Admire the magic of the number nine. An ancient technique called "casting out nines" lets you pick out the missing digit in a bewilderingly long series of operations. Then learn to determine two-digit cube roots and also find the age of a volunteer who has hidden the number in a complicated calculation - all with the help of the number nine.
