Trivia: The system of equations given during Claire's linear algebra aptitude test is: - x+2y+3w+4z=10 - 2x-y+w-z=1 - 3x+y+4w+3z=11 - -2x+6y+4w+10z=18 (The solution cannot be found using algebraic methods. However Clare's comment, "Is this a joke?", is pertinent. It is indeed a joke. The solution is simple and ridiculous: x = y = w = z = 1.)
