Abstract Algebra
This is not a math problem. Because there is no philosophy to choose in the subject.
premises:∀x [(Cube(x) ∧ Large(x)) ∨ (Tet(x) ∧ Small(x))]
∀x [Tet(x) → BackOf(x, c)]
conclusion:∀x [Small(x) → BackOf(x, c)]
give an informal proof. If it is not valid, use Tarski's World to construct a counter example.

Abstract Algebra
Show that, with respect to inclusion, the set S of semiprime ideals in any ring R forms a lattice having a smallest element and a largest element.
Abstract Algebra
Let A ideal in a semiprime ring R. Show that annr(A) = annl(A).
Abstract Algebra
Let A,B be left (resp. right) ideals in a semiprime ring R. Show that AB = 0 iff BA = 0.
