Gonna keep shouting until it sticks;
Put a goddamn function sign for the parenthesis. Don't assume everyone just knows what to do with the parenthesis alone. Fml it bugs me every time this meme gets posted.
Why?
Well, everyone was taught what to do with it in high school.
What? A number next to parenthesis always means multiplication. Are people really not taught this anymore?
No, it means distribution, a(b+c)=(ab+ac)
They're taught distribution yes. It's only adults who've forgotten the rules of Maths who get these wrong
I live in Australia and don't recall my school at all teaching me this in maths class
They taught us stuff like radius and area of a circle but not this
Edit:
Also counterpoint, people exist that live in other countries and every countries education system is different
I'm in Australia, and I remember being taught it, and I teach it.
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 +).
I thought math was relatively universal. The US education system may be different, but I'm certain we're not the only place that does it that way.
It is
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.
Why should anyone do that, an implied multiplication is the normal thing you learn in (I think?) somewhere between 5th to 7th grade. You only add an operator if it's something else. It's as basic as PEMDAS.
There's no such thing. It's a Term/Product.
Yes, you learn that it's a Term/Product in Year 7
You never add an operator, or you end up with wrong answers.
Aaah, got it. So if I see something like "5-(2+4)" I will just remove the subtraction operator and call it a day. Smartman on the internet said so. 🥴
Also casual reminder not everyone on the internet is a native english speaker. Everyone but you knew what was meant.
Nope. Never said anything of the sort.
No I didn't, but nice try at a strawman 😂
There is no such thing as "implied multiplication" in any language. They are called Terms/Products in whatever language that book is using.
Google implied multiplication.
Do you write 2x or do you write 2 • x?
That's implied multiplication, if x= (a+b) then 2x becomes 2(a+b). 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).
2a=(2xa) by definition, and 5(8-5)=(5x8-5x5).
No, that's a Term/Product.
Terms/Products
I mean, I don't like to argue about this, since I am not a native English speaker, but there is an implied multiplication there.
or Factoristion, ab+ac=a(b+c) <== a Product of a and (b+c)
And yet here you are arguing with someone who is and is a Maths teacher
Nope! It's a Term/Product. There's no such thing as "implied multiplication" - you won't find it in any Maths textbook
That time I didn't use the term implied multiplication I merely said that the multiplication is implied
And there's no such thing as either 🙄
Counterpoint:
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
