The equation force = mass x acceleration can be rewritten in a few ways, depending on what you're trying to solve for:

1. Solving for mass:

* mass = force / acceleration

2. Solving for acceleration:

* acceleration = force / mass

3. Using Newton's Second Law of Motion notation:

* F = ma (where F is force, m is mass, and a is acceleration)

These are all equivalent ways to represent the fundamental relationship between force, mass, and acceleration as described by Newton's Second Law of Motion.
