Class 6 Mathematics Chapter 10 The Other Side of Zero question answer
Other grids that allow multiple ways of filling can include those with several missing values along the outer edges. The reason for multiple solutions is the flexibility in combining positive and negative numbers to reach the same total. For example, placing different combinations of positive or negative integers can result in the same sum for the border. This flexibility in placement reflects the nature of integers and the various ways they interact mathematically to form consistent outcomes.
