How to subtract 8 bit binary numbers
WebOct 18, 2024 · There are two things in a binary arithmetic operation called separately OVERFLOW and CARRY. For addition operation, The CARRY flag is set if the addition of two numbers causes a carry out of the most significant (leftmost) bits added. example: 1111 + 0001 = 0000 (carry flag is turned on) 0111 + 0001 = 1000 (carry flag is turned off)
