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.
