If the number lines represent the number of [[Newton]]s [[force]] then the [[Resultant Force]] is the two values added together.
F<sub>ResultantR</sub> = (+2N) + (-4N)
F<sub>ResultantR</sub> = -2N upwards

If the number lines represent the number of [[Newton]]s [[force]] then the [[Resultant Force]] is the two values added together.
F<sub>ResultantR</sub> = (+3N) + (-2N)
F<sub>ResultantR</sub> = 1N to the right
