We created math

We discovered it. There are even multiple animals who know how to count

that there was a multiplication there since it isn’t explicit

There isn't a Multiplication there, only Addition and Brackets, and Subtraction inside Brackets. It's never Multiplication unless there is a Multiplication sign.

Remember that multiplication goes first

Remember Brackets are solved first - there is no Multiplication

so it’s: 2+5(8-5) = 2+5*3

No, so it’s: 2+5(8-5) = 2+(5x8-5x3), a(b+c)=(ab+ac).

It didn’t make sense to me to multiply the 3 & the 5 with zero consideration for the “2”

That's what the order of operations rules say to do. 2 doesn't come into it until you get down to the Addition step.

just write it better

It's written like that in Maths textbooks. i.e. there's nothing wrong with it.

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.

it’s mean in that they intentionally wrote it to

Test who remembers 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

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.

Pemdas, parenthesis first, for a total of 3

Nope, a total of 15.

Then multiplication

There isn't any Multiplication, only Addition and Brackets (and Subtraction inside Brackets).

Definitely taught in parts of the US, it’s a regional thing though

It's a how good is your Maths teacher (who isn't required to have any Maths qualifications) question. The rules are the same everywhere.

In the US: I highly doubt it

The issue in the U.S. isn't Maths textbooks (same rules as everywhere else), it's poor teaching. U.S. Maths teachers aren't required to have any Maths qualifications, and they've been sliding in world rankings for more than a decade now.
