It should be limited - like Orders - to only Multiplication and Addition
Because you don't want people to know when to do Division and Subtraction? 😂
Because division is the same operation as multiplication
No it isn't, but they are both binary operators.
they have the same “weight” in the order of operations (meaning, you do them left-to-right)
And where are they going to do Division and Subtraction in the left to right if you've left them out? 🙄
O - oxponent?
To the Order of. 2² is 2 to the order of 2
so 5 literally cannot be a function if that’s the case
No, but it can be and is a coefficient of the Term 5(8-5)
Depends on the language
No it doesn't
5 isn’t a valid function name, is obviously the right answer.
5 is a coefficient of the Term 5(8-5) is the correct answer
insist mathematics has exactly one perfect unambiguous syntax,
It sure does! 😂
2*(1+3) is somehow different from 2(1+3)
Yep, one is Multiplication - 2x3 - the other is The Distributive Law - (2x1+2x3) - both easily found in Maths textbooks
Syntax error
Nope! The Distributive Law
If kids where taught how to solve them properly we wouldn’t need to dumb down equasions
They are taught how to solve them properly. It's only adults who've forgotten the rules of Maths who get them wrong
an implied multiplication
There's no such thing. It's a Term/Product.
is the normal thing you learn in (I think?) somewhere between 5th to 7th grade
Yes, you learn that it's a Term/Product in Year 7
You only add an operator if it’s something else
You never add an operator, or you end up with wrong answers.
I thought math was relatively universal
It is
The US education system may be different
They have the same rules, but they don't require Maths teachers to have a Maths qualification (in Australia you have to have a Masters), and they have been sliding in world rankings for more than a decade.
I live in Australia and don’t recall my school at all teaching me this in maths class
I'm in Australia, and I remember being taught it, and I teach it.
people exist that live in other countries and every countries education system is different
The rules are the same everywhere, only the notation varies (in Germany they use . for multiply and : for divide, and say "dot before slash", slash being - and +).
No, it indicates Distribution, a(b+c)=(ab+ac), 5(8-5)=(5x8+5x5).
