For the following, a subscripted number preceding the bracketed base digit(s) will represent the occurance of the base digit(s) that number of times, e.g.
_{3}[123] = 123123123; and  indicates the concatenation of the digits, e.g., 123  45 = 12345.
We are given A as 3 x
_{666}[1] and B as 6 x
_{666}[1].
The following pattern is a representation of the value of
A x B, i.e., 3 x 6 x (
_{n}[1])
^{2}, such that n > 0 :
_{ (n  1)}[2]  1  _{(n  1)}[7]  8Therefore, the digits that appear in the product
A x B are:
sixhundred and sixtyfive
2's, one
1,
sixhundred and sixtyfive
7's, and one
8.
