Newton's force-acceleration equation

From The Portal Wiki
$$\mathbf{F} = m\mathbf{a}$$

The second law states that the rate of change of momentum of a body is directly proportional to the force applied, and this change in momentum takes place in the direction of the applied force.

F=ma is confusingly written and should be written better as a = F/m if you actually want to understand what it means.
