I.e., it is conceptually simpler to me to count five 30's, then 30 five's (even though I do not implement it in my head as a sequence of additions, of course; I'd probably do that particular case as "half of ten 30's"). I have no idea if that's cultural or not, though.Now, when you say "count five 30's", which one do you have in mind? 5x30, or 30x5? If you meant the former, I think that _is_ cultural. I am pretty sure that I was taught in school(s) to read 5x30 as adding 5 thirty times.I think I would say "30x5" in that case. But I'm not sure where that comes from, and I'm not even 100% sure that I would say that (after thinking about it, it's hard for me to figure out what I would have done if I _hadn't_ just thought about it).
By the way, reading "30x5" as "count five 30's" disagrees with calloc(nmemb=5, size=30), which wants to add 30-byte necessary for each member 5 times to allocate 150 bytes. Anyway, this tangent is long enough ;-)
