Ok, then explain prefix and postfix, where these conventions don't apply. How can these be rules of math when they didn't universally apply?
The order of operations tells us how to interpret an equation without rearranging it. When you pick a different convention, you need to rearrange it to get the same answer. What you did was rearrange the equation, which you can only do if you are already following a specific convention.
All conventions can produce the correct answer, when appropriately arranged for that convention, because the conventions are not laws of mathematics, they are conventions.
They obey the laws of math. Conventions aren't laws of math, they're conventions. And a quick Google search will tell you that not everyone puts juxtaposition at a higher precedent than multiplication; it's a convention. As long as people are using the same convention, they'll agree on an answer and that answer is correct.
You can be mean all you like, that doesn't change the nature of conventions
