What's hard about it is people are fucking stupid.

No, 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 OP.

(8-5)5+2

Far easier for most people, but then you don't get the arguments...

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

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.

You got it wrong on your first try, didn't you? Lol, it's not "mean" to write a math problem. The whole point of memorizing the order of operations is so that you can solve it no matter what order the equation is written in. 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 just fail to see how you come to the conclusion that it was written in a "mean" way. It's math, there is no "nice" way to write an equation.

it's mean in that they intentionally wrote it to trip people up so we'd have this very conversion...

But how do you know they did that? Becuase it's perfectly legit the way it's written.

Because this it's trivial to write it in a way that won't cause this confusion and yet every 3 months or so someone posts another one of these gotcha no context given equations and we as the internet have this same discussion again and again. It's bait...

Well, it's causing YOU confusion yes. But to anyone who remembers the order of operation it's not confusing at all.

Because this it’s trivial to write it in a way that won’t cause this confusion

Which is exactly how it is written, for all those who remember the rules of Maths.

The operational order is fucked

No it isn't.

the way I rewrote is

Wrong.

The only reason you’d write the equation like that is

Because it's written like that in Maths textbooks

there’s no reason to write it like that unless you’re

Obeying the rules of Maths, as found in Maths textbooks

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.

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.
