(1234)hex=(0001 0010 0011 0100)2
(DA57)hex=(1101 1010 0101 0111)2
Taking,
(1234)hex=(0001 0010 0011 0100)2
=(1110 1101 1100 1011) -1s complement
=(1110 1101 1100 1100) -2s complement
Now ,add 2s complement of (1234)hex with (DA57)hex, we get
1110 1101 1100 1100
+ 1101 1010 0101 0111
1 1100 1000 0010 0011
There is a Carry bit
Since,carry is generated.so,no is negative
Then take 2s complement of above no.Thus ,we get
0011 0111 1101 1101=(37DD)hex
(1234)hex -(DA57)hex =37DD)hex

If you mean, for example, divide one hexadecimal number by another: In any number base, you can use basically the same method you use with decimal numbers - in the case of division, the "long division". However, you have to use the corresponding multiplication table, for example, the multiplication table for multiplying two hexadecimal digits, with a hexadecimal result.
it is subtraction not substraction
You need two equations to use the addition method.
Column method can be used for both !
To subtract binary numbers using the 2's complement method, follow these steps: Convert the number you want to subtract into its 2's complement form by inverting all the bits and adding 1. Add this 2's complement number to the other binary number you want to subtract from. Discard any overflow bit if it occurs. The result will be the subtraction of the two binary numbers in binary form. This method allows for subtraction in binary by using the concept of 2's complement to handle negative numbers.
Performing one's complement addition involves adding two binary numbers by first taking the one's complement of the subtrahend and then adding it to the minuend. This method differs from traditional binary addition because it eliminates the need for subtraction by using complement arithmetic.
First, write each number in binary form:DAB7 = 1101 1010 1011 01115634 = 0101 0110 0011 0100Now take the two's complement of 5634 in two steps:1's complement: 1010 1001 1100 1011Add 1 to make the 2's complement: 1010 1001 1100 1100Now add to find your result:1101 1010 1011 0111 + 1010 1001 1100 1100 = 1000 0100 1000 0011And write the result in hex:8483This works because the two's complement is the negative of the original number.
The shopkeeper's method, also known as the method of complements, is a technique used in mental math to subtract a number by adding the complement of that number to the next higher multiple of 10. This method is particularly useful for subtracting numbers close to multiples of 10.

You take 1245 and form the two's complement of it then add it to D257. The two's complement of a number is defined as the 1's complement + 1. In signed two's complement arithmetic, the most significant bit is the "sign" bit. 1 indicates a negative number and 0 indicates a positive number. To find the magnitude of a negative number, take it's two's complement (ignoring carry bits). To get the two's complement of 1245, take the 1's complement of 1245 and add 1. In binary 1245 is 0001001001000101. The one's complement is 1110110110111010 (in hex that's EDBA) . Adding 1 to this will give you the two's complement. That is EDBA+0001 (ignore the carry if any), is EDBB. Now you add EDBB to D257 and ignore any carry, so that will be 1C012 (throw away the carry bit), C012. C012 is a negative number (the sign bit, the most significant bit, is 1). To find its magnitude, apply the two's complement algorithm above, and you'll find it to be -16365. Note: D257 is a negative number, and you're subracting a positive number, so you're going to end up with another negative number, i.e. adding the two's complement of a number is the same thing as subtracting the number. You can check your result by doing the math in decimal to see if it adds up. D257 in decimal = -11688 (you apply the two's complement to the number to find the magnitude, and the sign is negative because the sign bit, the most signficant bit is 1). 1245 in decimal = 4677. -11688-4677 = -16365 (which in hex signed two's complement is C012).
