The sight made my flesh creep.

Go over several movements that the running backs and quarterback can make (i.e., option, crossback plays, quick pitches, sweeps, etc.).

(1) The set R⁺ is closed under addition and multiplication. (2) If x∈R then exactly one of the following is true: (trichotomy law) (a) x=0, (b) x∈R⁺, (c) -x∈R⁺. If further R is an integral domain we call R an ordered integral domain. […] Lemma 3.5.9. If R is an ordered ring and a∈R is a positive element, then the set na:n∈ N⊂R⁺. […] Theorem 3.5.2. An ordered ring must be infinite.

I never let my schooling interfere with my education.
