Mathematical Puzzles These puzzles (most of them old classics) from various sources can be used with pupils who finish classwork early. Most of the questions were chosen with enthusiastic‚ bright early teenagers in mind. Some of the puzzles are also appropriate for class work - an initial worked example on the board will help a lot. There are a few trick questions. Some questions can be quickly answered if you chance upon the right approach‚ but the ’long’ solution isn’t too arduous. Several of the

------------------------------------------------- Prime number A prime number (or a prime) is a natural number greater than 1 that has no positive divisors other than 1 and itself. A natural number greater than 1 that is not a prime number is called a composite number. For example 5 is prime‚ as only 1 and 5 divide it‚ whereas 6 is composite‚ since it has the divisors 2 and 3 in addition to 1 and 6. The fundamental theorem of arithmetic establishes the central role of primes in number theory: any integer greater than 1 can be expressed

Suppose a | b ‚ so that b = at for some t ‚ and b | c‚ so that c = bs for some s. Then substituting the first equation into the second‚ we obtain c = (at)s = a(ts). This means that a | c‚ as desired. 6. Under the hypotheses‚ we have c = as and d = bt for some s and t . Multiplying

She takes her “cue from the Professor” (113) and makes a habit of carrying a pencil and notebook around so that she can quickly do calculations to figure out if any number she sees is prime. While cleaning at another family’s home‚ she can’t help but to explore the numbers in every place‚ including the serial number engraved on a refrigerator. Much like the way the Professor pulled

there were two brothers. Composite and Prime Number. They were fraternal twins; Composite Number’s factored form was 2•2•2•3 and Prime Number’s was 23•1. Nobody liked Prime Number because he couldn’t be factored and nobody wanted him to play with them in their games; like prime factorization (because he couldn’t be factored at all). Prime Number’s only friend was Prime Polynomial. They both had one major thing in common; being prime. While Composite Number has all his composite friends who play factoring
