What is the smallest positive integer that can be expressed as the sum of nine consecutive positive integers, the sum of ten consecutive positive integers, and the sum of eleven consecutive positive integers
What is the smallest positive integer that can be expressed as the sum of nine consecutive positive integers, the sum of ten consecutive positive integers, and the sum of eleven consecutive positive integers? Explain how you arrived at this number.

Let n be an odd positive integer. Consider a list of n consecutive integers, not necessarily starting with 1. Show that the average is the middle number (that is the number in the middle of the list when they are arranged in an increasing order). What is the average when n is an even positive integer instead. We learned that for the odd numbers, we would have to show why n-1/2(2k+n)+(k+n) all over n equals k+(n+1)/2.

Challenge activity: A partition of a positive integer n is the expression of n as the sum of positive integers, where order does not matter. For example, two partitions of 7 are 7 1+1+1+4 and 7=1+1+1+2+2. A partition of n is perfect if every integer from 1 to n can be written uniquely as the sum of elements in the partition. 1+1+1+4 is perfect since 1-7 are expressed only as 1, 1+1, 1+1+1, 4, 1+4, 1+1+4 and 1+1+1+4, but 1+1+1+2+2...

Goldbach's Conjecture The goal of this program is to find all unique ways to represent a given even number as the sum of two prime numbers. A prime number is an integer greater than 11 that is evenly divisible by only itself and 11. The first few prime numbers are 22, 33, 55, 77, 1111, …. The German mathematician Christian Goldbach (1690-1764) conjectured that every even number greater than 22 can be represented by the sum of two prime numbers....

Exercise 3: Write a program that reads a positive number and checks if the number can be expressed as a sum of two prime numbers. If yes, write all possible ways of expressing the number as sum of primes. Note: n is a prime if it is divisible only by 1 and itself, hence not divisible by any integer in the range from 2 to sqrt(n), both inclusive. Write a function is Prime that take a...

6.32 Theorem. If k and n are natural numbers with (k, d(n)) =I, then there exist positive integers u and v satisfving ku=(n)u The previous theorem not only asserts that an appropriate exponent is always availahle, but it also tells us how to find it. The numbers u and are solutions lo a lincar Diophantine cquation just like those we studied in Chapter 6.33 Exercisc. Use your observations so far to find solutions to the follow ing congruences.
