     Instructions:   Review the following program and see if you can 
                     predict the outcome by completing a "pencil 
                     trace" of the code.  

                     Program output is provided at the end of this 
                     page.

     Compiler:       The program was prepared using GWBasic, which  
                     requires the use of line numbers.

10 REM This program demonstrates variables and simple math.
20 A = (5 + 2) / 2
30 B = (5 / 2) / 2
40 C = A * B
50 PRINT "A = "; A
60 PRINT "B = "; B
70 PRINT "C = "; C
99 END
10000 REM And the answer is ...
10010 REM A =  3.5
10020 REM B =  1.25
10030 REM C =  4.375
