2+2 could equal 5 if you were dealing with fourth dimension techniques. A hypercube (a square in the fourth demension) is made up of a limitless number of smaller cubes all fused together at a single point, creating an outside that is inside, depending on your viewpoint. When dealing with a hypercube, if the edge of one of the smaller cubes is 2, the edge of the hypercube will be 2^i*e, because you go out of the realm of real numbers in the fourth dimension. So....if pi*i=e, then i*e=pi*i*i, which brings you into a state of vacuum, and makes the answer everything, i.e infinity. Therefore, this could be a true solution if you were dealing with the fourth dimension.
