Q
The multiplication function takes two arguments and, therefore, in the next
line are placed two more nodes. These nodes are then filled with the symbols
at positions 2 and 3, that is, “b” and “*”, obtaining:
Q
b
In this line we have a leaf node and a bud node representing a function of two
arguments (multiplication). Therefore two more nodes are required to build
the next line. And in this case, they are filled with the elements at positions 4
and 5, namely “*” and “+”, giving:
Q
b
Now we have a line with two function buds, each expanding into two more
branches. Thus, four new nodes are required in the next line. And they are
filled with the elements “b”, “a”, “Q”, and “b”, occupying respectively posi-
tions 6, 7, 8, and 9 in the ORF, obtaining:
Q
b
