You have to subtract the numbers with the most flat sides first and divide by the number of pennies in your sock drawer.
Science Memes
Welcome to c/science_memes @ Mander.xyz!
A place for majestic STEMLORD peacocking, as well as memes about the realities of working in a lab.

Rules
- Don't throw mud. Behave like an intellectual and remember the human.
- Keep it rooted (on topic).
- No spam.
- Infographics welcome, get schooled.
This is a science community. We use the Dawkins definition of meme.

Something funny about everyone being so eager to show how they can solve this
Let's not do engagement bait here 😭
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
Precedences are just made up social constructs, don't let the system restrict you, you can evaluate this expression however you want. Go wild.

Any PEMDAS enjoyers in chat?
I assume p is for "parentheses", because where I grew up it was BEDMAS, for brackets.
BODMAS or BOMDAS in Australia since we call ordinals ordinals
Brackets have pretty much always been needed to disambiguate precedence between addition and subtraction (which is really all addition) and between multiplication and division
I was taught BEDMAS as well in school (Ontario, Canada)
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
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 ;)
My education system didn't fail me, I failed it.
(* (+ 2 5) (- 8 5))
Hope some LISP can clear this up
Edit:
( + 2 ( * 5 ( - 8 5 ) ) )
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.
