This assignment is out of 50 points, which is also the point total of questions 1-5. The subsequent starred questions (*) are more challenging and are often worth more points than a non-starred question. You may choose to do any set of questions from 1-8 whose points add up to 50. Submitting only a part of a question with several parts implies that you will still be marked on the complete question. If you submit a choice of questions with a total of MORE than 50 points, your point total will be scaled out of 50. 1. (10 pts.) Prove or disprove (using the axioms and definitions of Ch. 2 of the text) each of the following statements if a, b, c, d, x ∈ R : (i) ( − a )( − b ) = ab , (ii) − ( a/b ) = ( − a ) /b if b negationslash = 0, (iii) If 0 < a < b and 0 < c < d , then ac < bd , (iv)...
