How to subtract the hexadecimal number 1245 from D257 using two's complement addition method?
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).

What differencess between one's complement and two's complement?
one's complement is a bitwise complement of a binary number. (ie, 1 becomes 0 and 0 becomes 1) A one's complement isn't really used as much as a two's complement. A two's complement is used in a system where the larges bit in a binary number represents a negative number. so the bits for a 4 bit number would have the values of (from right to left): -8, 4, 2, 1 this allows you to represent any number from -8 (1000) to positive 7 (0111) To find the two's complement of a number, you take the one's complement, and then add 1. This significant because if a computer wants to subtract two numbers, it simply takes the two's complement of the second number and adds them together. More significance arises in digital circuits when constructing circuits using only nand/nor gates, as these perform slightly faster than and/or gates.
Which is the gray code for number 6 in four bit formate?
The gray code for the decimal number 6 in four-bit format is 1011. To convert from binary to gray code, the most significant bit (MSB) remains the same, and each subsequent bit is derived by XORing the current bit with the previous bit in the binary representation. The binary representation of 6 is 0110, which converts to gray code as follows: 0 (MSB), 1 (0 XOR 1), 1 (1 XOR 1), 1 (1 XOR 0), resulting in 1011.
A 1 or 0 in the binary number system is called?
A 0 or 1 in a binary number is called a bit. A binary number is made up of only ones and zeroes.
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.
How do you calculate 2s complement of any binary number?
To calculate the 2's complement of a binary number, first, invert all the bits (change 0s to 1s and 1s to 0s), which is known as finding the 1's complement. Then, add 1 to the least significant bit (LSB) of the inverted binary number. The result is the 2's complement, which represents the negative of the original binary number in signed binary representation.
Twos complement of a given 3 or more bit binary number of non-zero magnitude is the same the original number if all bits except the?
ANSWER: MSB IS 1 In the 2's complement representation, the 2's complement of a binary number is obtained by first finding the one's complement (flipping all the bits), and then adding 1 to the result. This representation is commonly used to represent signed integers in binary form. Now, if all bits except the sign bit are the same, taking the 2's complement of the binary number will result in the negative of the original number. The sign bit (the leftmost bit) is flipped, changing the sign of the entire number. For example, let's take the 4-bit binary number 1101 The 2's complement would be obtained as follows: Find the one's complement: 0010 Add 1 to the one's complement: 0011
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.
What is good about the two's complement representation?
Two's complement representation simplifies binary arithmetic, particularly for subtraction, by allowing both positive and negative numbers to be processed uniformly within the same binary system. It eliminates the need for separate negative number handling, as the most significant bit indicates the sign of the number. Additionally, it allows for an easy detection of overflow and simplifies the design of arithmetic circuits in digital systems. Overall, two's complement is efficient and widely used in computing for representing signed integers.
What is the smallest 16 bit number?
The smallest 16-bit number, when represented in signed binary (using two's complement), is -32,768. In unsigned representation, the smallest 16-bit number is 0. Therefore, the context of the representation (signed or unsigned) determines the answer.
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 binary of -37 using sign and magnitude representation?
In sign and magnitude representation, the first bit is used for the sign (0 for positive and 1 for negative). The magnitude of 37 in binary is 100101. To represent -37, we set the sign bit to 1, resulting in 1 100101. Thus, the binary representation of -37 in sign and magnitude is 1100101.
How do you write 2- as a signed integer?
To write -2 as a signed integer, you simply represent it as -2. In binary, using two's complement notation (which is commonly used for signed integers), you first convert the positive version, 2, to binary (which is 10 in binary for a 2-bit representation). Then, to represent -2, you invert the bits and add 1, resulting in its two's complement representation. For example, in an 8-bit system, -2 is represented as 11111110.
How does a 4-bit 2's complement circuit operate to perform arithmetic operations on binary numbers?
A 4-bit 2's complement circuit operates by representing negative numbers using the 2's complement method. In this system, the most significant bit (MSB) is used to indicate the sign of the number, with 0 representing positive and 1 representing negative. To perform arithmetic operations, the circuit adds or subtracts binary numbers by using binary addition and taking into account overflow conditions.
