Binary Addition. Example 1.
Problem: 1 + 11 = ?.
Answer: 1 + 11 = 100.
If we take the first column from the right, we get the binary addition of 1 and 1, which is:
The rightmost digit of our answer is therefore 0.
The second column from the right becomes: 0 + 1 + 1 (from the carry).
In binary addition:
Therefore, the second rightmost digit is a 0 and a 1 is carried to the next column. The next column doesn't exist (there are no numbers), therefore the 1 drops into the next slot of the answer. So our answer is: 1 0 0 !
