In (WW, May 2011, p.99) Anil introduces a construct which I will call a Truthful Arithmetical Charade. In the simplest kind, the name for a number (say, FIVE) is converted to its sequence of letter values (6, 9, 22, 5) and then an arthimetic expression (using just the elementary operations of add, subtract, multiply, and divide) is sought that uses these numbers in order to produce a value equal to the original number.
