I assume the 14A3  is also base 11  ???

 

A =10

 

If so

 

439211  = 4(11)^3 + 3(11)^2  + 9 (11) + 2  = 578810

14A311  =  (11)^3 + 4(11)^2 + 10(11) + 3  = 192810

13A11  = 1(11)^2 + 3(11) + 10  = 16410

 

5788 - 1928 + 164  =  402410

 

To  convert back to base 11

 

4024 / 11  = 365 R 9

365 / 11   =  33 R 2

33/11  = 3 R 0

3/11 = 0 R 3

 

So

 

402410  = 302911

 

cool cool cool
