This math topic focuses on calculating the mean of a set of numbers after removing one value to achieve a specific target mean. Through multiple problems, students are challenged to identify which number should be removed from a list so that the resulting set of numbers averages to a given mean. This exercise helps enhance understanding of how the mean is affected by changes in data sets and sharpens problem-solving skills related to statistics.
