Here is a set of review problems for Midterm 1, and here are some solutions. You do not need to hand this in. A few corrections: Problem 10e should only ask you to compare the statements a-c (do not compare with (d)). In Problem 10f, when they say the 'original statement', they mean the statement 'for all real numbers a, b, c, P(a, b, c)'. Problem 16b: You should assume throughout that x is not zero. Problem 16c: You should assume throughout that x is not -1.
