Math Problem Statement

What is the 8-bit two's complement for the following integer? −53

Solution

To find the 8-bit two's complement for 53-53, follow these steps:

Step 1: Find the binary representation of 5353 (positive integer)

First, convert 5353 into binary:

26 \div 2 = 13 \, \text{R}0 \\ 13 \div 2 = 6 \, \text{R}1 \\ 6 \div 2 = 3 \, \text{R}0 \\ 3 \div 2 = 1 \, \text{R}1 \\ 1 \div 2 = 0 \, \text{R}1$$ So, $$53$$ in binary is $$110101$$. To represent it in 8 bits, pad with zeros: $$53 = 00110101_2$$ ### Step 2: Find the one's complement To find the one's complement, invert all the bits (change $$0$$s to $$1$$s and $$1$$s to $$0$$s): $$\text{One's complement of } 00110101_2 = 11001010_2$$ ### Step 3: Add 1 to get the two's complement Now, add $$1$$ to the one's complement: $$11001010_2 + 1_2 = 11001011_2$$ ### Conclusion: The 8-bit two's complement representation of $$-53$$ is: $$11001011_2$$ Would you like more details or have any questions?
