I have a question that I cannot find anywhere on the internet apparently. How can I subtract a 6 bit binary number by a 7 bit binary number using the borrow method. This was the question on a test and I couldnt answer it but I understand how to use the borrow method.
My professor does not want us to flip the numbers like you would normally do. He wants us to answer it as is to show we understand the borrow method. But to me this makes no sense.
111100-
1111111

when I get to the end, I cant borrow another 1 and none of the multiple choice answers made any sense to me
My guess was 1111101 but thats wrong
