Example of calculations

The Legendre symbol (a / p) is only defined for odd primes p. It obeys the same rules as the Jacobi symbol (i.e., reciprocity and the supplementary formulas for (−1 / p) and (2 / p) and multiplicativity of the "numerator".)

Problem: Given that 9907 is prime, calculate (1001 / 9907).
