Examiners follow a detailed marking scheme for numericals. Even with a wrong final answer, you get method marks for correct steps, formula application, and unit handling. Forgetting to write the unit like m/s² typically costs just half a mark, but consistent carelessness adds up. Teaching my niece math, I see how those small marks saved by showing clear steps are like saving pennies for my mic—each one counts.
