I think Chris is right about the explanation you want written down doesn't exist. It may be in a 4th grade math book but not with a sprinkler example and I.m not sure this guy could make the leap from concept of apples always equals apples, nor by using granny smiths instead of braeburns does not make one oranges. Now if the bill is $3.28 and you give the checker $5.28 after he punches in the numbers do you get $2.00 change or a blank stare?
