The infixed operators - and .- as well as the prefixed operator ’-’ return the term by term difference of two lists. If the two lists do not have the same size, the smaller list is padded with zeros.
| [1,2,3]-[4,3,5] | 
or:
| [1,2,3].-[4,3,5] | 
or:
| '-'([1,2,3],[4,3,5]) | 
or:
| '-'([[1,2,3],[4,3,5]]) | 
| 
 | 
When the operator - is prefixed, it should be quoted (’-’).
