Cs 1800 Hw 4 Discrete Structures Assignment 4 Answers 1 A 266 Discrete structures assignment 4 answers 26 26 10 52 (30 26) (30 26) (30 26) 10 ( (30 26) (30 26) (30 26)) 36 36 macaws as this would guarantee that there is. Solution we show that (a) if m is even then m 2 ≡ 0 (mod 4) and (b) if n is odd then n 2 ≡ 1 (mod 4). for (a), if m is even, then n = 2k 1 for some integer k 1. thus, n 2 = 4k 12 , so n 2 ≡ 0 (mod 4). for (b), if n is odd, then n = 2k 2 1 for some integer k 2. [note how it’s useful to have these formal definitions of even and odd.].

Honors discrete met yesterday for the first class, and it was brutal. pretty sure it was just a preview, but we went over all the iconic problems: konigsberg, hanoi, n lines divide a plane, triangulation, etc plus the "regular" cs 1800 intro to bases and binary. E) the previous two problems suggest a rule, write this rule: rule suggested is that (a mod n) (b mod n) = (a b) mod n. the remainder of the sum of two numbers is equal to the sum of the remainders of the numbers when they are divided by n. 3. 5.
