ya this one is super unambiguously PEMDAS
Spoiler alert: they all are
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
No it doesn't, The Distributive Law, a(b+c)=(ab+ac), thus a/b(c)=a/(bxc).
Arguably, there is no objective truth
Yes there is, just look in Maths textbooks
since the symbols and rules of mathematics are assigned arbitrarily
The signs are, the rules aren't.
are basically a social contract, just like language!
Nope and nope. It's a tool for calculating things, nothing like a language at all.
no objective meaning of “objective”
There is, in a dictionary, just like the rules of Maths are in Maths textbooks
I’m sorry but isn’t this elementary school math?
No, high school. The Distributive Law isn't taught until Year 7
2 + 5(8 - 5) = 2 + (5 × 8) + (5 × -5)
Nope. 2 + 5(8 - 5) = 2 + (5 × 8 - 5 ×5) . a(b+c)=(ab+ac)
Gotta distribute:
Yes, but...
2+(8+5)-(5+5)
You didn't. 2+5(8-5)=2+(5x8-5x5)
then Division or Multiplication
There's neither, only Addition and Brackets (and Subtraction inside Brackets).
8-5= 3 3*5=15
Nope. 2+5(8-5)=2+(40-25), The Distributive Law, a(b+c)=(ab+ac)
most of the ambiguous problems that get passed around
There aren't any ambiguous ones, and anyone who thinks they're ambiguous has forgotten the rules of Maths.
This one is just…math
They ALL are
it’s
a badly
written
math
problem
No it isn't.
none of the people writing these better be teachers
I am, and it's written correctly
You have to be more clear than this
It's already 100% clear to everyone who remembers the rules of Maths
assumed the math problem was one of the ambiguous ones
NONE of them are ambiguous
What du you mean, not writing it properly?
They mean they don't remember being taught that is the correct way to write it
it’s like saying 5 apples
5 baskets each with 3 apples actually
The multiplication is implied
No it's not. It's explicitly The Distributive Law, a(b+c)=(ab+ac). There is no Multiplication
