There are to this day people in coding that don't know about operator precedence. I've seen bugs because of that not only once… Just having a very simple rule and making everything else explicit is not bad for a computer language. You know, explicit is better than implicit. At least some serpents said that. Also: https://www.pyret.org/docs/latest/op-precedence.html#%28part._.But_why_not_use_precedence_%29 https://www.pyret.org/docs/latest/op-precedence.html#%28part...

A better way to implement this is to always enforce parentheses around binary operators - which avoids misleading someone who is used to mathematical precedence (whether it is from maths or from using other languages).

  Not everybody likes LISP's syntax though. ;-) I actually think what Pyret does is reasonable.

Honestly confused why the concept of some arbitrary "order of operations" was ever entertained at all. You'd think ye olde algebraists would have recognized the ambiguity as a glaring problem right away. After a bit of light searching I'm still struggling to find any historical reasoning behind it.
