Counting numbers are the numbers we use to count with (one, two, three, five hundred thirty-six, etc.) Whole numbers include the counting numbers but also include the negative integers (numbers like -1, -2, -3, -536, etc.) and zero.
If zero is counted as a whole number, then the first three whole numbers are zero, one and two and the product of ANY series containing zero is ZERO. If, on the other hand, only non-zero numbers are considered, then the series is one, two and three and the product is six.
It's likely that the missing letters are ff. They are the first letters of the counting numbers one, two, three, four, five, six, seven...
