You can put this solution on YOUR website! If you're talking about a free-body diagram, it helps to be able to identify all forces acting on an object. This could include weight, friction, air resistance, the force of pushing or pulling, the normal force, etc. They add just like vectors do, since forces are vectors. To add vectors numerically, you have to split the forces into x and y components, and it is often best to choose a coordinate system such that accomplishing this will be easier.
