Understanding elementary matrix algebra, and the determinant and inverse of a matrix. Understanding a linear system of equations both as a set of lines/(hyper)planes in x-space and in the space of column vectors. Understanding that f(x)=Ax is a linear function/mapping in x, (like the projection Px onto a given matrix, the rotation Rx, etc).
Understand the extension of the number system to complex numbers, and the algebra of these.
Understanding the definition of a graph having a tangent, the concept of "linearization" of a function close to a given point, and the related definition of the derivative of a function.
