Old Guy,
it is impossible since counting appleas backword equals the same as counting it frontward.If you had ten apples on the table, count it from the left to the right and you will have ten, also count it from the right to the left you stil have ten, not negative ten, the same goes for front and back. Even if it started backwords the count is stil what it is at the time, and that is 23 with this one,
