This math topic focuses on advanced exercises in understanding and calculating the mean (average) in statistics. Specifically, the problems require identifying what single value needs to be added to a given set of numbers to achieve a specified mean. Each question presents a different set of numbers and target means, challenging students to apply their knowledge of the mean formula dynamically across varying scenarios. This practice enhances students' abilities in statistical reasoning and manipulation of the mean.
