#x+2#

Explanation:

Although it is not exactly clear what you mean by "how to do the sum" of #x# and #2#, it is typically understood that to "sum" to values just means to add them. Symbolically, that is usually represented as

#x+2#

If you think of adding as a movement along a sliding scale, then you can visualize #x# as any number you can imagine. To "add #2#" means to slide two units "above" or greater than the whatever your starting #x# value was.

If you think of adding as a counting function, then whatever #x# value is your starting point, simply increase that value two times. Add one, and then add one again.

If you need additional clarification, please advise.
