Be sure to follow the rule before you head out.
Rule: You must post before you leave.
The problem is whether or not that rule is taught depends on when and where you learned it. Schools only started teaching that rule relatively recently, and even then, not universally. Which of course makes for ideal engagement bait on your hellsite of choice.
Recently? The order of operations rules have been taught for more than a century (we can see them in Lennes' letter).
Order of operations in general, yes. Implied multiplication coming before explicit multiplication/division is what's recent.
