because there is no context given

None needed. Obey the rules of Maths and you get the correct answer.

the order of operations or what those operations are exactly would be clear through the context of these formulas

It’s clear to anyone who knows the rules of Maths.

Those aren’t ‘rules of maths’, because math would work with other orders of operations as well. They are conventions. Other cultures could have different conventions and it would work as well.

  Yes they are 😂

  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.

    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).
