8-bit 2s complement representation of -19 is 11101101 For 1s complement invert all the bits. For 2s complement add 1 to the 1s complement: With 8-bits: 19 � 0001 0011 1s � 1110 1100 2s � 1110 1100 + 1 = 1110 1101

To find the 2's complement of (-13) in binary, first, convert the positive value (13) to binary, which is 1101 in 4 bits. Then, invert the bits to get 0010, and finally, add 1 to this result, resulting in 0011. Thus, the 2’s complement representation of (-13) in 4-bit binary is 0011.
-15 is 11111111 and 2s com is 1111 0001
To find the two's complement of -37 using 8 bits, first represent +37 in binary, which is 00100101. Next, invert the bits to get 11011010, and finally, add 1 to this result: 11011010 + 1 = 11011011. Therefore, the two's complement form of -37 in 8 bits is 11011011.
To get the 2s complement, change all 1 bits to 0s and all 0 bits to 1s, and add 1 to the result. So the 2s complement of the 8-bit binary number 10001011 is the binary integer 01110101. If you want that in decimal, then remember that each place value column is twice the value of the place value column to its right, and the rightmost place value column for an integer is 1. Thus 01110101 in decimal is 64 + 32 + 16 + 4 + 1 = 117 (And 10001011 as a signed 8-bit binary integer represents the decimal integer -117.)
