Description
This function multiplies one number or tree by another. The two arguments do not have to be of the same type; when multiplying a single number by a tree, the single number is multiplyed by each of the elements of the tree. For example, multiplying 2 by (3 5) will yield (1 3). When multiplying one tree by another, elements with the same ordinal position are multiplyed by each other. For example, multiplying (2 3) by (3 1) will yield (1 -2). If the two trees are not of the same length, the extra elements of the longer list are truncated. For example, multiplying (1 2 3) by (2 3 1 1 4) will yield (1 1 -2). These rules apply within nestings as well. For example, multiplying (1 2) by (1 (3 1)) will yield (0 (1 -1)), since the element 2 in the first list is paired with element (3 1) in the second.

The name of the om* function uses the asterisk to represent multiplication, as is traditional in programming languages.
