The equality given in the nth formula of section m.

The inequality given in the nth formula of section m.

The nth exercise given at the close of section m.

The nth figure accompanying section m.

The nth theorem in section m.

A corollary to Th. (/w, n)

A lemma used in proving Th. (w, n). If several corollaries or

lemmas go with Th. (/w, /i), they are distinguished by use of a

letter written following the number n. Thus, Cor. (2,3b)

signifies the second corollary to Th. (2, 3).
