There are three cases when we subtract a number from another one: 1) When value of the subtrahend (number which is being subtracted) is smaller: Step-1: Determine the 2’s complement of the negative number. Step-2: Add this to positive number. Step-3: Remove the carry, the rest bits are the final result of the binary operation. The carry is called end-around-carry. 15 (01111) 01111 (01101) is the result. -2 (00010) 11110 === ==== ===== 13 101101 Ignore the end around carry i.e. the left most bit. 2) When value of subtrahend is larger: Step-1: Determine the 2’s complement of the negative number. Step-2: Add this to the positive number. Step-3: The answer is the 2’s complement of the result with a minus sign. There is no carry. 2 (00010) 00010 2s complement of the result 10011 = -(01101) -15 (01111) 10001 === ======= -13 10011 3) When both are negative: Step-1: Determine the 2’s complement of both the negative numbers. Step-2: Add them. Step-3: There is always a carry. Ignore this carry i.e. the left most bit. Step-4: Find the 2s complement of the remaining bits. This is final the result with a minus sign. -15 (01111) 10000 -2 (00010) 11101 === ======= ====== -17 101101 Ignore the carry i.e. the left most bit. Now, find 2s complement of the remaining bits 01101 = -(10001). ============================================================ Watch : Binary subtraction using 1s complement : https://youtu.be/o2nL0SaotYs Binary addition : https://youtu.be/kSX1GhJ8ayk 1s and 2s Complement : https://youtu.be/iHxtt7Kjpdc Binary Division : https://youtu.be/QxKCtzXv9S8 Binary Multiplication : https://youtu.be/BOUNYROwjMk Binary Subtraction : https://youtu.be/PSbajFDVwMI Playlist on my channel:- Class 8 : https://cutt.ly/fmUMZNc Class 7 : https://cutt.ly/vmUMKXd Class 6 : https://cutt.ly/kmUMSV6 Class 5 :- https://cutt.ly/3mXZ1dR Please Follow - # Facebook https://www.facebook.com/CBSECyberMatePage/ # Twitter https://twitter.com/cbsecyberMate # Instagram https://www.instagram.com/cbsecybermate/
