Answer:

Column 11. 366

Column  12. 441

Column 13. 4548

Column 14. 25769

Column 15. 430857

Step-by-step explanation:

Here some combinations that add up to 10 are proposed, but they are other possibilities.

Column 11

13  + 25 + 12 + 26 + 73  + 24  + 40  + 89  + 23  + 41

(13  + 25 + 12) + (26 + 24) + 73   + 40  + (89   + 41) + 23

50 + 50 +  73   + 40  + 130 + 23 = 366

Column  12.

(13  + 37)  + 92  + 35  + 64  + 30  + (97   + 33) + (18 + 22 )

50  + 92  + 35  + 64  + 30  + 130 + 40 = 441

Column 13.

317  + 226  + 232  + 515  + 396  + 435  + 707  + 992  + 311  + 417

(317  + 232  + 311) + (226 + 707 + 417 ) + (515   + 435 )   + 992  + 396

860 + 1350 + 950 + 992  + 396 = 4548

Column 14.

1127  + 2632  + 1946  + 3217  + 1184  + 1936  + 2003  + 5114  + 976  + 5634

1127  + 2632  + (1946 + 1184 )  + (3217 + 2003)  + (1936    + 5114)  + (976  + 5634)

1127  + 2632  + 3130  + 5220  + 7050  + 6610 = 25769

Column 15.

13103  + 61706  + 43285  + 39134  + 96286  + 45173  + 78135  + 26232  + 19375  + 8428

13103  + (61706 + 39134)  + (43285 + 78135)    + 96286  + 45173    + (26232 + 8428 ) + 19375  

13103  + 100840  +121420   + 96286  + 45173    + 34660 + 19375  = 430857
