Algorithms:

Simple Quadratic Form. Solve for x,y such that bxy+dx+ey=f where b,d,e,f,x,y in Z.

Euclidean Algorithm. Compute the Greatest Common Divisor (GCD) of two numbers a and b.

Extended Euclidean Algorithm. Solve for x, y such that ax + by = gcd(a, b).

Linear Diophantine Equation In Two Variables. Solve for x,y such that ax+by=c.

Linear Congruence In One Variable. Solve for x a congruence of the form ax ≡ b (mod m).

Linear Congruence In Two Variables. Solve for x,y, a congruence of the form ax+by ≡ c (mod m).

Tonelli-Shanks Algorithm. Calculate the Quadratic Residue Modulo. Solve for x, a congruence of the form x² ≡ a (mod p) where p is prime.

Mod Factors. Calculate modular possible factors for a given number and a modulus. Find n ≡ bc (mod a) where (ax + c)(ay + b) = a(axy + bx + cy) + bc = n.

Primes List. List of primes ordered in columns.

Note: Performance is based on the device.
