## missing dollar problemA version of this problem first appeared in R. M. Abraham's Diversions
and Pastimes in 1933.^{1} See also nine
rooms paradox. Solution There is no missing dollar (of course!). Adding $27 and $2 (to get $29) is a bogus operation. They paid $27, $2 went to the dishonest waiter, and $25 went to the restaurant. You have to subtract $27 minus $2 to get $25. There never was a $29; it's a phony calculation designed to confuse the unwary. ## Reference- Abraham, R. M.
*Diversions and Pastimes*. London: Constable & Co., 1933. Reprinted , 1964.
