+An **inner product** is a fundamental operation in [Linear Algebra](/wiki/linear_algebra) that takes two [vectors](/wiki/vector) and produces a single [scalar](/wiki/scalar). It generalizes the idea of multiplication, allowing us to define geometric concepts like length, angle, and orthogonality within any [vector space](/wiki/vector_space).
