The answer is ZERO (0) as in the question p+p=p and this is only possible when eq. will be 0+0=0( as zero added to any no. returns the no. itself as it is the additive identity).... Take any other no. Like 1then 1+1=2 which does not matches with the equation given in the question........ So the answer is ZERO.
