... What does it mean - "to reduce a fraction" ? To reduce a fraction means to divide both the numerator and denominator of the fraction by the same number. When we reduce a fraction, does the reduced fraction represent a bigger or a smaller part than the original fraction? ...

practice questions
... (a) If x is even, then x2 is even. (b) x is even implies x2 is even. (c) x is even only if x2 is even. (d) It is necessary that x2 be even for x to be even. Note that “x2 is even is necessary for x is even” is not even a correct English sentence! Part of the point of this question was to make people ...

Factoring a Monomial from a Polynomial
... To factor we need to make use the Greatest Common Factor (GCF). If you are having trouble seeing the GCF you can start with a common factor and continuing pulling out the common factors until no common factors remain. Remember that the GCF of two or more numbers is the greatest number that divides i ...

FERMAT`S LITTLE THEOREM 1. Introduction When we compute the
... m is prime. But 3m−1 ≡ 76861 6≡ 1 mod m, so a = 3 would violate Fermat’s little theorem if m were prime, so it can’t be prime. The number 80581 must be composite. These examples illustrate a point that is at first hard to believe: proving a number is composite and factoring a number in a nontrivial ...
