When I was at junior school we used to do mental arithmetic, mechanical arithmetic and problems. Mental arithmetic was sums which were fairly easy to do in our heads, just writing down the answer. Mechanical arithmetic needed to be written down with some extra working out. It included adding long numbers, long multiplication and long division. Mathematics was being taught in a completely different way by the time my children were at school. So I have mentioned two out of three of our types of sums. The third type was written out mostly in words.
