We continued reviewing the topic of Sec 5.1: proofs by induction.

Please study the examples in Sec 5.1 (in particular Examples 1 and 2), and write out solutions to the first homework exercises: #3 & #4 from Sec 5.1 (a screenshot from the textbook with these exercises is included below. Additional exercises will be added from Sections 5.2 and 5.3 after we cover that material.)
