheses", because where I grew up it was BEDMAS, for brackets.
I was taught BEDMAS as well in school (Ontario, Canada)

Yes, indeed - it encompasses parantheses, brackets, and braces.
My education system didn't fail me, I failed it.
Pemdas, parenthesis first, for a total of 3. Then multiplication, 15, then addition. 17. What's hard about this?
you go the other direction below the equator
Legit gave me pause for like half a second. Damnit lol

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
17Haha thanks, totally forgot about the markdown
Worth a reminder that *'s get converted to italics. At first I saw the 2+58-55 and was very concerned for your education.
use backslashes pefore asterisks so that the markdown parser won't think you inted to write in italics
\*like this\*
*like this*
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.
Arguably, there is no objective truth, since the symbols and rules of mathematics are assigned arbitrarily, and are basically a social contract, just like language!
...Wait, that means there's no objective meaning of "objective", crap
Well yeah take enough shrooms and everything is suddenly exposed as the artificial construct that it is. But we don't have time to wake up and reinvent language every morning ;)
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

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