Hello everyone, i'm alittle confused, we have an exam tomarrow and i want to make sure i'm doing this right. I'm suppose to do the following: Perform the indicated subtraction with the following unsigned binary numbers by taking the 2's compliment of the subtrahend. so for one of them: 10110 - 1111 I take the 2's compliment of 1111 which is: 1's compliment: 0000 2's compliment: 0000 + 1 = 0001 now i add 0001 to 10110 10110 +0001 = 10111 now since i'm only adding a 4 bit number to a 5 bit number my final answer will only still be in 4 bits right? so it would be 0111 as the final answer right? I used a binary calculator and it said the answer is 111, but i think it just wasn't programmed to included the 0 infront.
