(osler@rowan.edu) Rowan University‚ Glassboro‚ NJ 08028 Fermat’s Little Theorem [1] states that n p −1 − 1 is divisible by p whenever p is prime and n is an integer not divisible by p. This theorem is used in many of the simpler tests for primality. The so-called multinomial theorem (described in [2]) gives the expansion of a multinomial to an integer power p > 0‚ (a1 + a2 + ⋅⋅⋅ + an ) p = p k1 k2 kn a1 a2 ⋅⋅⋅ an . k1 ‚ k2 ‚ ⋅⋅⋅‚ kn k1 + k2 +⋅⋅⋅+ kn = p ∑ (1) Here the multinomial

Linear Application and Hill Cipher. Cryptography has played an important role in information and communication security for thousand years. It was first invented due to the need to maintain the secrecy of information transmitted over public lines. The word cryptography came from the Greek words kryptos and graphein‚ which respectively mean hidden and writing (Damico). Since the ancient days‚ many forms of cryptography have been created. And in 1929‚ Lester S. Hill‚ an American mathematician and

as the specific topic I would like to go deep into. Fermat ’s Last Theorem states that if n is a positive integer greater than 2‚ then the Diophantine equation x^n+y^n=z^n has no nontrivial solutions. Diophantine equation is an equation together with the restriction that the only solutions of the equation of interest are those belonging to a specified set‚ often the set of integers or the set of rational numbers. Fermat ’s last theorem has its origins in the mathematics of ancient Greece; two

Errors in Computer Arithmetic Computer Arithmetic: 1. Integer arithmetic: Virtually all the computer offer integer arithmetic. The two properties of integer arithmetic are as follows a) Result of any arithmetic operation is an integer b) Result is always exact with two exceptions • Range of integer that can be represented is not infinite but is bounded above and below. • The result of the division operation is given as the combination of the quotient

sides of a right triangle is equal to the square of the hypotenuse. For example‚ if two sides of a right triangle have lengths 3 and 4‚ then the hypotenuse must have a length of 5. The integers 3‚ 4‚ and 5 together form a Pythagorean triple. There is an infinite number of such triples. Given two positive integers‚ m and n‚ where m > n‚ a Pythagorean triple can be generated by the following formulas: Side1 = m2- n2 Side2 = 2mn Hypotenuse = side12 + side22
