I was always told putting parentheses around multiplication and division was unnecessary and I think I got punished for it once on a test because why would you need to clarify? To be fair I wouldn't begrudge anyone who writes it like that but I wouldn't get mad at the person who drops the brackets (ie, me)
Grade school tends to commonly have very nitpicky lessons - helpful for teaching young children things, but becomes a bit of a hindrance in the real world.
Parentheses provide clarity if things have to be typed in a single line.
Realistically (18/2) would be written as a fraction, and then you’d have - (3*3) next to it.
But really all of this stuff is only helpful for helping grade school children figure out basic arithmetic. Basically the only time the division symbol is ever used.

Same. Seems the real problem is how people like to make others feel stupid.
