Those aren’t ‘rules of maths’,

Yes they are 😂

because math would work with other orders of operations as well.

There aren’t any other orders of operations.

They are conventions

Nope, rules of Maths

Other cultures could have different conventions and it would work as well

They do have other conventions, they do not have other rules. The rules of Maths are universal.

In mathematics and computer programming, the order of operations is a collection of conventions about which arithmetic operations to perform first in order to evaluate a given mathematical expression. . These conventions are formalized with a ranking of the operations. The rank of an operation is called its precedence, and an operation with a higher precedence is performed before operations with lower precedence. Calculators generally perform operations with the same precedence from left to right,[1] but some programming languages and calculators adopt different conventions.

  en.wikipedia.org/wiki/Order_of_operations
  
  isn’t a Maths textbook
  
  In mathematics and computer programming, the order of operations is a collection of conventions
  
  and rules 🙄 Haven’t even got past the first sentence you quoted and it’s already wrong
  
  These conventions
  
  Rules
  
  but some programming languages and calculators
  
  May disobey the rules and give wrong answers, like Texas Instruments calculators
  
  With math, you can invent your own notation if you like
  
  Yep, but you cannot invent your own rules 🙄
  
  This is done often.
  
  No it isn’t.
  
  And if it makes sense, you can also change the order of operation
  
  No you can’t, or you get wrong answers, like Texas Instruments calculators
  
  The notation you learn in school is just a common one, but other notations are equally valid and can be useful
  
  But the rules are universal. You seem to be confusing notation with the rules
  
  Therefore this kind of question is not a pure math question
  
  Yes it is
  
  what kind of conventions or notations people want to use
  
  We can see for ourselves quite clearly what notation they have used. There’s no mystery or debate about it
  
  The context is what allows the math question to have a single answer
  
  The rules of Maths is what gives it a single answer - that’s what they’re for! 😂
  
  The rules of math itself are much more fundamental and they don’t care about how people decided to write formulas down.
  
  Yep, one of which is The Distributive Law, a(b+c)=(ab+ac).
