Consider the following two strings of digits: 11001010100101011 and 110100011000100. First consider them to be in base 10 and sum them to get n. Then consider them to be in binary, sum them, write the answer in binary, then interpret the digits of the sum as if they were in base 10 to get m. What is n-m?
I'm not sure if I understand your question!!. I will give it my interpretation!
11001010100101011 + 110100011000100 = 1111111 0111101111 - this is their sum in base 10 = n
11001010100101011 + 110100011000100 = 1111111 0111101111 - this is their sum in base 2 = m
Then, if we interpret m in base 10, then obviously the difference n - m =0
