* If S and T are in M with S ⊆ T then T − S is in M and a ( T − S ) =

* Every rectangle R is in M. If the rectangle has length h and breadth k then a ( R ) =

* Given an R-module M, the endomorphism ring of M, denoted End < sub > R </ sub >( M ) is an R-algebra by defining ( r · φ )( x ) = r · φ ( x ).

Let ( m, n ) be a pair of amicable numbers with m < n, and write m = gM and n = gN where g is the greatest common divisor of m and n. If M and N are both coprime to g and square free then the pair ( m, n ) is said to be regular, otherwise it is called irregular or exotic.

The coyote's dental formula is I 3 / 3, C 1 / 1, Pm 4 / 4, M usually 2 / 2, occasionally 3 / 3, 3 / 2, or 2 / 3 × 2 = 40, 44, or 42 Normal spacing between the upper canine teeth is and between the lower canine teeth.
