The Legendre symbol is used ... by mathematicians in attempts to woo women. (If this is not right, please correct it.) |
The Legendre symbol is used by mathematicians in the theory of numbers, particularly in the fields of factorization? and [quadratic residues]?. |
Furthermore, if a is devisible by p we say (a/p) = 0. |
Furthermore, if a is divisible by p we say (a/p) = 0. |
