My father & mother worked in a grocery shop ... pre-electronic version,
and to make things faster during the checkout they summarised some of
things in their head so they only had to enter it once, for example 7
liter of milk + 1 cream. I must say they were VERY VERY good in
calculating +/-/* in their heads.
As a kid I learned to do it to some degree but nowhere close to them.
And I'm amazed how often I see people trying to calculate
change = sum handed over - cost
and then trying to figure out what bills/coins should be returned
instead of doing the simple thing of just adding to the cost.
