Fermat's little theorem
Mathematics; Number theory
If p is prime and b p then b ( p -1) =1(mod p ). Rephrased, this says that the order of b in the group of integers modulo p divides ( p -1).
Fermat pseudoprime test
Mathematics; Number theory
The simplest (and least effective) pseudoprime test. A number N is called an Fermat pseudoprime to base b if b ( N -1) =1(mod N ). A Fermat pseudoprime is more commonly just called a ...
Irrational number
Mathematics; Number theory
A real number that cannot be expressed as a fraction. Square root of two is irrational number.
Even number
Mathematics; Number theory
A number that can be divided by 2 with a remainder of 0. Examples of even numbers include 12 and 876.
Cartesian coordinate system
Mathematics; Number theory
