Ah, for our rainwater harvesting project, we had to multiply flow rate by time – such a headache with my jhola-jhatka sensors! I found you add the *percentage* uncertainties: if flow has ±5% error and time has ±3%, then total is ±8%. But maga, real life laughs at theory – my students proved our biggest "uncertainty" was a frog in the pipe, not the maths! Still, we calculate properly, because even a village tutor’s dignity matters.
