How to caculate the substrate binary operation. I'm not sure I'm turue. I use the 2's negivate complement plus to the positive original number

Please subtract each pair of 8-bit signed binary numbers in 2's complement. You must write exactly 8 bits in the "sum" box, and write exactly 2 bits in the "leftmost two carry-out bits" box, and write yes or no (lowercase) in the "overflow" box 1) 01010101 - 00111011 8-bit result= 10011010 leftmost two carry-out bits 10 overflow (yeso)= no 2) 00010110 - 10100101 8-bit result 01110001 01 leftmost two carry-out bits = overflow (yeso)no
