Comment on I dunno
TheKingBee@lemmy.world 3 weeks agoNo, it’s written poorly to drive engagement. People read left to right and try to do math that way too, but if you want to be mean to people who don’t remember things they learned in elementary school then never applied in real life you write it like this.
(8-5)5-2
Far easier for most people, but then you don’t get the arguments…
No, it’s written poorly
No it isn’t
drive engagement
The engagement comes from people not remembering the rules of Maths
(8-5)5
That’s an invalid syntax. it’s 5(8-5) or 5x(8-5), nothing else. Why is it invalid? Imagine (8-5)-5 - am I multiplying what’s in the brackets by -5 (which gives -15), or subtracting 5 after doing the brackets (which gives -2)? Invalid syntax
Far easier for most people
Nope, it’s wrong for everyone, due to being an invalid syntax.
Yes, thank you! Sure, it’d be great if people remembered arithmetic rules, but just write it better and it won’t matter.
just write it better
It’s written like that in Maths textbooks. i.e. there’s nothing wrong with it.
It’s written the same way literally thousands of math problems in thousands of textbooks have written the same type of math problem for the last 100 years. OP did not write it that way to be “mean.” He wrote it that way because it’s a legit way to write it.
The operational order is fucked, the way I rewrote is more readable, even if you remember the order. The only reason you’d write the equation like that is to be mean, there’s no reason to write it like that unless you’re trying to trip people up.

No it isn’t.

Wrong.

Obeying the rules of Maths, as found in Maths textbooks
You got it wrong on your first try, didn’t you? Lol, it’s not “mean” to write a math problem. Seriously man, not everything is a conspiracy. No one wrote this problem on purpose just to make you fail to understand it, that’s dumb.
This was literally written for twitter content…

I studied physics a bit and order of operations was always clear. Not sure why people are down voting this.
