We go over how to find the nullity of a 2x2 matrix with four examples. First we will find the nullity of each matrix using the matrix dimension theorem, meaning we will find the rank and then subtract this from the number of columns. Recall the rank of a matrix is the number of linearly independent rows it has. We will finish by solving an example using the definition of nullity, so we will find a basis for the null space and the dimension of the null space indicates the nullity. #linearalgebra
