Answer 1

If it's 201218+304132+23015, the answer would be 528665

Answer 2

add the 3 columns separately

20 +30 +2 = 52 degrees

15+41+30 =86 minutes

18 +32 +15 = 65 seconds

since minutes is greater than 60 subtract 60 from 86 and add 1 to the degrees

now you have 52+1 - 53 degrees

and 86-60 = 26 minutes

since seconds is also greater than 60, subtract 60 from 65 and add 1 to the minutes

26+1=27

65-60 = 05 seconds

so the sum is 53 degrees 27 minutes 05 seconds
