Binary addition
Some rules to know before we move to binary addition.
0 + 0 = 0
0 + 1 = 1
1 + 0 = 1
1 + 1 = 0 & carry 1 to next more significant bit
1 + 1 + 1 = 1 & carry 1
e.g. (10010 + 10011)2
Binary Subtraction
Binary subtraction is bit complicated. This method is not used generally. Other method called 1′s & 2′s complement method are used due to certain advantages discussed in other post.
Rules of binary subtraction
0 – 0 = 0
1 – 0 = 1
0 – 1 = 1 & borrow 1 from next significant bit
1 – 1 = 0
Multiplication
Multiplication of binary digit is done in same way as done while multiplying decimal digits. The digits are either 1 or 0 which makes it really simple. But, I have still included one example.
Rules of binary multiplication
0 x 0 = 0
1 x 0 = 0
0 x 1 = 0
1 x 1 = 1
e.g. (10001)2 x (110)2
10001
x 110
00000
+10001x
+10001xx
1100110
