Neat little mathematical trick. Think that any two digit number between 10
and 99 can be expressed as 10X + Y. where X is a digit ranging from 1 to 9
and Y is a digit ranging from 0 to 9. Therefore, the number 37 would be 10
times 3 plus 7. This means in this case the X is equal to 3 and the Y is
equal to 7. The sum of the digits is 3 + 7 = 10.and the final number to
lookup in the table is 37-10 = 27. Well, the symbol for 27 is C+ (think of
my + sign as the star in the chart). Doing the math using algebra the
equation for the final number would be 10X +Y -(X + Y) . this would be equal
to 10X + Y - X - Y when I remove the parentheses. and by adding up the X's
and Y's, this becomes equal to 9X since the + Y and - Y cancel out.
Therefore, the answer always becomes equal to 9 times an integer between 1
and 9. Notice that every 9X number in the chart has the same C+ symbol.
Therefore, no matter what two digit number you pick you will always be
directed to the same symbol in the chart.
Could be a good way to call tunes in a band that only knows one tune.
