 * The Six Noughts
 * Write down the little addition sum $A$, which adds up to $2775$.
 * Now substitute $6$ noughts for $6$ of the figures, so that the total sum shall be $1111$.
 * It will be seen that in the case $B$ five noughts have been susbtituted, and in the case $C$ nine noughts.
 * But the puzzle is to do it with six noughts.
