Extracted text: Topic: Binary Subtraction Subtopic: Two's Complement 1. Fill-in the blanks a.) To represent +3 in two's complement, you only need three bits: 011. But let's say you have an 8-bit register, and hence store all integers as 8-bit. How would the 8-bit register store +3? In other words, how do you represent +3 in 8-bit two's complement? Answer: b.) -3 can be represented in two's complement with 3 bits: 101. (Check if this is correct!) Using the same concept as the item above, you should be able to prove to yourself that in 8 bits, -3 is
