You'd probably use existing libraries for that sort of thing.

So you have "studied it many times" but have never understood anything about it? There are many numerical algorithms for approximate integration. Neither integration nor differentiation are "arithmetic" methods, they require the "limit" process (which you should have learned in the first semester of Calculus if not in a "preCalculus" course). Limits cannot be done numerically so the best a digital computer can do is an approximation.
