> 6÷2(1+2)=1
The order of operations, I believe, needs to be clearer.
Would this be a "cleaner" example of the same equation?
6÷2(1)+2(2)=1
Or could any anon write a clearer equation than OP's example?

That's useful to remember because it is how a lot of computers will read a single-line expression, but in actual practice it is not an ironclad rule. The picture above is unclear and poorly written and it really all boils down to the use of the "division symbol". Nobody actually uses that. It might be useful to use as a symbol on a calculator button, but it should be avoided in actual equations. This should be rewritten as either (6/2)*(1+2) or as 6/(2(1+2)) depending on the actual intent. The most logical and intuitive interpretation is that the 'division symbol' implies that everything before is the numerator and everything after is the denominator of a fraction. In this case it would be the latter example I provided, and the answer is 1.

I said this in the previous thread, but absolutely nobody uses that division symbol beyond grade school. It would be 6 over 2(1+2) or 6/2 by (1+2)

Nope.
Multiplication and division are in the same category for order of operations. So they go left to right.
For clarity, since the shorthand elimination of the times-sign confuses things, this can be rewritten 6 / 2 * (1 + 2).
Which is solved in these steps:
6 / 2 * 3
3 * 3
9
The answer is 9.

The problem is that when you put the 2 immediately up against the parentheses with nothing in between it's assumed that you distribute the 2 over the parentheses. And you usually don't see equations with both parentheses and that division symbol anyways.

That's what makes this tricky and why it's a meme. The 2 immediately up against the parentheses literally just means "times". Distributive property would be overkill here anyway because both are knowns so you can just add them straight away.

Nope.
Standard practice is that implicit multiplication (what you called shorthand elimination) is performed first.
Consider the following:
x/3x =
a) 1/3
b) (x^2) / 3

I think the natural interpretation is (a) but by your rules it would be (b)

If you move the 6 to the other side, it proves the answer cannot be 9 right? Just eliminate the order of operations conflict.

Solve for x:
6 / 2(1+2) = x

1 / 2(1+2) = x / 6

1 / 6 = x / 6

x = 1

This still leaves it open to conflict:

6 / 2 (1+2) = x

1 / 2 (1+2) = x/6

1/2 * 3 = x/6

3/2 = x/6

1 / x = 1 / 9

x = 9

i suppose you could perform a small proof to demonstrate that 6 / 2(1+2) does not equal 1.

suppose that 6/2(1+2) = 1
6/2(3) = 1
6/2 = 1/3
3 = 1/3 is impossible.

It's a matter of determining what the equation in the OP translates to.
It's the bottom one you provided, by the way. For it to be the top one, there would need to be a set of parentheses around 2(1+2)... so (2(1+2))

yes, it would be 1 if it was previously this way written:

so:

Nobody would write the expression on the bottom by using the format in the original picture though. By your logic, if i wrote 1/3x it would equal x/3 because i didn't use parentheses, even though anyone who is mathematically experienced would know what i meant. I agree that it is important to use lots of parentheses when inputting into a computer, because they lack context and common sense. But for single line expressions written by and for humans to read I think the top interpretation is much more intuitive and 'correct'.
