Number theory

Real number

Mathematics; Number theory

Any number on the number line, including irrational numbers e.g. pi, or numbers which can be represented by an infinite series of digits.

Number theory

Mathematics; Number theory

A branch of pure mathematics for studying the properties of numbers, with a particular emphasis on integers.

Integer

Mathematics; Number theory

A 'whole' number, in that it can be denoted without a fraction or decimal place.

Rational number

Mathematics; Number theory

A number which can be represented as a/b, with a and b both being integers, and b not equal to 0.

Fermat's Last Theorem was first compiled in 1637 by Pierre de Fermat, a French mathematician, in the margin of ''Arithmetica'', a text about mathematics. It wasn't until 1995 that a successful proof ...

Partition function

Mathematics; Number theory

The partition function, p(n), counts the number of ways the integer n can be written as a sum of positive integers. For example, p(4)=5 because there are 5 way to write the number 4 as a sum of whole ...

Euler pseudoprime test

Mathematics; Number theory

A more effective pseudoprime test than the simpler Fermat test. A number N is called an Euler pseudoprime to base b if b ( N -1)/2 =( b / N ) (mod N ). (Here ( b / N ) is the Jacobi symbol.) ...
