SUMMARY
In vector mathematics, a negative quantity in the positive z direction is equivalent to a positive quantity in the negative z direction, as expressed by the equation -Âz = Â(-z). This confirms that vectors do not possess negative magnitudes, reinforcing the concept that directionality is key in vector representation. The discussion emphasizes the importance of understanding vector signs and their implications in physics and engineering.
