Binary Addition. Example 2.Problem: 1010 + 11 = ?. Answer: 1010 + 11 = 1101.
Explanation:
For the first column (from the right) we have 0 + 1. In binary addition: and the rightmost digit of the answer is 1.
For the second column, we have 1 + 1. In binary addition: Therefore, the second digit (from the right) in the answer is 0 and we carry 1 to the next column. The next column now contains 0 + 0 + 1 (from the carry). In binary addition: so that the next digit that we can fill in for the answer is 1. The final column contains 1 + 0. In binary addition: There are no more columns so our final answer is 1 1 0 1!
