35A811 =   3 * 11^5  + 5 * 11^4 + 10 * 11^3  + 8 * 11^2  + 1 * 11 + 1   = 570648

 

A0411  = 10* 11^4  + 0 * 11^3  + 4*11^2 + 1 * 11  + 1   = 146906

 

570648 + 146906  =  717554 base 10

 

Convert  back to base 11

 

717554  / 11  = 65232 R 2

65232 /11 = 5930 R 2

5930  /11  = 539 R 1

539 / 11 = 49 R 0

49  /11  = 4 R 5

4 /11  = 0 R 4
