If the lists involved in the operation have different lengths, an error message
(Invalid Dimensions) is produced. Try, for example, L1-L4.
The plus sign (+), when applied to lists, acts a concatenation operator,

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:
