It is the inverse of addition. A force may be resolved into several parts, such that addition of these forces provide the same force.
The most common two dimensional resolution of a force vector is into rectangular components. Let i and j be the unit vectors in the direction of x and y,
F = Fxi+Fyj
It can be easily shown that sum of the resolved components of several forces is equal to the resolved component of the forces.
