Here is a vector space candidate. We have as our set R^2, as our vector addition x oplus y = (x_1, x_2) oplus (y_1, y_2) = (x_1 y_2, x_2 y_2), and as our scalar multiplication a cdot x = a cdot (x_1, x_2) = (a + x_1, a + x_2).
Verify the following vector space axiom:
There exists an element 0 such that for any x in the proposed vector space, x oplus 0 = x = 0 oplus x.
EDIT: The <x1*y1, x2*y2> is what it's supposed to be. Sorry, forgot to include that multiplication symbol in there so I can see why it came off as unclear. The addition symbol is the vector addition symbol, though (the circle with the plus sign in it).
