After an absence of five years, the diabolical Calculatrivia has resurfaced. And this time, bold solvers can try to earn a first prize in any of four categories -- (A) Arts & Entertainment, (M) Math & Science, (E) Earth History & Geography, and (S) Sports & Games-or valiantly go for the grand prize by combining all four parts into the (G) General category.

To solve any one of the four categories, find the values that answer the 15 questions in that category, and then use those answers to find the value (A, M, E, or S) for the mathematical expression shown in the large box above.

To solve the General (G) category, list the answers to all 60 questions in the corresponding spaces of the entry blank, as well as the values for A, M, E, and S, each determined as explained in the previous paragraph. Then calculate G (the product of A, M, E, and S, as shown in the small box above) and write the result in the appropriate blank.

In determining the unknowns, do not strain to find unusual ways to interpret any of the questions. Some may be difficult, but in each case the answer we believe to be correct is the most literal and straightforward one. In addition, please observe the following rules:

1. Do not round off any numbers unless specifically instructed to do so.

2. Where a square root appears, evaluate it as the positive square root only. Throughout the expression, standard mathematical usage is in effect.

3. The values for G, A, M, E, and/or S that appear on your entry blank must be expressed in simplest form. If your answer were 10/5, you would write it as 2; if your answer were 10/4, you would write it as 2 1/2 or 2.5.

The idea for a five-part Calculatrivia was submitted by Michael Varn, who also wrote many of the questions.
