I guess slow processing speed could also point to some type of learning or memory deficit, e.g. a person has to always calculate multiplication facts because the person can't remember them. But for that same example in a kid, it should be at least as likely that the kid just hasn't memorized all the facts yet for one reason or another, but is good at remembering how numbers fit together and decent at doing calculation using that knowledge.
