I never let my schooling interfere with my education.

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.

The sight made my flesh creep.
