What is the sum of the binary numbers 1011 and 1010?

Answer 1

To find the sum of two binary numbers, we can add them together just like decimal numbers. Starting from the rightmost bit, we add each pair of bits along with any carry from the previous addition. In this case, 1+0=1, 1+1=0 with a carry of 1, 0+1=1 with the carry, and 1+1+1=1 with a carry. Therefore, the sum of 1011 and 1010 in binary is 10101.

Answer 2

Well, honey, if we're talking about adding those two binary numbers 1011 and 1010, the sum would be 10101. Just remember, in binary math, 1+1 equals 10, so don't get your panties in a twist trying to figure it out. Just keep calm and carry on with your binary arithmetic, darling.

Answer 3

I put leading zeros, so everything will line up:

01011 (which is eleven)

01010 (which is ten)

=====

10101 (which is twenty one). The rightmost column is 1+0=1. The next column is 1+1=102. Carry the 1 and you have 1 + 0 + 0 = 1. Then 1+1=102, then carry that 1 for the most significant digit.

Answer 4

The sum of the binary numbers 1011 and 1010 is 10101 in binary.
