Align the two numbers as you would in decimal subtraction.
Append leading zeros if necessary to represent both numbers with the same number of digits
Apply two's complement to the second term
Add the complemented number to the first term.
The sum in the previous step should have one more digit than you started with.

How do you subtract 2 binary numbers?
An easy way is to convert them to decimal, subtract, then convert the answer back to binary.
What is 1110-111 in binary?
1110-111 in binary = 999
How do you subtract a combination of binary octal and a hexadicemal?
You must first convert them to a common base. For example, convert all to binary.
How do you convert the number 65 to binary?
The number 65 in binary is 1000001. The digits in a binary number are exponents of 2 rather than 10, so that for a seven digit number in binary, the digit places represent 64, 32, 16, 8, 4, 2, 1 instead of increasing values of 10. 1000001 = 64+0+0+0+0+0+1 = 65 To create a binary number, use places for all exponent values of 2 that are less than your number. Subtract the largest digit (here 64) and see if each successive smaller digit can be subtracted. If it can, enter a 1 value and subtract again. Here, the remainder is 1, so write 0 values in the digit places for 32, 16, 8, 4, and 2, and then the final 1 = 1.
What is the distributive property of subtraction?
The distributive property of subtraction states that when subtracting a number from the sum of two other numbers, you can subtract the same number from each of the two numbers separately, and then subtract the two results. This can be represented as: a - (b + c) = (a - b) + (a - c).
