Other programming areas that require math: Pattern recognition, control systems, encryption, image and video compression (discrete cosine transforms in JPEG, discrete wavelet transforms in JPEG2000) any type of simulation (e.g. SPICE for electronic component simulation, RF simulation for electromagnetism, finite element models for mechanical systems) ... Any type of planning system requires math (e.g. convex optimisation, network routing, etc...) - these types of things have huge applications in areas such as industrial engineering and network routing. Basically all the interesting parts of programming require math.
