If p > 2 is prime, what is 2^p-2 mod p? Give the simplest answer you can. The only arithmetic operators in your answer should be one integer addition and one integer division.

STOP. Before you answer this question, ACTUALLY READ IT. THIS is NOT (2p)-2, this is 2^(p-2). AN EXPONENT. I am so sick and tired of Chegg "experts" not READING the question.

P.S. The answer is p/2+1, though I don't know why.
