Problem Set I, for Thursday, January 13

Mathematics 114A

Section 1.1:

• Exercise 2, page 19. This exercise, like 3, 4, 5, and 6, is purely syntactical -- there is no reference to any possible meaning the symbols might have. (If the entire course were done this way, it would not be very interesting.)
• Exercise 3, page 19. Be sure to use the induction principle.
• Exercise 6, in the commentary on Section 1.1

Solutions will be distributed in class on Friday, January 14.
