Reading assignment:
Section 3.8 (matrices), Sections 1.7 and 3.5 (proof strategies, conjectures), Section 2.4 (sequences and summations), and Sections 4.1 and 4.2 (math induction) ( = Sections 2.7 of Chapter 2, and Sections 3.1, 3.2, and 3.3 of Chapter 3 of the 5th Edition)

Written assignment:

1. (3 points) Show that if A₁, A₂, ..., A_n are invertible matrices that
   (A₁A₂...A_n)^-1 = A_n^-1A_n-1^-1...A₂^-1A₁^-1
   i.e. that the inverse of the product of matrices is the product of the inverses in reverse order.
   This is a generalization of Exercise 21, page 256 ( = Exercise 21, page 205 5th Ed.).
