Proportional reasoning involves identifying how variables are changing with respect to each other. This is like asking, "If I turn this knob (change this variable), how will the machine (output of equation) respond? or how can I turn the rest of the knobs to compensate and retain the same answer?" This skill is useful for identifying causality in everyday life.
