Plus 2 and minus 2

 I feel it is difficult to get an expression for 2.

However I managed to get them. One is plus 2. Which is a rather simple one. And another is -2. It is complex and involves two sum and one product operation. This one is inspired from the famous Euler expression e to the power i theta plus 1 equals zero.
