 The mathematics operators take three different forms:
 
 * ''Unary operators'' apply an operation to each number in the input list (e.g. negate, truncate, sign)

-** <<.inline-operator-example "1.2 2.4 3.6 4.8 +[trunc[]]">>

 * ''Binary operators'' apply an operation and operand to each number in the input list (e.g. add, multiply, remainder)

-** <<.inline-operator-example "1 2 3 4 +[multiply[8]]">>

 * ''Reducing operators'' apply an operation to all of the numbers in the input list, returning a single result (e.g. sum, product)
