ab: Summary: Using the elementary tools of matrix theory, we show that the
    product of two rotations in the three-dimensional Euclidean space is a
    rotation again. For this purpose, three types of rotation matrices are
    identified which are of simple structure. One of them is the identity
    matrix, and each of the other two types can be uniquely characterized
    by exactly one vector. The resulting products are investigated by using
    the basic properties of the vector cross product.
