Chapter 1 Level 1 1. Plan the Employee and Customer tables needed in the 4Corners Pharmacy database using the information Don garnered during the discovery phase. Planning each table in this database will be a time consuming process. After you complete these two tables‚ challenge yourself to plan other tables. This requires reviewing what data is already being collected‚ what data is not being collected‚ and what outputs the stakeholders at 4Corners Pharmacy want to see. You must then brainstorm

Alexandria around 250A.D. started some kind of research on some equations involving more than one variables which would take only integer values.These equations are famously known as “DIOPHANTINE EQUATION”‚named due to Diophantus.The simplest type of Diophantine equations that we shall consider is the Linear Diophantine equations in two variables: ax+by=c‚ where a‚b‚c are integers and a‚b are not both zero. We also have many kinds of Diophantine equations where our main goal is to find out its solutions

our discussion on real numbers in this chapter. We begin with two very important properties of positive integers in Sections 1.2 and 1.3‚ namely the Euclid’s division algorithm and the Fundamental Theorem of Arithmetic. Euclid’s division algorithm‚ as the name suggests‚ has to do with divisibility of integers. Stated simply‚ it says any positive integer a can be divided by another positive integer b in such a way that it leaves a remainder r that is smaller than b. Many of you probably recognise this

r = 0. (6) Q #2: a) Prove the following: ∃ an even integer n that can be written in two ways as a sum of two prime numbers. Solution: Let n = 14. Then 14 = 11 + 3 = 7 + 7 and 3‚ 7‚ and 11 are all prime numbers. b) Suppose that r and s are integers. Prove the following: ∃ an integer k such that 22r + 18s = 2k. Solution: Let k = 11r + 9s. Then k is an integer because it is a sum of products of integers 2k = 2(11r + 9s)‚ which equals 22r + 18s Q# 3: The only

For example 7‚ 135‚ 214 are all unique digit integers whereas 33‚ 3121‚ 300 are not. Given two positive integers m and n‚ where m<n‚ write a program to determine how many unique digit integers are there in the range between m and n (both inclusive) and output them.
