Most people know that if you take any sum of money in pounds, shillings, and pence, in which the number of pounds (less than £$12$) exceeds that of the pence, reverse it (calling the pounds pence and the pence pounds), find the difference, then reverse and add this difference, the result is always £$12$, $18$s. $11$d. But if we omit the condition, "less than £$12,$" and allow naught to represent shillings or pence—
Of course, when reversing such a sum as £$14,$ $15$s. $3$d. it may be written £$3,$ $16$s. $2$d., which is the same as £$3,$ $15$s. $14$d.
