You do it exactly like decimal subtraction, and when needed you borrow from the next higher place digit, however remember you borrow 2 everytime and not 10. Some people convert the two binary numbers into decimal, do the subtraction and then convert the result back to binary. Following is an example of binary subtraction.
1001
0110
____
0011

I started explaining the borrowing process in words but it gets confusing. Please relate it to the borrowing process in decimal.
Subtract and add the sign of the greater number.
You have to add the additive inverse. To subtract q, you add -q.
Operations, or more precisely, binary mathematical operations
-5+-3 = -8 ++ Add -- Add +- Subtract -+ Subtract
Any four-digit number will do. Add it to the number 33333, to get the original number you have to subtract from.Any four-digit number will do.

If the number has a + sign then you add it, if it has a - sign, then you subtract it.
The inverse operation for subtract 5 is add 5. This is because whatever number you start with, if you first "subtract 5" and then "add 5" or if you first "add 5" and then "subtract 5" you are back to the number you started with.
Number. You need a number.
There are a few rules to perform arithmetic operations in binary numbers. According to those rules you can add or subtract binary numbers. There are only two arithmetic operations used in binary numbers, they are addition and subtraction.

If you want to use a number line to add and subtract, it can be done with a slide rule. But it is much easier to use an electronic calculator.
