Neither statement is fully correct.

Correct explanation: parallel forces are forces whose lines of action are parallel (they may point in the same or opposite directions). They are added vectorially (or algebraically if you choose a sign convention). That means you assign a positive sign to one direction, negative to the opposite, then add magnitudes. The resultant can be positive or negative (indicating direction).

Examples:
- 5 N to the right and 3 N to the right → resultant = 8 N to the right.
- 5 N to the right and 8 N to the left → resultant = 3 N to the left (or −3 N if right is taken positive).
