l / 0 = nonsense [ any number other than 0 / 0 = nonsense ]
0 / l = infinity [ 0 / any positive integer = infinity ]
0 / any negative integer = nonsense
0 / 0 = 0 and l and infinity
0 / l = infinity [ 0 / any positive integer = infinity ]
0 / any negative integer = nonsense
0 / 0 = 0 and l and infinity
