To find the 2s complement, invert all the bits (to get the 1s complement) and add 1:
10001100 00111001 → 01110011 11000110 + 1 = 01110011 11000111
If you have an operator missing between the two numbers then if it is subtract:
10001100 - 00111001 = 10001100 + 11000111 = carry set & 01010011 & overflow set.
If not subtract but some other operator, please re-ask your question with the operator written out as a word.

What is the range of numbers that can be encoded in 4 bits using 2s complement notation?
Using 4 bits the signed range of numbers is -8 to 7. When working with signed numbers one bit is the sign bit, thus with 4 bits this leaves 3 bits for the value. With 3 bits there are 8 possible values, which when using 2s complement have ranges: for non-negative numbers these are 0 to 7; for negative numbers these are -1 to -8. Thus the range for signed 4 bit numbers is -8 to 7.
What is the answer to 2s plus 16 equals 4s - 6?
2s + 16 = 4s - 6 Subtract 2s from both sides: 16 = 2s - 6 Add 6 to both sides: 22 = 2s divide both sides by 2: s = 11
What is the integer equivalent represented by 2's complement of the binary number 10001011?
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.)

What is the binary complement 8 bit representation for negative 19?
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

How do you detect overflow when adding two numbers in 2s complement form?
You can detect overflow if the result turns out to be negative (which is the same as checking to see if the sign bit is 1). For example if you tried to add 5 and 6 in to 4-bit 2s complement, you would get 0101 + 0110 = 1011, which is a negative number since the sign bit (the 1 on the left) is a 1. This is an overflow.
What is 2s complement?
Two's complement is a mathematical representation used to encode negative numbers in binary systems. In this format, the most significant bit (MSB) indicates the sign of the number, where '0' represents positive and '1' represents negative values. To find the two's complement of a binary number, you invert all bits (turning 0s into 1s and vice versa) and then add 1 to the least significant bit. This method simplifies binary arithmetic, allowing for straightforward addition and subtraction of signed numbers.

The 2's compliment of the number 1000 is?
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.
Why we use 2s complement?
Two's complement is used for representing signed integers in binary because it simplifies arithmetic operations, especially addition and subtraction. It allows for a unified treatment of positive and negative numbers, eliminating the need for separate circuits for each operation. Additionally, it simplifies the process of determining the negative counterpart of a number and avoids issues like sign bit ambiguity. This representation also maximizes the range of values that can be represented for a given number of bits.
What is 2s complement of (-13)10?
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.
What is the Largest 8 bit negative number which can be represented using 2s complement?
The largest 8-bit negative number that can be represented using two's complement is -1. In two's complement representation, -1 is expressed as 11111111 in binary. This is because the most significant bit (MSB) indicates the sign, and in this case, it is set to 1, indicating a negative number. The range of 8-bit two's complement numbers is from -128 to 127.
