I’m not sure why you’re taking a oppositional tone. To be clear I’m complaining, not trying to justify it.

Literally no one I work with likes Teams but we keep using it because that’s just what we do. Other options basically don’t exist simply by virtue of being either not Microsoft or not overwhelmingly the market leader.

This was my very first thought as well. The first section of almost every Wikipedia article is already a summary.

I stand corrected

The same priority operations can be done in any order without affecting the result, that’s why they can be same priority and don’t need an explicit order.

6 × 4 ÷ 2 × 3 ÷ 9 evaluates the same regardless of order. Can you provide a counter example?
