A plus or minus symbol in a measurement indicates the uncertainty or variability associated with that measurement. For example, if a length is reported as 10 cm ± 0.5 cm, it means the actual length could be anywhere between 9.5 cm and 10.5 cm. This notation provides a range that reflects potential errors or variations in the measurement process.
