Multiplication and division are the same (whichever comes first)

You do division and multiplication at the same time going left to right

I thought you'd multiply 2 and (3) first. I've not been in a math class for

Parenthesis. Then whatever comes first, division or multiplication.

TCuz

It could be clearer. But it’s to trick the dumbos that think each letter in PEMDAS is concrete

TCuz

It's just a stupid question.

supertux

Maybe for smart people. The dumbos that get it wrong don’t get it wrong for smart reasons.

There truly is no correct answer for this problem. It is ambiguous. It's a troll question

Sure. But anybody who gets past that, and says “hey, PEMDAS taught me multiplication has to go before division”

TCuz

I agree with you there. That link I posted even hits on how PEMDAS can be taught wrong and confuse people.

1 >>>>> 6/2 but you have to do the 1+2=3 first, then 2X3, then 6/6 = 1
