To take the 2's complement:Take the 1's complement, that is, change each 1 to 0, and each 0 to 1.Add 1 to the result.
00110011 is the 2's complement for this unsigned number and 10110011 if this is a signed number
Well, let's think about this together. To find the 3's complement of a number, we first find the 1's complement by flipping all the bits. So, the 1's complement of 123 would be 876. Then, we add 1 to the 1's complement to get the 2's complement, which is 877. Finally, we add 1 to the 2's complement to get the 3's complement, which is 878. Just remember, mistakes are just happy accidents in the world of math!
π/2 = 90 degrees so the complement of π/4 is π/4.
60 degrees.
Surprise: it is -10002. (If you wanted to ask 1000(2), then it is 11111000(2))
To get the 2s complement, find the 1s complement (by inverting the bits) and add 1. Assuming that number is [4-bit] binary it would be 1000. If it is preceded by 0s, as in, for example, 0000 1000, then it would be 1111 1000.
To take the 2's complement:Take the 1's complement, that is, change each 1 to 0, and each 0 to 1.Add 1 to the result.
The same number of bits are used to represent 1's complement and 2's complement. To take 2's complement, first take the 1's complement, then add 1 to the result.

1's complement numbers are those numbers which are obtain after converting 1 to 0 and 0 to 1. for e.g. 110010 1's complement of this number is:001101 2's complement is obtain by adding 1 in 1's complement of number. for e.g. 2's complement of above number:001101 + 1 --------------- 001110
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.
Because addition and subtraction in 2's complement representation do not need to care about sign.
00110011 is the 2's complement for this unsigned number and 10110011 if this is a signed number
trivial.
