Addition, subtraction, multiplication, division
Multiplication and division of a list by a single number is distributed across the
list, for example:
Subtraction of a single number from a list will subtract the same number from
each element in the list, for example:
Addition of a single number to a list produces a list augmented by the
number, and not an addition of the single number to each element in the list.
For example:
Subtraction, multiplication, and division of lists of numbers of the same length
produce a list of the same length with term-by-term operations. Examples:
The division L4/L3 will produce an infinity entry because one of the elements
in L3 is zero, and an error message is returned.
