FMA (fused multiply-add) is a basic computing operation that is a basic building block in tasks such as evaluating polynomials, vector-vector and matrix-vector multiplication, convolutions, and also algorithms to solve nonlinear equations. You'd be hard pressed to find any computing application that doesn't take advantage of FMA instructions.
