The document discusses using Hadoop MapReduce for large scale mathematical computations. It introduces integer multiplication algorithms like FFT, MapReduce-FFT, MapReduce-Sum and MapReduce-SSA. These algorithms can be used to solve computationally intensive problems like integer factoring, PDE solving, computing the Riemann zeta function, and calculating pi to high precision. The document focuses
