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

is the following; multiplication and division always produces larger and smaller values respectively. This is related to the order in which children are taught the concepts of multiplication‚ Division and extending the set of numbers from integers to non integers and fractions. Misconception | Demonstration of why this is incorrect | Multiplication always makes a number larger or it stays the same stays the samesolution larger than original number (5) | Multiplication can make numbers smaller

for prime triplets * Continue till all Prime Triplets are printed Question 2: A unique digit integer is a positive integer (without leading zeros) with no duplicate digits. 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. Algorithm: * Start * To input

Lemma: If n is a positive integer‚ [pic] proof: [pic] [pic] [pic] = an − bn. Theorem: If 2n + 1 is an odd prime‚ then n is a power of 2. proof: If n is a positive integer but not a power of 2‚ then n = rs where [pic]‚ [pic]and s is odd. By the preceding lemma‚ for positive integer m‚ [pic] where [pic]means "evenly divides". Substituting a = 2r‚ b = − 1‚ and m = s and using that s is odd‚ [pic] and thus [pic] Because 1
