Learning Target L5 (Core): I can correctly structure a careful mathematical proof including all relevant English and mathematical statements. Please remember the academic integrity policy that you swore to uphold. Proofs can be challenging. Just try your best. If you don't get it this week, you have many more opportunities! 1. Prove that if n is an integer and n is a multiple of 2, then 4n+ 24 is a multiple of 8. 2. Show that if a = b (mod m) and b = c (mod m) where a and b are non-zero integers and m is a positive integer, then a = c (mod m). (Recommended start: write the congruences as statements of divisibility, and divisility as equalities, then go from there). You can use our text, videos, notes etc, posted to Discourse.
