@SmartmanApps Does 3-1¾ = 1¼ or = 2¾? Most people might say the former, but implied addition should really be treated with the same precedence as regular operators, and evaluated left-to-right. So the correct answer is actually 2¾! It's OK if you got this wrong, because the way it is written is ambiguous. Really the expression should be written 3-(1+¾). #pemdas #bodmas

The criticisms of #BEDMAS are just the surface of them problems with #math classes in elementary/high school. They don't actually teach math, they teach steps and memorization. Students are unprepared to deal with novel problems, because they're taught to memorize, not understand. And this is just the surface of the problems with school in general.

#BEDMAS sounds like a holiday where you get to spend the whole day sleeping in, and I am so on board with that right now... (b s) #PEMDAS #PunktVorStrich

@Hyphlosion
Yes, it's click-bait. Without context, or better still brackets or a solidus, the statement is ambiguous and either/both answers are equally valid/invalid.

The Problem with PEMDAS: Why Calculators Disagree https://youtu.be/4x-BcYCiKCk
I always said it is a superposition until the problem is fully defined. So both answers are correct until the definition is completed. #PEMDAS #PEJMDAS
