_sum = 10 - 7 ............ _sum is 3

Array
_result = [1,2,2,player,"String"] - [2,player,player,"String"] ............ _result is [1]

Comments:
Note that this way of removing elements from an array will not work if those elements are themselves arrays. For example [ [0,0,0],[1,1,1],[2,2,2] ] - [1,1,1] will not remove the element [1,1,1] from the first array.

A more practical example: [getPos unit1,getPos unit2,getPos unit3] - getPos unit3
will not remove the position of unit3 from the first array.
