It isn’t, it’s a convention. Not sure how many times you need to be told that 🙄
THANK YOU. this is what I’ve been trying to tell you the entire fucking time. PEMDAS is not a law, its a convention.
but just in case you decide to go back on that, and since you seem to be obsessed with the idea that all notations adhere to PEMDAS - let me blow your mind:
here is the distributive law, written in the 3 notations we’ve been talking about:
prefix: *a+bc = +*ab*ac
infix: a(b+c)= ab+ac
postfix: abc+* = ab*ac*+
(not using juxtaposition multiplication for prefix/postfix for clarity)
so where does PEDMAS get involved in prefix or postfix notations?
