Proofs are best given as short and readable essays; without the English between the formulas one never knows how to interpret those formulas.

	Caveat emptor! These notes should not be used in anyway that violates the Code of Academic Integrity. Furthermore, to use these notes effectively, you should be able to prove every bullet points stated.

	Materials covered before the midterm: [http://drorbn.net/images/1/12/Midterm1.JPG Part 1] [http://drorbn.net/images/2/23/Midterm2.JPG Part 2] [http://drorbn.net/images/6/62/Midterm3.JPG Part 3]

	[http://drorbn.net/images/1/17/DeterminantsforDummies.JPG Determinants for Determined Dummies] (this would especially helps if you are lost in the topic of determinants) (or if you like bad puns)

	Errata:
	Part 1, 1L says "the characteristic of a finite field is either prime or zero." This is incorrect. The characteristic of a finite field must be nonzero and prime. On an unrelated notes, I believe there exists infinite fields of prime characteristics. Yet, a field with characteristic 0 has to be infinite.
	Part 3, 7i, the only "and" should read "or."
	Claim 7k is actually by definition, a smarter claim would have been "If there exists a finite set S such that S spans a vector space V, then V has a finite basis."
