Ang Patakarang adisyon at subtraksiyon(Addition and Subtraction Rules) ay isang paraan upang mahanap ang deribatibo ng isang punsiyon.
![{\displaystyle {\frac {d}{dx}}\left[f(x)\pm g(x)\right]={\frac {d}{dx}}\left[f(x)\right]\pm {\frac {d}{dx}}\left[g(x)\right]}](https://wikimedia.org/api/rest_v1/media/math/render/svg/890764789354e817b69850d04926e1a6773313e1)
Mula sa depinisyon ng deribatibo:
![{\displaystyle \lim _{\Delta x\to 0}\left[{\frac {[f(x+\Delta x)\pm g(x+\Delta x)]-[f(x)\pm g(x)]}{\Delta x}}\right]}](https://wikimedia.org/api/rest_v1/media/math/render/svg/8abbd64362c04e963faff33257cd486b5ecc577b)

Sa pamamagitan ng kahulugan, ang huling termino ay ![{\displaystyle {\frac {d}{dx}}\left[f(x)\right]\pm {\frac {d}{dx}}\left[g(x)\right]}](https://wikimedia.org/api/rest_v1/media/math/render/svg/ef506c07a97f260c7649fd622782c878eaaff692)
