Calculating bits of bits.

Binary Arithmetic!

Binary arithmetic is mathematical operations like addition, subtraction, multiplication and division on binary digits 0 and 1. It plays essential part in digital electronics. Let's get started.

Binary Addition:

Binary addition forms basis for binary subtraction, multiplication and division. There are 4 rules for binary addition. Each of this case gives a sum (bit) and a carry (bit).

A	B	Sum	Carry
0	0	0	0
0	1	1	0
1	0	1	0
1	1	0	1

Binary Subtraction:

Again, there are four rules for binary subtraction. Subtraction and Borrow will be used here.

A	B	Sub	Borrow
0	0	0	0
0	1	0	1
1	0	1	0
1	1	0	0

Binary Multiplication: 

Binary multiplication is like logical AND operation. The four rules are given below.

A	B	Mul
0	0	0
0	1	0
1	0	0
1	1	1

Binary Division:

Division as we know is repeated subtraction. It has not got 4 rules. Because the divisor can not be 0. So, here is the table for binary division. 

A	B	Div
0	1	0
1	1	1

We will see some examples for each of these operation in the next post. Stay tuned!
