It turns out that a vector is orthogonal to a set of vectors if and only if it is orthogonal to the span of those vectors, which is a subspace, so we restrict ourselves to the case of subspaces.

It validates the Rank-Nullity Theorem and explores kernel spaces as subspaces of \( \mathbb{R}^n \). Key topics include linearly independent rows, pivot columns, and methods for solving linear algebra problems.
