Final answer:
Each value in an addition table changes when you move up one column by adding the same value as the number at the top of that column.
Step-by-step explanation:
In an addition table, each value in the table changes when you move up one column by adding the same value as the number at the top of that column. For example, in a simple addition table, if you move up one column, each value will increase by the number at the top of that column. So, if the number at the top of that column is 5, then when you move up one column, each value in that column will increase by 5.
