If the lists involved in the operation have different lengths, an error message

putting together the two lists, rather than adding them term-by-term. For
example:
In order to produce term-by-term addition of two lists of the same length, we
need to use operator ADD. This operator can be loaded by using the function
catalog (‚N). The screen below shows an application of ADD to add
lists L1 and L2, term-by-term:
