### A good answer might be:

(-2, 5, -6)^{T} **·** ( 1, 2, 3)^{T} =
(-2)*1 + 5*2 + (-6)*3 = -2 + 10 -18 = -10

# Any Real is Possible

The answer is a negative real.
This is fine.
Dot products produce all kinds of reals: negative, zero, positive.
However, something interesting happens
when you take the dot product of a vector with itself.
