Arithmetic operators
   +     Addition
         int sum = 4 + 7;
   -     Subtraction
         float difference = 18.55 - 14.21;
   *     Multiplication
         float product = 5 * 3.5;
   /     Division
         int quotient = 14 / 3;
   %     Modulo Reduction (Remainder from integer
division)
         int remainder = 10 % 6;
NOTE: For integer arguments / and % correspond to
the Pascal div and mod operators. Do not use ^ for
computing powers – it denotes “bitwise XOR”.
