If I say "It works well with both computer or platform" do I use "and" or "or" to be the conjunction? and why? and do I say a computer and a platform? or just computer and platform? thanks
Maybe I don't understand, but isn't a computer a platform?
In any case, I'd use "and" with "both," and save "or" for "either."
It works well with both IBM and Mac.
It works well with either IBM or Mac.
I'm not a teacher, but I write for a living. Please don't ask me about 2nd conditionals, but I'm a safe bet for what reads well in (American) English.
