Well maybe it's just the stuff I do but even if you do something like 'address + offset * scale'

I still want to group that to make it obvious 'address + (offset * scale)'

The former technically works but it's less obvious. And that's a dead simple example

'address + offset << scale' is notionally the same but << has a lower precedence in c than + so you get the opposite behaviour so it's better to just bracket it out of habit.

I never find that I'm adding 3 random numbers. I'm adding 2 random numbers to make a meaningful value, then adding another number so a lot of the time I do 'foo + (bar + baz)'

Maybe if you're into pure mathematics you have a different take, but in my experience it's often the case that you end up bracketing most mathmatical operations for readability anyway
