1+1 = 2.

The binary value of 2 is 10 hence 1+0=1.

Hence proved.

1+1=1.

In Boolean algebra its a rule, 1+1=1.

Thanks for you explaination. And any one here please can prove 1+1=1 using boolean algebra expration? Thanks again.

OR GATE OP=(A+B)
1ST AND OP=(A+B)C
2ND AND OP=[(A+B)C]D
3RD AND OP=[(A+B)C]D)E
ANS: [(A+B)C]D)E ....{AFTER SIMPLIFICATION}

B and D are not corret because there is bar on E, and in option D it should be A+B because there is or gate for this input. So option A is correct.
