Finding inverses to 2x2 matrices is easy!
In the 2x2 case, finding a matrix inverse is easy: apply a formula. Note that the potential division by zero in the formula means not all 2x2 matrices are invertible (much like how 0 isn't invertible as a number).
Learning Objectives: Compute the inverse of a 2x2 matrix.
