It is not only possible to animate a symbol from a point A to a point B but you can actually set as many intermediate points that you want.
Let's create a simple animation that demonstrates the above statement.
1. Create a new 400x400 Flash document with a frame rate of 24
2. Draw a basic circle and move it to the upper left corner of the scene (fig1)
fig1
3. create a motion tween on the first frame. (fig2)

4. Now you are going to create 4 more keyframes and each time we are going to move the circle to a corner of our stage. Have a look at the pictures below.
You will notice that we don't place the last keyframe on frame 50 but on frame 49, we do that to avoid a 1 frame delay in the animation since frame 1 and frame 50 would display the circle at the same position for 2 frames.
