What do you mean, "add 6"? How?

  • 1 of 7: Selenite numbers are far easier to remember than our own 10 digits, since they're composed of only 2 symbols -- a dot and a dash.
  • 2 of 7: It is easy to do simple arithmetic with one digit.  A single dot represents "1".  Two dots represents "2".  Adding a third dot results in "3", and four dots is a "4".
  • 3 of 7: Adding one more dot to a "4", however, results not in five dots, but in a single dash -- the representation for "5".
  • 4 of 7: Selenite arithmetic works just like ours -- except using different symbols.
  • 5 of 7: It may be easiest to understand if you convert any Selenite numbers to our own numbering system.  For example, 3 dots on top of 2 dashes (the dashes are always on the bottom) represents "13".  (Each of the two dashes is five -- so 2 of them equal 10.  The three dots are another 3, which, added to the 10, gives 13.)
  • 6 of 7: If I add 6 to that 13, I would have 19.  Translating that back to a Selenite number (so that I can insert it into one of the boxes on the panel), it would be 4 dots on top of 3 dashes (4 dots meaning "4", and 3 dashes meaning "15", with the total being 19.)
  • 7 of 7: Just as with our own arithmetic, when adding columns of figures, and the sum of one column exceeds the largest number that can be represented in that column (which, in our numbering system is 9), you use a "carry".  So changing the above example from 6 + 13 to 6 + 17, the result is now 23.  But 23 would require 3 dots and four dashes -- which is too big a number for a single Selenite digit.  Instead, 23 would be represented by a "3" in the right column, and a "1" in the next column over (which represents "twenties", in much the same way that our decimal system uses that second column to represent "tens").
