-1(3, 4) = ((-1)(3), (-1)(4)) = (-3, -4). Since both coordinates are real numbers, this is also a vector in ℝ². Essentially, what we did was obtain the additive inverse of the vector (3, 4). This reinforces the fact that, according to closure of scalar multiplication, the additive inverse must also
