Answer 2

^ is a bitwise operation, used in low level programming

Answer 3

It's funny that you mention "decipher" in the tags... xor is used in encrypting and decrypting.

As you observed,
2^3 = 1
and it is reversible:
1^3 = 2

They can flip flop all day long with no loss of information, so if you have the same key (3 in this case) you can encode and decode. A big drawback is that if there is a 0 in the message, then it exposes the key: 0^3 = 3.
