The video begins by introducing linear algebra as a branch of mathematics concerned with vectors, vector spaces, and linear transformations. A vector space is defined as a set of well-defined objects that satisfy specific axioms []. These axioms ensure that operations on these objects behave consistently, allowing us to treat diverse mathematical entities, such as functions, matrices, and polynomials, as vectors within these spaces [-]. The core idea of closure is explained through addition of real numbers and then extended to vectors; if two vectors are in a space, their sum must also be in that same space [-]. An example illustrates adding two vectors component-wise, showing that the resultant vector remains within the defined space [-].
