A short introduction

Solution to: Names & Numbers

The easiest way to solve this problem is by writing a computer program that systematically tries all possible mappings from the digits onto the letters. This will give you only one solution which meets the condition that the digits 1 and 6 are most frequently used: 
     mars         m = 4
    venus         a = 5
   uranus         r = 9
   saturn         s = 3
 -------- +       v = 2            4593
  neptune         e = 0           20163
                  n = 1          695163
                  u = 6          358691
                  t = 8        -------- +
                  p = 7         1078610
Conclusion: neptune equals 1078610.
