Question

What is the result of the following expression?

(1 & 2) + (3 & 4)

• A. 1
• B. 3
• C. 2
• D. 0

Answer 1

$\frac{\begin{matrix} &0 &0 &1 & (1)\\ \And& 0 &1 & 0 & (2) \end{matrix}}{\begin{matrix} \ \ \ \ & 0 &0 & 0 & (0) \end{matrix}}$               $\frac{\begin{matrix} &0 &1 &1 & (3)\\ \And& 1 &0 & 0 & (4) \end{matrix}}{\begin{matrix} \ \ \ \ & 0 &0 & 0 & (0) \end{matrix}}$

$\frac{\begin{matrix} &0 &0 &0 & (0)\\ + & 0 &0 & 0 & (0) \end{matrix}}{\begin{matrix} \ \ \ \ & 0 &0 & 0 & (0) \end{matrix}}$

( 1 & 2 )=0                      ( 3 & 4 )=0

( 1 & 2 )+( 3 & 4 )=0

Hence,Option(D)0 is the correct choice.
