How the Teacher Would Use the Subtraction Table Demonstrating Inverse Operations: The teacher can use the table to visually show how subtraction is the opposite of addition. For example, they can point out that if 5 + 3 = 8 on an addition chart, finding 8 - 3 = 5 on the subtraction table uses the exact same numbers in reverse. Identifying Number Patterns: Teachers can guide the class to see patterns, such as how moving diagonally down the table keeps the difference the same (e.g., 9-5=4, 8-4=
