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 +).
What? A number next to parenthesis always means multiplication
No, it means distribution, a(b+c)=(ab+ac)
Are people really not taught this anymore?
They're taught distribution yes. It's only adults who've forgotten the rules of Maths who get these wrong
Google implied multiplication
There's no such thing. It's a Term/Product. Google is a prime source of Maths disinformation (yes, they have been told it's wrong, repeatedly, so it's disinformation).
Do you write 2x or do you write 2 • x?
2a=(2xa) by definition, and 5(8-5)=(5x8-5x5).
That’s implied multiplication
No, that's a Term/Product.
Implied multiplication
Terms/Products
Put a goddamn function sign for the parenthesis
Why?
Don’t assume everyone just knows what to do with the parenthesis alone
Well, everyone was taught what to do with it in high school.
Found the Canadian
Nope, it's the same in Australia and the U.K.
