Question

How do you add binary numbers?

Answer 1

Binary addition is much like your normal everyday addition (decimal addition), except that it carries on a value of 2 instead of a value of 10.

For example: in decimal addition, if you add 8 + 2 you get ten, which you write as 10; in the sum this gives a digit 0 and a carry of 1. Something similar happens in binary addition when you add 1 and 1; the result is two (as always), but since two is written as 10 in binary, we get, after summing 1 + 1 in binary, a digit 0 and a carry of 1.

Therefore in binary:
0 + 0 = 0
0 + 1 = 1
1 + 0 = 1
1 + 1 = 10 (which is 0 carry 1)

Answer 2

Set up the problem vertically, and add the digits in the ones place

Add the digits in the twos place

Add the digits in the fours place

Keep adding the digits in each place value of the number until you reach your final answer

hope this helps you.
